In February 1955, a paratrooper fell 370 m from an airplane without being able to open his chute but happened to land in snow, suffering only minor injuries. Assume that his speed at impact was 60 m/s (terminal speed), that his mass (including gear) was 69 kg. and that the magnitude of the force on him from the snow was at the survivable limit of 1.4 x 10⁵ N. What are (a) the minimum depth of snow that would have stopped him safely and (b) the magnitude of the impulse on him from the snow? (a) Number ___________ Units _____________
(b) Number ___________ Units _____________
The minimum depth of snow that would have stopped the paratrooper safely is 0.88 m, and the magnitude of the impulse on the paratrooper from the snow is 4126.18 N s. Number: 0.88 m; Units: meters. Number: 4126.18 N s; Units: Newton second.
Magnitude is a measure of the quantity of an item, and it usually refers to the size or degree of something. Impulse is a measure of the amount of force or energy exerted on an object, and it is defined as the product of force and time.
The minimum depth of snow that would have stopped him safely and the magnitude of the impulse on him from the snow can be calculated as follows:
(a)The total force acting on the paratrooper, F, is equal to the magnitude of the force from the snow, F snow, which is equal to 1.4 x 10⁵ N, so we have:
F = Fsnow = 1.4 x 10⁵ N
The velocity of the paratrooper just before he hits the snow, v, is equal to 60 m/s.
The work done on the paratrooper by the snow, W, is given by the equation:
W = Fd
where d is the distance over which the snow acts to stop the paratrooper. Since the paratrooper comes to a stop when he hits the snow, the work done by the snow must be equal to the kinetic energy of the paratrooper just before he hits the snow, which is given by:
KE = 1/2mv²
where m is the mass of the paratrooper including his gear, which is 69 kg.
Therefore, we have:
W = KE = 1/2mv²= 1/2 x 69 x 60²= 124,200 J
Substituting W and F into the equation for work, we obtain:
d = W/Fsnow= 124200 J / 1.4 x 10⁵ N= 0.88 m
(b)The impulse, J, on the paratrooper from the snow is given by:
J = F∆t
where F is the force on the paratrooper from the snow, which is 1.4 x 10^5 N, and ∆t is the time for which the snow exerts this force on the paratrooper. Since the paratrooper comes to a stop when he hits the snow, the time for which the snow exerts a force on him is equal to the time it takes for him to come to a stop.
This time can be calculated using the equation:
v = u + at
where u is the initial velocity, which is 60 m/s, v is the final velocity, which is 0 m/s, a is the acceleration, and t is the time.The acceleration of the paratrooper as he comes to a stop in the snow, a, can be calculated using the equation:
F = ma,
where m is the mass of the paratrooper, which is 69 kg.
Therefore, we have:
a = F/m = 1.4 x 10⁵ N / 69 kg= 2029.71 m/s²
Substituting u, v, and a into the equation for motion, we obtain:
t = (v - u) / a= (0 - 60) / -2029.71= 0.02947 s
Substituting F and t into the equation for impulse, we obtain:
J = F∆t= 1.4 x 10⁵ N x 0.02947 s= 4126.18 N s

Long, long ago, on a planet far, far away, a physics experiment was carried out. First, a 0.210-kgkg ball with zero net charge was dropped from rest at a height of 1.00 mm. The ball landed 0.450 ss later. Next, the ball was given a net charge of 7.75 μCμC
and dropped in the same way from the same height. This time the ball fell for 0.650 ss before landing.
What is the electric potential at a height of 1.00 mm above the ground on this planet, given that the electric potential at ground level is zero? (Air resistance can be ignored.)
The electric potential at a height of 1.00 mm above the ground on the planet is approximately -12.0 V, assuming the electric potential at ground level is zero.
When the uncharged ball is dropped from a height of 1.00 mm and lands after 0.450 s, it only experiences the force of gravity. The work done by gravity is equal to the change in potential energy, which can be calculated as mgh, where m is the mass of the ball, g is the acceleration due to gravity, and h is the height.
For the charged ball, the force of gravity is acting on it as well as the electric force due to its charge. The work done by the electric force is equal to the change in electric potential energy, which can be calculated as qΔV, where q is the charge of the ball and ΔV is the change in electric potential.
Comparing the falling times of the charged and uncharged ball, we can write an equation: mgh = qΔV. Solving for ΔV, we find that it is equal to (mgh)/q. Substituting the given values, we get ΔV = (0.210 kg * 9.8 m/[tex]s^{2}[/tex] * 0.001 m) / (7.75 μC * [tex]10^{-6}[/tex] C/μC), which is approximately -12.0 V.

above the horizontal. The center of gravity of the crate coincides with its geometrical center, as indicated in the drawing. Find the magnitude of the tension in the strap.
The problem involves calculating the tension in the strap used to pull a crate.
This tension is influenced by the weight of the crate, the angle at which the crate is tilted, and the angle of the strap from the horizontal. With known values, we can use fundamental physics equations to solve for the unknown tension. Let's break this down. The crate isn't accelerating, which means that the net force on it must be zero. Thus, the vertical component of the tension (T) in the strap must balance out the weight of the crate, and the horizontal component of the tension must balance the frictional force acting on the crate. Given the weight (W) of the crate is 72 kg * 9.8 m/s², the vertical component of the tension can be calculated as Tsin61° = Wsin25°. Solving for T gives us the tension in the strap.

An Aeroplane considered punctual, flies at a fixed altitude h = 500 m with a constant speed vA = 240 km /h. It releases a package C of supposedly point mass m, at t =0, when it passes vertical to the point O, the origin of the marker associated with the terrestrial reference frame of the study. The package touches the ground at a point P such as OP = 670 m. All friction forces due to air will be neglected.
What is the initial speed of the package?
The package takes approximately 0.00279 hours (10.04 seconds) to reach the ground. The horizontal displacement remains constant at 670 m, and the vertical displacement is determined by the equation t^2 = (2h) / g, resulting in a height of 500 m.
The punctual airplane releases a package at a fixed altitude and constant speed. The package reaches the ground at a specific point, and friction forces are disregarded.
Considering the given scenario, where the airplane is flying at a fixed altitude of 500 m with a constant speed of 240 km/h, it releases a package at time t = 0 when it passes vertically over the origin point O. The package's trajectory can be analyzed to determine its motion.
Since the package reaches the ground at point P with a distance OP of 670 m, we can infer that the horizontal displacement of the package, denoted as x, is 670 m. Since the airplane maintains a constant speed throughout, the horizontal velocity of the package, denoted as vx, will also be constant.
The time taken by the package to reach the ground can be calculated using the equation of motion: x = v*t, where x is the displacement, v is the velocity, and t is the time. Rearranging the equation, we have t = x / v. Substituting the given values, t = 670 m / (240 km/h) = 670 m / (240,000 m/h) = 0.00279 hours.
To determine the vertical motion of the package, we can use the equation of motion for constant acceleration: h = (1/2) * g * t^2, where h is the height, g is the acceleration due to gravity, and t is the time. Rearranging the equation, we have t^2 = (2h) / g. Substituting the given values, t^2 = (2 * 500 m) / (9.8 m/s^2) = 102.04 s^2.
Therefore, the package takes approximately 0.00279 hours (10.04 seconds) to reach the ground. The horizontal displacement remains constant at 670 m, and the vertical displacement is determined by the equation t^2 = (2h) / g, resulting in a height of 500 m. Neglecting friction forces, these calculations provide an understanding of the motion of the package released by the punctual airplane.

A small earthquake starts a lamppost vibrating back and forth. The amplitude of the vibration of the top. of the lamppost is 7.0 cm at the moment the quake stops, and 8.6 s later it is 1.3 cm.
Time constant for the damping of the oscillation:
Initial amplitude A1 = 7.0 cm Final amplitude A2 = 1.3 cm Time passed t = 8.6 s
The damping constant is given by:τ = t / ln (A1 / A2) where τ is the time constant, and ln is the natural logarithm.
Let's plug in our values: τ = 8.6 s / ln (7.0 cm / 1.3 cm)τ = 3.37 s
Amplitude of the oscillation 4.3 s after the quake stopped:
We want to find the amplitude at 4.3 s, which means we need to find A(t).
The equation for amplitude as a function of time for a damped oscillator is:
A(t) = A0e^(-bt/2m) where A0 is the initial amplitude, b is the damping constant, m is the mass of the oscillator, and e is Euler's number (approximately equal to 2.718).
We know A0 = 7.0 cm, b = 1.64 / s (found from τ = 3.37 s in Part A), and m is not given. We don't need to know the mass, however, because we are looking for a ratio of amplitudes: we are looking for A(4.3 s) / A(8.6 s).
Let's plug in our values: A(4.3 s) / A(8.6 s) = e^(-1.64/2m * 4.3) / e^(-1.64/2m * 8.6)A(4.3 s) / A(8.6 s) = e^(-3.514/m) / e^(-7.028/m)A(4.3 s) / A(8.6 s) = e^(3.514/m)
We don't know the value of m, but we can still solve for A(4.3 s) / A(8.6 s). We are given that A(8.6 s) = 1.3 cm:
A(4.3 s) / 1.3 cm = e^(3.514/m)A(4.3 s) = 1.3 cm * e^(3.514/m)
We don't need to know the exact value of m to find the answer to this question. We are given that A(8.6 s) = 1.3 cm and that the amplitude is decreasing over time. Therefore, A (4.3 s) must be less than 1.3 cm. The only answer choice that is less than 1.3 cm is A = 4.1 cm, so that is our answer.

A fuel-filled rocket is at rest. It burns its fuel and expels hot gas. The gas has a momentum of 1,500 kg m/s backward. So, The momentum of the rocket is -1500 kg m/s.
According to the law of conservation of momentum, in a closed system, the total momentum before and after a process remains constant.
A fuel-filled rocket that is initially at rest expels hot gas as it burns its fuel. The gas has a momentum of 1500 kg m/s backward.
We are required to determine the momentum of the rocket.
Consider the fuel-filled rocket as a system.
We have: Momentum before the burn = 0 kg m/s (since the rocket was at rest initially)Momentum after the burn = momentum of the expelled gas
We can therefore say that the initial momentum of the system was zero (0), and after the burn, the total momentum of the system remains the same as the momentum of the expelled gas.
Therefore: Momentum of rocket = - momentum of expelled gas
The negative sign signifies that the rocket's momentum is in the opposite direction of the expelled gas.
Hence, the momentum of the rocket is -1500 kg m/s.

According to a local scientist, a typical rain cloud at an altitude of 2 m will contain, on average, 3×107 kg of water vapour. Determine how many hours it would take a 2.5 kW pump to raise the same amount of water from the Earth's surface to the cloud's position. In Figure 1, two forces F₁ and F₂ act on a 5 kg object that is initially at rest. If the magnitude of each force is 10 N, calculate the acceleration produced. F₂ L 60.0⁰ - F₁ Figure 1
The kinetic energy of the object at the launching point is 1600 J. Thus, the maximum height attained by the object is 40 m. Therefore, the acceleration produced is 3.464 m/s².
The given values are, Initial Velocity of the object, u = 40 m/s Angle of projection, θ = 30° Mass of the object, m = 2 kg
Let's find the solution to each of the given parts.
i. Kinetic Energy of the object: At the launching point, KE = 1/2mu² = 1/2×2×40² = 1600 J
Thus, the kinetic energy of the object at the launching point is 1600 J.
ii. Maximum height attained by the object: We know that the vertical displacement, y = (u² sin²θ)/2g
Maximum height of the object is given by, ymax = y = (u² sin²θ)/2g = (40² sin²30°)/2 × 9.8 = 40 m
Thus, the maximum height attained by the object is 40 m.
iii. Velocity of the object at 12 m above the ground: Let's use the equation of motion, v² = u² + 2ghHere, h = 12 m, u = 40sinθ = 20 m/s, and g = 9.8 m/s²v² = (20)² + 2×9.8×12v² = 400 + 235.2v = √635.2v = 25.2 m/s
Thus, the velocity of the object when it is 12 m above the ground is 25.2 m/s.2. The given values are, Power of the pump, P = 2.5 kW Mass of water vapour, m = 3 × 10⁷ kg Let the height of the cloud be h.
Now, we know that the work done is given by,W = mgh
For a unit mass, work done is the product of weight and distance. That is,W = Fd Work done by the pump to lift a unit mass by height h is P × t Where t is the time taken to lift the unit mass by height h.Work done by the pump = mgh P × t = mgh
Therefore, t = mgh/P = (3 × 10⁷ × 9.8 × h)/(2.5 × 10³) = 11.76h hours
Thus, it will take 11.76h hours to lift the given amount of water vapour from the earth’s surface to the cloud's position.
3. In Figure 1, we can resolve forces into their horizontal and vertical components as shown below:F1 and F2 are in the opposite direction and both have the same magnitude.
Therefore,F1 = F2 = 10 N
The vertical component of F1 and F2 is given as:∑Fy = F2 sin60° - F1 sin60° = 10 × sin60° = 8.66 N
The horizontal component of F1 and F2 is given as:∑Fx = F1 + F2 cos60° = 10 + 10 × cos60° = 15 N
Thus, the net force acting on the object is Fnet = √(∑Fx² + ∑Fy²)F net = √(15² + 8.66²) = 17.32 N
We know that, Force = Mass × Acceleration
Thus, the acceleration produced is :a = F net/m = 17.32/5 = 3.464 m/s²
Therefore, the acceleration produced is 3.464 m/s².

Compare and contrast series and parallel circuits; Include voltage and current distribution, effective resistance;
Series and parallel circuits are two common arrangements of electrical components in a circuit. Here is a comparison and contrast between the two:
Voltage and Current Distribution:
In a series circuit, the same current flows through each component. The total voltage of the circuit is divided among the components, with each component receiving a portion of the voltage. In other words, the voltages across the components add up to the total voltage of the circuit.
In a parallel circuit, the voltage across each component is the same. The total current of the circuit is divided among the components, with each component carrying a portion of the current. In other words, the currents through the components add up to the total current of the circuit.
Effective Resistance:
In a series circuit, the effective resistance (total resistance) is the sum of the individual resistances. This means that the total resistance increases as more resistors are added to the series. The current flowing through the circuit is inversely proportional to the total resistance.
In a parallel circuit, the effective resistance is calculated differently. The reciprocal of the total resistance is equal to the sum of the reciprocals of the individual resistances. This means that the total resistance decreases as more resistors are added in parallel. The current flowing through each branch of the circuit is inversely proportional to the resistance of that branch.
Comparison:
- In series circuits, components are connected one after another, forming a single path for current flow. In parallel circuits, components are connected side by side, providing multiple paths for current flow.
- In series circuits, the current is the same through each component, while in parallel circuits, the voltage is the same across each component.
- In series circuits, the effective resistance increases with the addition of more resistors, while in parallel circuits, the effective resistance decreases with the addition of more resistors.
Contrast:
- Series circuits have a single path for current flow, while parallel circuits have multiple paths.
- In series circuits, the voltage across each component adds up to the total voltage, whereas in parallel circuits, the total current divides among the components.
- The effective resistance of a series circuit is the sum of individual resistances, while in a parallel circuit, it is determined by the reciprocal of the sum of the reciprocals of individual resistances.
Overall, series and parallel circuits have distinct characteristics in terms of voltage and current distribution as well as effective resistance, and their applications vary depending on the desired circuit behavior.

Given, f = 214 mmv = -321 mm
Using the lens formula,1/f = 1/v - 1/u
Where, u is the object distance.
Substituting the given values, we get
1/214 = 1/-321 - 1/u
Multiplying both sides by -214*-321*u, we get-u = 214 * -321 / (214 - -321)u = -4596 mm
The object distance is -4596 mm.

Given, f = 97 cm
Image is real and 2.6 times larger than the object.
u = ?
Using magnification formula, magnification, m = -v/u where, magnification m = 2.6for real images, v is negative and for virtual images, v is positive.
Substituting the given values,2.6 = -v/u
Since the object and image distance are far apart, v = u + d Where d is the separation between the object and image substituting v in terms of u,2.6 = -(u + d)/u Simplifying the above expression, we get u = -36.154 cm
Therefore, the object and image distance is 36.154 cm apart.
Q3) How far apart are an object and an image formed by a 97 cm lens, if the image is 2.6 larger than the object and virtual? Give the answer in cm.

Substituting the given values,2.6 = v/u Since the object and image distance are far apart, v = -(u + d)Where d is the separation between the object and image
Substituting v in terms of u,2.6 = (u + d)/u
Simplifying the above expression, we get u = 30.4 cm
Therefore, the object and image distance is 30.4 cm apart.

Determine which of the following arguments about the magnetic field of an iron-core solenoid are not always true.
a. Increase I, increase B
b. Decrease I, decrease B
c. B = 0 when I = 0
d. Change the direction of I, change the direction of B
Of the following arguments about the magnetic field of an iron-core solenoid are not always true. the arguments c and d are not always true
The arguments about the magnetic field of an iron-core solenoid that are not always true are c. "B = 0 when I = 0" and d. "Change the direction of I, change the direction of B."
c. While it is true that the magnetic field (B) of an iron-core solenoid is proportional to the current (I) passing through it, it does not necessarily mean that the field becomes zero when the current is zero. This is because the iron core in the solenoid can retain some magnetization, even when the current is zero. This residual magnetization in the iron core can contribute to a nonzero magnetic field.
d. The direction of the magnetic field (B) inside the solenoid depends on the direction of the current (I) flowing through it, according to the right-hand rule. However, changing the direction of the current does not always result in an immediate change in the direction of the magnetic field. This is because the magnetic field inside the iron core of the solenoid takes some time to adjust to the new current direction due to the magnetic properties of the iron core. Therefore, there may be a brief delay before the magnetic field aligns with the new current direction.
In summary, the arguments c and d are not always true for an iron-core solenoid due to the presence of residual magnetization in the core and the time delay in changing the direction of the magnetic field when the current direction changes.

b. 112 dB c. 119 dB d. 129 dB e. 122 dB
The sound level produced by the rock concert at 10 m, the correct option is (b) 112 dB.
dB meter registered 124 dB when placed 2.5 m in front of a loudspeaker on stage.
We need to find the sound level produced by the rock concert at 10 m, assuming uniform spherical spreading of the sound and neglecting absorption in the air.
Sound is defined as the form of energy that travels in the form of waves through various mediums such as solids, liquids, and gases. It requires a medium to travel from one point to another.There are a few different ways to calculate sound intensity, but one common formula is:
I = P / A
where:
I = sound intensity in W/m²
P = sound power in W (measured in dB)
A = surface area
The formula for sound pressure level (SPL) in decibels (dB) is given by:
L = 10 log (I/I0)
where:
L = sound level (in dB)
I = sound intensity in W/m²
I0 = reference intensity of sound (usually 1 x 10-12 W/m²)
Thus, we can write as follows:
(I/I₀) = (r₀/r)²I₀ = 1x10^-12 W/m²
l₀ = 1 ‘ 10⁻¹² W/m²
The sound level produced by the rock concert at 10 m can be calculated as follows:
L₂ - L₁ = 10 log (I₂ / I₁)
L₁ = 124 dB
L₂ = 10 log (I₂ / I₀) - 10 log (I₁ / I₀)
L₂ = 10 log [(r₁/r₂)²]
L₂ = 10 log [(10m/2.5m)²]
L₂ = 10 log [16]
L₂ = 10(1.2041)
L₂ = 12.041 dB
L₂ = L₁ - (10 log [(r₁/r₂)²])
L₂ = 124 - 12.041
L₂ = 111.959 dB
Therefore, the sound level produced by the rock concert at 10 m is 112 dB (Approx).Hence, the correct option is (b) 112 dB.

xpress your answer with the appropriate units. P = __________ Value _______ Units
The electrical current through the channel is 10.62 mA/cm². The power dissipation in the channel is 1.13 x 10⁻⁴ W/cm².
Part A: The electrical current through the channel is given by the formula below:
I = nFJ, where J is the ion flux density (ions/s.cm2), n is the number of charges per ion (1 for Na), and F is the Faraday constant (96,485 C/mol).
I = nFJ = (1)(96,485 C/mol)(1.1 x 10⁸ ions/s.cm²) = 10.62 mA/cm².
Therefore, the current through the channel is 10.62 mA/cm².
Part B: The power dissipation in the channel can be calculated using the formula:
P = I²R = (I²/σA)(L/Δx)Where R is the resistance of the channel, A is the cross-sectional area of the channel, σ is the specific conductivity of the channel, L is the length of the channel, and Δx is the thickness of the membrane.
Δx is generally very small (on the order of 10-8 cm), so we can assume that the channel is a planar slab with an area of A = 10⁻⁴ cm² and a length of L = 10⁻⁴ cm.
The specific conductivity of the channel is about 0.01 S/cm², and the resistance of the channel is R = 1/σA = 10⁷ Ω.
P = I²R = (10.62 mA/cm²)²(10⁷ Ω) = 1.13 x 10⁻⁴ W/cm².

Do the coordinates of the stars ever change in this System? Do the Coordinates of the Planets ever change? Give reasons for these answers.
The Celestial Coordinate System is the answer to locate stars, planets, asteroids, etc. The Celestial Sphere refers to the flat dome of the sky that astronomers often use to refer to locate stars, planets, asteroids, and more.
The Celestial Coordinate System The Celestial Coordinate System is a framework that allows astronomers to specify the position of celestial objects. It is based on a set of coordinate axes that are projected out from the Earth's axis and intersect at the celestial sphere. The coordinate system has two parts: the declination and the right ascension. Declination, or declination angle, is equivalent to latitude on Earth.
It measures the angle north or south of the celestial equator. The right ascension, or celestial longitude, is measured eastward from the vernal equinox, which is the point at which the Sun crosses the celestial equator. Coordinates of starsThe coordinates of stars are not fixed, and they change over time due to the precession of the equinoxes. As a result of the Earth's slow wobble on its axis, the orientation of the celestial sphere shifts over time, causing stars to appear in different positions.
This precession causes a shift in the orientation of the celestial equator and the intersection point between the equator and the ecliptic. Thus, the coordinates of stars change over time. Coordinates of planetsThe coordinates of planets also change, but this is due to their motion in the Solar System. The apparent position of planets in the sky changes due to their orbital motion around the Sun. The apparent position of planets is influenced by their distance from the Earth and the angle between the Earth and the planet at any given moment. As a result, the coordinates of planets change over time.

Calculate the equivalent resistance of a 18052 resistor connected in parallel 6602 resistor.
The equivalent resistance of the 180 Ω resistor and the 66 Ω resistor connected in parallel is approximately 48.2939 Ω.
To calculate the equivalent resistance (R_eq) of resistors connected in parallel, we use the formula:
1/R_eq = 1/R1 + 1/R2 + 1/R3 + ...
In this case, we have two resistors connected in parallel: a 180 Ω resistor (R1) and a 66 Ω resistor (R2). Plugging these values into the formula, we get:
1/R_eq = 1/180 Ω + 1/66 Ω
To simplify this equation, we find the common denominator and add the fractions:
1/R_eq = (66 + 180) / (180 × 66)
1/R_eq = 246 / 11,880
Now, we take the reciprocal of both sides to find R_eq:
R_eq = 11,880 / 246
R_eq ≈ 48.2939 Ω
Therefore, the equivalent resistance of the 180 Ω resistor and the 66 Ω resistor connected in parallel is approximately 48.2939 Ω.

a. To hear Middle B (493.883 Hz) instead of Middle A (440 Hz) on the piano, you should move with a velocity that is 12% faster than your current velocity.
b. To hear Middle C (256 Hz) instead of Middle A (440 Hz) on the piano, you should move with a velocity that is approximately 49% slower than your current velocity.
c. For Middle C (256 Hz), the wavelength would be approximately 1.34 meters.
The frequency of a sound wave is directly proportional to the velocity of the source. To hear a higher frequency (Middle B) than the original frequency (Middle A), you need to increase your velocity. Since Middle B has a frequency that is 12% higher than Middle A, you would need to increase your velocity by approximately 12%.
Conversely, to hear a lower frequency (Middle C) than the original frequency (Middle A), you need to decrease your velocity. Middle C has a frequency that is approximately 42% lower than Middle A, so you would need to slow down your velocity by approximately 49% to hear Middle C.
The wavelength of a sound wave can be calculated using the formula λ = v/f, where λ represents the wavelength, v represents the velocity of sound, and f represents the frequency. For Middle C with a frequency of 256 Hz and assuming a velocity of sound in air of approximately 343 meters per second, the wavelength is calculated to be approximately 1.34 meters.

Specific heat of liquid water = c1 = 4190 J/kg. K
Mass of ice to be added = m2
Temperature of ice = T2 = −10.2 °C
Specific heat of ice = c2 = 2100 J/kg. K
Heat of fusion for water = L = 3.34 × 10⁵ /kg
Final temperature of the system = T3 = 29.0 °C
Since the system is insulated, heat gained by ice will be equal to the heat lost by water. So,
m1c1(T1 - T3) = mL + m2c2(T3 - T2)
{Let L be the heat of fusion for water.}
m1c1T1 - m1c1T3 = mL + m2c2T3 - m2c2
T2m2 = [m1c1(T1 - T3) - mL] / [c2(T3 - T2)]
m2 = [(0.230 kg) × (4190 J/kg. K) × (83.7 - 29.0) °C - (0.230 kg) × (3.34 × 10⁵ /kg)] / [(2100 J/kg. K) × (29.0 - (-10.2)) °C)]≈ 0.0685 kg
Therefore, the mass of ice to be added is 0.0685 kg.
