To calculate the mean and mode of a set of numbers in C, you need to read the input size, followed by the numbers themselves. Then, you can calculate the mean by summing up the numbers and dividing by the count.
To find the mode, you can create a frequency table to count the occurrences of each number and determine the number(s) with the highest frequency. Finally, you can print the mean and mode with two decimal places.
In C, you can start by reading the input size, inputArr_size, using scanf(). Then, you can declare an array inputArr of size inputArr_size to store the numbers. Use a loop to read the numbers into the array.
To calculate the mean, initialize a variable sum to 0 and use another loop to iterate through the array, adding each number to sum. After the loop, divide sum by inputArr_size to obtain the mean.
To calculate the mode, you can create a frequency table using an array or a hash map. Initialize an array frequency of size inputArr_size to store the frequency of each number. Iterate through inputArr and increment the corresponding frequency in frequency for each number.
Next, find the maximum frequency in frequency. Iterate through frequency and keep track of the maximum frequency value and its corresponding index. If there are multiple numbers with the same maximum frequency, store them in a separate array modeNumbers.
Finally, print the mean and mode. Use printf() to display the mean with two decimal places (%.2f). For the mode, iterate through modeNumbers and print each number with two decimal places as well.

This signal is received by an FM receiver with an ideal frequency discriminator. The receiver equivalent noise bandwidth is equal to the signal bandwidth as given by Carson's rule and the output LPF bandwidth is just sufficient to pass all frequencies of the messages. If the receiver input SNR, i.e. (CNR) F, is 10 dB, find S the output SNR, .(10 points) N
The output SNR of the FM receiver is approximately 3.01.
To find the output SNR of the FM receiver, we need to consider the input SNR and the properties of the receiver.
The input SNR, or Carrier-to-Noise Ratio (CNR), is given as 10 dB. We can convert this to a linear scale:
CNR_linear = 10^(CNR/10) = 10^(10/10) = 10
Next, we need to calculate the noise power at the output of the receiver. Since the receiver's equivalent noise bandwidth is equal to the signal bandwidth (as given by Carson's rule), the noise power can be determined as:
N = CNR_linear / 2
Now, we need to calculate the signal power at the output of the receiver. For this, we need to consider the message signal and its properties.
The message signal is a band-limited Gaussian message with a spectral power density of If1/2. The maximum frequency deviation is given as 3 kHz, and the RMS voltage Vrms can be obtained from the signal power under a resistance of 112.
Since the message signal is Gaussian, its power is given by the formula:
S = 2 * pi * If1^2 * Vrms^2
Substituting the given values, we have:
S = 2 * pi * (2 * 10^10 Hz)^2 * (3 * 112^2 V)^2
Now, we can calculate the output SNR:
output SNR = S / N
Substituting the calculated values, we find:
output SNR ≈ 3.01
The output SNR of the FM receiver, given the input SNR of 10 dB and the properties of the receiver and message signal, is approximately 3.01.

1) How does IR radiation affect absorbing molecules? Name an example molecule that does not absorb IR and briefly explain why. 2) Suppose you are able to figure out, correctly, all of the functional groups for an unknown organic molecule using FTIR. Explain why this might not be sufficient to pin down the exact structure of the molecule. What additional information could be useful?
1. IR radiation affects absorbing molecules by causing them to vibrate, and this vibration results in an increase in the molecule's internal energy.
This increase in internal energy can cause various effects on the absorbing molecule, such as breaking or forming bonds. An example molecule that does not absorb IR is a molecule consisting only of two atoms of the same element (such as O2 or N2), which does not absorb IR radiation because it does not have a dipole moment.
2. Knowing all of the functional groups of an unknown organic molecule using FTIR might not be enough to determine its structure because many different molecules can have the same functional groups. For instance, both ethanol and dimethyl ether have the same functional group (i.e., the -O-H group). However, ethanol has a different structure from dimethyl ether, and these molecules have different physical and chemical properties.
Therefore, additional information might be required to determine the structure of an unknown organic molecule accurately. Such additional information could include the following:

A 13 m tank contains nitrogen at temperature 17°C and pressure 600 kPa. Some nitrogen is allowed to escape from the tank until the pressure in the tank drops to 400 kPa. If the temperature at this point is 15 °C and nitrogen gas behave in ideal gas condition, determine the mass of nitrogen that has escaped in kg unit.
The mass of nitrogen that has escaped from the tank is approximately 33.33 kg.
To determine the mass of nitrogen that has escaped, we can use the ideal gas law equation: PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.
First, we need to calculate the initial number of moles of nitrogen in the tank. We can use the equation [tex]n =[/tex] [tex]\frac{PV}{RT}[/tex], where P is the initial pressure, V is the volume, R is the ideal gas constant, and T is the initial temperature. Plugging in the values, we have n = (600 kPa * 13 m³) / (8.314 Jmol⁻¹K⁻¹) * 290 K), which gives us approximately 28.97 moles.
Next, we can use the same equation to calculate the final number of moles of nitrogen when the pressure drops to 400 kPa at a temperature of 15 °C. Using the new pressure and temperature values, we have n' = (400 kPa * 13 m³) / (8.314 Jmol⁻¹K⁻¹ * 288 K), which gives us approximately 19.31 moles.
The mass of nitrogen that has escaped can be calculated by finding the difference between the initial and final number of moles and multiplying it by the molar mass of nitrogen (28.0134 g/mol). Thus, the mass of nitrogen that has escaped is approximately (28.97 - 19.31) mol * 28.0134 g/mol = 33.33 kg.

Given Vo=3.5 angle122, V1=5.0 angle -10 , V2=1.9 angle92, find the phase sequence components Va, Vb and Vc.
The phase sequence components Va, Vb, and Vc are:
Va = 4.535 angle 27.5°
Vb = 1.358 angle -92.5°
Vc = -0.719 angle -152.5°
To find the phase sequence components Va, Vb, and Vc, we need to convert the given voltages Vo, V1, and V2 into their rectangular form and then perform the necessary calculations.
Vo = 3.5 angle 122°
V1 = 5.0 angle -10°
V2 = 1.9 angle 92°
Converting to Rectangular Form:
To convert the polar form to rectangular form, we use the following formulas:
For a voltage V with magnitude |V| and phase angle θ:
Real part (Vr) = |V| * cos(θ)
Imaginary part (Vi) = |V| * sin(θ)
Using these formulas, we can calculate the rectangular form for each voltage:
Vo = 3.5 * cos(122°) + j * 3.5 * sin(122°)
= -1.9125 + j * 3.0654
V1 = 5.0 * cos(-10°) + j * 5.0 * sin(-10°)
= 4.8971 - j * 0.8620
V2 = 1.9 * cos(92°) + j * 1.9 * sin(92°)
= -0.5608 + j * 1.8784
Phase Sequence Components Calculation:
The phase sequence components are obtained by applying the Park's transformation or Clarke's transformation to the given voltages.
Using Park's transformation, we have:
Va = 2/3 * (V0 - 0.5 * V1 - 0.5 * V2)
Vb = 2/3 * ((√3/2) * V1 - (√3/2) * V2)
Vc = 2/3 * (0.5 * V1 + 0.5 * V2)
Substituting the rectangular forms of the voltages, we get:
Va = 2/3 * (-1.9125 + j * 3.0654 - 0.5 * (4.8971 - j * 0.8620) - 0.5 * (-0.5608 + j * 1.8784))
= 4.535 angle 27.5°
Vb = 2/3 * ((√3/2) * (4.8971 - j * 0.8620) - (√3/2) * (-0.5608 + j * 1.8784))
= 1.358 angle -92.5°
Vc = 2/3 * (0.5 * (4.8971 - j * 0.8620) + 0.5 * (-0.5608 + j * 1.8784))
= -0.719 angle -152.5°
The phase sequence components Va, Vb, and Vc are calculated as follows:
Va = 4.535 angle 27.5°
Vb = 1.358 angle -92.5°

When the voltage drop of a system is too great, a system designer can typically do to fix this problem by increasing the size of the wires used. Increasing the size of wires is a way to minimize the voltage drop across a circuit. When current flows through a wire, it will experience resistance, and this resistance causes a voltage drop along the wire. The resistance of a wire increases with its length, and decreases with its cross-sectional area (thickness).
Therefore, using larger wires with a smaller cross-sectional area will reduce resistance and hence minimize the voltage drop.The voltage drop across a circuit is calculated by using Ohm's law: V = I x R, where V is the voltage drop across the wire, I is the current flowing through the wire, and R is the resistance of the wire.

Which of these molecules is linear? o BeF2 O OCl2 O NO2 O SO
Among the given molecules, BeF2 and OCl2 are linear.
A linear molecule is one in which all the atoms are arranged in a straight line. In order to determine whether a molecule is linear, we need to examine its molecular geometry and bonding.
Starting with BeF2 (beryllium fluoride), it consists of two fluorine atoms bonded to a central beryllium atom. The beryllium atom has only two valence electrons and forms two sigma bonds with the fluorine atoms. Since there are no lone pairs of electrons on the central atom, the molecule has a linear geometry.
Moving on to OCl2 (oxygen dichloride), it contains one oxygen atom and two chlorine atoms. The oxygen atom forms two sigma bonds with the chlorine atoms, and there are two lone pairs of electrons on the oxygen atom. Despite the presence of lone pairs, the molecule adopts a linear shape due to the repulsion between the electron pairs.
On the other hand, NO2 (nitrogen dioxide) and SO2 (sulfur dioxide) do not have linear geometries. NO2 consists of a nitrogen atom bonded to two oxygen atoms with a lone pair of electrons on the nitrogen atom, resulting in a bent shape. Similarly, SO2 has a bent shape due to the presence of a lone pair on the sulfur atom and two oxygen atoms.

Sketch the corresponding phasor diagram (Assume IF is still unchanged).
The magnitude of EA is 16431.626 volts and the torque angle of the generator at rated conditions is 109.4357°. If the field current is constant, the maximum power possible out of this generator is 28.8 watts.
The given data is:
A 13.8-kV 10-MVA 0.8-PF-lagging 60-Hz,
two-pole Y-connected steam turbine generator has a synchronous reactance of 12 2 per phase and an armature resistance of 1.5 per phase. The friction and windage losses are 40 KW and core losses are 30 KW.
A) To calculate the magnitude of EA, we need to use the following formula: EA = Vt + Ia * (Ra cos Φ + Xs sin Φ)
The given generator is two poles, so it rotates at 3600 rpm;
hence, frequency f = 60 Hz.
So, the synchronous reactance per phase Xs = 12.2 ohms.
The armature resistance per phase Ra = 1.5 ohms.
The power factor is lagging, so Φ = cos⁻¹(0.8) = 36.8699°.
Core losses are 30 KW, so the stator input power is P = 10 MVA + 30 KW = 10030 KW.
And, the active power P = 10 MW * 0.8 = 8 MW.
So, the stator current is Ia = P / (3 * Vt * PF) = 8 * 10⁶ / (3 * 13.8 * 10³ * 0.8) = 304.94 A.
Substituting the given values in the above equation,
we get:
EA = 13800 + 304.94 * (1.5 cos 36.8699° + 12.2 sin 36.8699°)= 13800 + 304.94 * (0.928 + 7.713)= 13800 + 304.94 * 8.641= 13800 + 2631.626= 16431.626 volts
Torque angle δ is given by the formula: cos δ = (Vt cos Φ - EA) / (Ia Xs)
Substituting the given values, we get
cos δ = (13800 cos 36.8699° - 16431.626) / (304.94 * 12.2)cos δ
= (-1119.1768) / 3721.388cos
δ = -0.3006169So,
δ = 109.4357°
Hence, the magnitude of EA is 16431.626 volts and the torque angle of the generator at rated conditions is 109.4357°.
B) For the maximum power developed by the generator, the torque produced must be maximum. Hence, we know that the power developed by the generator is given by,
Power = PΦNZ/60A= E × I= I²R
The armature resistance is neglected so the power developed is directly proportional to the square of the current. Therefore, the maximum power is developed when the armature current is maximum. The current through the armature winding depends on the load resistance. If the load resistance is very small, the armature current will be very high. Hence, for maximum power, the load resistance must be very small. If the load resistance is very small, then the output power will be equal to the generated power.
So, Maximum power
Pmax = E² / RHere, E = 4.8 V, R = 0.8 ohm
Pmax = 4.8² / 0.8 = 28.8 watt
Reserve power or torque at full load:
The output power at full load is given by,
Poutput = Voutput
IaHere, Voutput = 240 V (Given),
Poutput = 3 kW (Given)
Therefore,
Ia = 3 kW / 240 V = 12.5 Amps
Also, E = V + IaRa= 240 + (12.5 × 0.8) = 250 volts
D) The maximum power that can be developed is 28.8 watts. Hence, the reserve power at full load is given by,
Preserve = Pmax – Poutput= 28.8 - 3,000= -2,971.2 W
The generator is working on the inductive load, hence the reactive power supplied by the generator is lagging.
The reactive power is given by,Q = √(S² - P²)Q = √[(3 kVA)² - (2.88 kVA)²]= 1.62 kVAR. (Reactive Power supplied by the generator).
Phasor diagram: The phasor diagram is given below: The angle between the voltage and current is the power factor angle. As the generator is working on an inductive load, the power factor angle is positive. The reactive power is lagging.

The pressure just upstream and downstream of a hydraulic turbine are measured to be 1325 and 100 kPa, respectively. What is the maximum work, in kJ/kg, that can be produced by this turbine? If this turbine is to generate a maximum power of 100 kW, what should be the flow rate of water through the turbine, in L/min? (p = 1000 kg/m³ = 1 kg/L).
The maximum work that can be produced by the turbine is 1225 kJ/kg, and the flow rate of water through the hydraulic turbines should be approximately 4897.8 L/min to generate a maximum power of 100 kW.
Given:
Upstream pressure (P1) = 1325 kPa
Downstream pressure (P2) = 100 kPa
To determine the maximum work that can be produced by the hydraulic turbine, we can use the Bernoulli's equation, which relates the pressure difference across the turbine to the maximum work output.
The maximum work (W) can be calculated using the formula:
W = (P1 - P2) / ρ
where ρ is the density of the fluid.
Given:
Fluid density (ρ) = 1000 kg/m³ = 1 kg/L
Substituting the given values:
W = (1325 kPa - 100 kPa) / 1 kg/L
W = 1225 kPa / 1 kg/L
W = 1225 kJ/kg
Therefore, the maximum work that can be produced by the turbine is 1225 kJ/kg.
To determine the flow rate of water through the turbine, we can use the formula:
Power (P) = Flow rate (Q) * Work (W)
Given:
Maximum power (P) = 100 kW
We need to convert the power to kJ/s:
1 kW = 1000 J/s
100 kW = 100,000 J/s = 100,000 kJ/s
Substituting the given values:
100,000 kJ/s = Q * 1225 kJ/kg
Solving for Q:
Q = (100,000 kJ/s) / (1225 kJ/kg)
Q ≈ 81.63 kg/s
To convert the flow rate to L/min:
1 kg/s = 60 L/min
81.63 kg/s = 81.63 * 60 L/min
Q ≈ 4897.8 L/min
Therefore, the flow rate of water through the turbine should be approximately 4897.8 L/min to generate a maximum power of 100 kW.
Hence, the maximum work that can be produced by the turbine is 1225 kJ/kg, and the flow rate of water through the hydraulic turbines should be approximately 4897.8 L/min to generate a maximum power of 100 kW.

The water utility requested a supply from the electric utility to one of their newly built pump houses. The pumps require a 400V three phase and 230V single phase supply. The load detail submitted indicates a total load demand of 180 kVA. As a distribution engineer employed with the electric utility, you are asked to consult with the customer before the supply is connected and energized. i) With the aid of a suitable, labelled circuit diagram, explain how the different voltage levels are obtained from the 12kV distribution lines. (7 marks) ii) State the typical current limit for this application, calculate the corresponding kVA limit for the utility supply mentioned in part i) and inform the customer of the repercussions if this limit is exceeded. (7 marks) iii) What option would the utility provide the customer for metering based on the demand given in the load detail? (3 marks) iv) What metering considerations must be made if this load demand increases by 100% in the future? (2 marks) (b) You built an electric device for a design project that works on the 115V supply from a general-purpose domestic outlet. To be safe, you opt to use a fuse to protect the electrical components of the device from overvoltage in the supply or accidental faults in the circuitry. With the aid of a suitable diagram, show how the fuse would be connected to the terminals of your device and describe its construction and operation.
i) Different voltage levels obtained from 12kV distribution linesA 12kV transmission line is a high voltage power line that carries electrical power over long distances.
This high voltage is reduced to a safer level before distribution to the consumer. At the substation, the high voltage is stepped down to 415V or 240V for consumer use. The diagram below illustrates how this is accomplished.
ii) Typical current limit, the corresponding kVA limit, and repercussions if this limit is exceededThe typical current limit for this application is 400A.180 kVA = 1.732 * 400V * I1, where I1 is the three-phase current, hence I1 = 310.3A.180 kVA = 230V * I2, where I2 is the single-phase current, hence I2 = 782.6A.The total current demand is given by I = I1 + I2 = 1092.9A.Since the maximum current limit is 400A, the current demand for the customer would be three times higher than the maximum limit.
The system would trip in case of such an overload.iii) The option provided for metering based on the demand given in the load detailTo meter based on the given demand, the customer will be provided with a split-meter, which will measure the load separately for single-phase and three-phase supplies.
iv) Metering considerations to make if this load demand increases by 100% in the futureIf the load demand increases by 100%, additional meters will be installed to keep track of the increased demand. These meters will be installed on a separate branch to prevent overloading of the main metering system.
(b) Connection of fuse to the electric deviceThe fuse protects electrical components of the device from overvoltage in the supply or accidental faults in the circuitry. It is connected in series with the device and will blow out when a fault occurs, thus protecting the device from damages.

Here, in order to determine the values of labeled voltages and currents assuming the constant voltage drop model (Vp-0.7V), we use the Kirchhoff's laws.
Therefore,Applying Kirchhoff’s Current Law (KCL) to Node 1: `10 = (I1 + I2)`.........(1)
where, `I1` and `I2` are the currents flowing through 10Ω and 180Ω resistors respectively.
Applying Kirchhoff’s Voltage Law (KVL) to Mesh 1:`0 = 10I1 + Vp - 0.7 + 180I2`...........(2)
where, `Vp` is the voltage of the voltage source.
In addition, Applying KVL to Mesh 2: `-16 = -10 + 310I2 + 180I2`............(3)
From equation (3),`-16 + 10 = 490I2` ⇒ `I2 = -6 / 49`
From equation (1),`I1 = 10 - I2 = 490 / 49`
Putting value of `I2` in equation (2),`0 = 10(490 / 49) + Vp - 0.7 + 180(-6 / 49)
`On solving above equation, we get,`Vp = -5.69V`
Therefore, the voltage of the voltage source is `-5.69V`. And, `I1 = 10 - I2 = 490 / 49` and `I2 = -6 / 49` which are the currents flowing through 10Ω and 180Ω resistors respectively.
In the given problem, Kirchhoff's laws were used to find the values of labeled voltages and currents assuming the constant voltage drop model (Vp-0.7V). The current flowing through 10Ω and 180Ω resistors are `I1` and `I2` respectively. The voltage of the voltage source is `Vp`. On applying Kirchhoff’s Current Law (KCL) to Node 1, we get the equation (1) as 10 = (I1 + I2). By applying Kirchhoff’s Voltage Law (KVL) to Mesh 1, we obtain equation (2) as 0 = 10I1 + Vp - 0.7 + 180I2. Applying KVL to Mesh 2, we get the equation (3) as -16 = -10 + 310I2 + 180I2.

The required ratio of the motor starting torque T, to the maximum torque Tmax, is Ts 2 Tmax 1 sm ܪ Sm 1, given that the stator resistance of a three-phase induction motor is negligible.
Given data:
The three-phase induction motor's stator resistance is negligible. The ratio of motor starting torque T to the maximum torque Tmax can be expressed as Ts 2 Tmax 1 sm ܪ Sm 1
The formula for the torque of a three-phase induction motor is given by: T = (3V^2/Z2) * (R2 / (R1^2 + X1 X2)) * sin(δ)N1 s(1 - s)
where R1 is the resistance of the stator winding, X1 is the reactance of the stator winding, R2 is the rotor winding resistance, X2 is the reactance of the rotor winding, N1 is the supply frequency,s is the slip, and V is the voltage applied to the stator winding.
Now, since stator resistance is negligible, R1 is close to zero.
Therefore, we can assume the following formula:
Ts / Tmax = 2 / [s_rated * (1-s_max)]
Putting the value of Tmax, we get:
Ts / Tmax = 2 / [s_rated * (1-s_max)] = 2 / (s_max)
Using sm as the per-unit slip at which the maximum torque occurs, we get:s_max = sm, which means:
Ts / Tmax = 2 / (sm)
Therefore, the required ratio of the motor starting torque T, to the maximum torque Tmax, is Ts 2 Tmax 1 sm ܪ Sm 1, given that the stator resistance of a three-phase induction motor is negligible.

A power system is operating on economic load dispatch. If raising the output of Plant 2 by 100 kw, keeping all other outputs constant, results in a system real I'R power loss of 15kw, determine the Plant 2 penalty factor.
The penalty factor for Plant 2 in the economic load dispatch system can be determined by analyzing the change in system real power loss when the output of Plant 2 is increased by 100 kW, while keeping all other outputs constant.
In economic load dispatch, the goal is to minimize the overall cost of power generation while meeting the demand. The penalty factor is a measure of the sensitivity of the system's real power loss to changes in the output of a particular plant.
To determine the penalty factor for Plant 2, we analyze the change in system real power loss when the output of Plant 2 is increased by 100 kW, while keeping the outputs of all other plants constant. We observe that the system real power loss increases by 15 kW as a result of this change.
The penalty factor for Plant 2 can be calculated using the formula:
Penalty Factor = (Change in System Real Power Loss) / (Change in Plant 2 Output)
In this case, the change in system real power loss is 15 kW, and the change in Plant 2 output is 100 kW. Therefore, the penalty factor for Plant 2 can be calculated as:
Penalty Factor = 15 kW / 100 kW = 0.15
Hence, the penalty factor for Plant 2 is 0.15. This indicates that for every 1 kW increase in Plant 2's output, the system real power loss will increase by 0.15 kW.

The calculation of change in electric potential energy involves the use of the formula given below:ΔU = Uf - Ui. ΔU represents the change in potential energy, Uf is the final potential energy, and Ui is the initial potential energy.
Initially, when particles A and B are brought from infinity to a distance of 10 cm apart, the initial potential energy (Ui) will be zero since the distance between them is considered to be infinite, therefore there is no electric potential energy between them.
However, when two charged particles are brought together, the electric potential energy (Uf) of the system changes. The formula to calculate electric potential energy is given by: U = kQ1Q2/r. Here, U represents the electric potential energy, Q1 and Q2 are the charge of the respective particles, r is the separation between the two charged particles, and k is Coulomb's constant, which is 9 × 10^9 Nm^2/C^2.
To calculate the electric potential energy of the system (Uf), where two isolated charged particles A and B, having charges of 1.0 uC and 4.0 µC respectively, are brought from infinity to within a separation of 10 cm, we can use the formula: Uf = k Q1 Q2/r = (9 × 10^9 Nm^2/C^2) × (1.0 × 10^-6 C) × (4.0 × 10^-6 C)/(0.1 m) = 3.6 × 10^-5 J.
Finally, the change in electric potential energy (ΔU) can be calculated by using the formula given below: ΔU = Uf - Ui = (3.6 × 10^-5 J) - 0 = 3.6 × 10^-5 J. The negative value (-1.44 x 10^-5 J) indicates that the potential energy of the system has decreased.

1. When an "add" operation is executed, the datapath elements accessed are the instruction memory, register file, and ALU (Arithmetic Logic Unit).
2. Single-cycle processors with a unified memory can exhibit both structural and data hazards. The execution of the "add" operation involves fetching the instruction from the instruction memory, reading the operands from the register file, and carrying out the addition operation in the ALU. The result is then written back into the register file. The data memory is not used in this operation, as it is typically involved when dealing with load and store instructions. In a single-cycle processor with one unified memory, hazards can occur. A structural hazard may arise when the processor attempts to perform a fetch and a memory operation simultaneously, as these both require access to the same memory unit. Data hazards occur when instructions that depend on each other are executed in succession. For example, if one instruction is writing a result to a register while the next instruction reads from the same register, it might read the old value before the new value has been written, leading to incorrect computations.

Have the output use the following format (the actual number of digits displayed for the exponent depends on the system): I Enter a floating-point value: 64.25. fixed-point notation: 64.250000 exponential notation: 6.425000e+011 p notation: 0x1.01p+6
In C programming language, to write a program that reads in a floating-point number and prints it in decimal-point notation, exponential notation, and, if your system supports it, p notation, you can use the following code:#include int main() { float num; printf("Enter a floating-point value: "); scanf("%f",&num); printf("fixed-point notation:
%.6f\n",num); printf("exponential notation: %e\n",num); printf("p notation: %a",num); return 0;}This program uses scanf() function to read the input float value and then uses printf() function to display the output in decimal-point notation, exponential notation, and p notation in the specified format.

ii) The basic principle of a transmission gate in CMOS design is to create a switch-like behavior that allows signals to pass through or be blocked based on the control input. It consists of a PMOS (P-type Metal-Oxide-Semiconductor) and an NMOS (N-type Metal-Oxide-Semiconductor) transistor connected in parallel. When the control input is high, the PMOS transistor conducts, allowing the signal to pass through. When the control input is low, the NMOS transistor conducts, blocking the signal. This allows for bidirectional signal flow and can be used for various purposes such as signal routing and level shifting.
