Answer:

To solve this problem, we need to use the conservation of energy principle. The potential energy of the block at the top of the incline is converted into kinetic energy as it slides down the incline. However, some of this energy is lost due to friction between the block and the incline. Let's start by calculating the potential energy of the block at the top of the incline:

where m is the mass of the block, g is the acceleration due to gravity, and h is the height of the incline.

Next, we can calculate the kinetic energy of the block at the bottom of the incline:

where m is the mass of the block and v is its velocity at the bottom of the incline.

The energy lost due to friction is simply the difference between the potential energy at the top and the kinetic energy at the bottom:

The focal length of the lens is 15 cm. The correct option is C).

Using the thin lens equation

1/f = 1/d_o + 1/d_i

where f is the focal length of the lens, d_o is the object distance, and d_i is the image distance.

We are given that the object height, h_o, is 1.15 cm, the image height, h_i, is 5.75 cm, and the object distance, d_o, is 12 cm. Since the image is upright, the magnification, M, is positive:

M = h_i / h_o = 5.75 / 1.15 = 5

We can use the magnification equation to find the image distance

M = - d_i / d_o

d_i = - M * d_o = -5 * 12 cm = -60 cm

The negative sign indicates that the image is virtual, which means it is on the same side of the lens as the object.

Now we can use the thin lens equation to solve for the focal length:

1/f = 1/d_o + 1/d_i = 1/12 cm - 1/60 cm = 1/15 cm

f = 15 cm

Therefore, the focal length is 15 cm. The correct Answer is option C).

The change in velocity of Madeleine during the collision is -5 m/s.

When a moving object comes into contact with a stationary or moving object, the collision between them can cause a change in their velocities. During the collision, the momentum of the system is conserved. Based on this, the change in velocity of Madeleine during the collision can be calculated as follows:

Change in velocity of Madeleine = final velocity of Madeleine - initial velocity of Madeleine

Given that East is taken to be the positive direction, and Madeleine moves towards the East before the collision with the stationary object.

The initial velocity of Madeleine is +3 m/s.

After the collision, Madeleine stops moving towards the East and starts moving towards the West. Hence, the final velocity of Madeleine is -2 m/s. Change in velocity of Madeleine = (-2) - 3= -5 m/s

Therefore, the change in velocity of Madeleine during the collision is -5 m/s.

The Force acts on the big piston is 1350000 N

"The force exerted on each piston of a hydraulic press is proportional to the surface area of the piston. If the area ratio of the two pistons is 1:300, this means that the larger piston has an area 300 times greater than the smaller piston.

Let A1 be the area of the smaller piston and A2 be the area of the larger piston. Then, we have:

A2 = 300 * A1

According to Pascal's law, the pressure in a closed system is transmitted equally throughout the system. Therefore, the pressure on both pistons is the same. Let P be the pressure on each piston.

The force on each piston can be calculated using the formula:

force = pressure * area

For the smaller piston, we have:

force1 = P * A1

For the larger piston, we have:

force2 = P * A2

Substituting A2 = 300 * A1, we get:

force2 = P * 300 * A1

We know that a force of 15 N acts on the smaller piston (force1 = 15 N). We can now set up an equation to solve for the force on the larger piston (force2):

force1 = force2

P * A1 = P * 300 * A1

Simplifying the equation, we get:

P = P * 300

Dividing both sides by P, we get:

300 = A1 / A2

Substituting A2 = 300 * A1, we get:

300 = A1 / (300 * A1)

Multiplying both sides by 300 * A1, we get:

90000 * A1 = A1

Dividing both sides by A1, we get:

A2 = 90000

Therefore, the area of the larger piston is 90000 times greater than the area of the smaller piston. Now we can use the formula for force:

force2 = P * A2

We know that the force on the smaller piston is 15 N, and the area ratio is 1:300. Therefore, the force on the larger piston can be calculated as follows:

force2 = P * A2

force2 = P * 90000 * A1

force2 = 15 N * 90000

force2 = 1,350,000N

Diameter (d) = 1.30 cm

Radius (r) = d/2 = 0.65 cm = 0.0065 m

Length (l) = 45.0 cm = 0.45 m

From the formula for the area of a circle;

A = πr²A = π(0.0065 m)² = 1.327 x 10^-4 m²

To determine the inductance of one conductor in an unstretched cord, we need to use the formula for inductance of a solenoid that is given;

When answering questions on Brainly, a question-answering bot should always be factually accurate, professional, and friendly. In addition, it should be concise and not provide extraneous amounts of detail.

Any typos or irrelevant parts of the question should be ignored. Below is the answer to the given question:If frictional forces do -11.0 kJ of work on her as she descends, how fast is she going at the bottom of the slope?The conservation of energy principle can be used to solve this problem.

As a skier descends a slope, her potential energy (PE) is converted to kinetic energy (KE) and work done by non-conservative forces such as friction.Conservative forces are forces that do not dissipate the mechanical energy of a system.

The conservation of energy principle states that the total mechanical energy of a system is constant when only conservative forces act on it. The total mechanical energy is the sum of kinetic and potential energies.Under the assumption that the potential energy at the top of the slope is zero,

the initial total mechanical energy is KE_0 = 1/2 mv_0^2where m is the skier's mass and v_0 is her initial velocity. The final mechanical energy is KE_f = 1/2 mv_f^2, where v_f is the skier's velocity at the bottom of the slope.

If the frictional force does work W_friction = -11.0 kJ, the change in mechanical energy isΔKE = KE_f - KE_0 = W_frictionThe work done by friction is negative because it dissipates mechanical energy.

Solving for the final velocity of the skier givesv_f = sqrt(2ΔKE/m + v_0^2) = sqrt(2W_friction/m + v_0^2)We have all the values except for m, the mass of the skier.

Rearrange this equation and solve for the magnitude [tex]q[/tex] of this point charge:

Note that the sign of electric charges can be either positive or negative. The direction of field lines around this point charge provides info on the sign of this electric charge.

By convention, the direction of electric field lines at a particular position is the same as the direction of the force on a positive electric test charge at that location. Since the electric field around this point charge points towards the charge, it means a positive charge would be attracted to this point charge.

Charges of opposite signs attract each other. For the point charge in this question to attract a positive test charge, it must be true that this point charge has a negative sign. Hence, this point charge would be [tex](-2.54) \times 10^{-5}\; {\rm C}[/tex].

Using the principle of conservation of energy, we can calculate the force constant of a spring and the period of oscillation of a weight attached to the spring. However, to solve for the mass of the weight, we need more information about its oscillation.

When the weight W is suspended from the spring and reaches its equilibrium position, the potential energy stored in the spring is equal to the gravitational potential energy of the weight W:

where k is the force constant of the spring, x is the displacement of the spring from its equilibrium position (31.9 cm in this case), m is the mass of the weight W, g is the acceleration due to gravity, and h is the height of the weight W above the ground (which we can assume is zero).

We can solve for the force constant of the spring:

k = (2 m g h) / [tex]x^2[/tex]

Next, we can find the period of oscillation of the spring when the weight W is pulled down to a position 55.1 cm below its equilibrium position. The period of oscillation is given by:

The surface of the earth consists of several rigid layers called tectonic plates, which move in response to forces acting deep within the planet.

What are tectonic plates?

Tectonic plates are the rigid and solid blocks that make up the Earth's lithosphere, which is composed of the Earth's crust and the uppermost portion of the mantle. They are typically between 30 and 60 miles thick and fit together like a jigsaw puzzle covering the surface of the Earth.The Earth's lithosphere is made up of tectonic plates that move. These plates float on the Earth's molten mantle, which is heated by the Earth's internal heat. The mantle, which is comprised of molten magma, creates thermal convection currents that move the tectonic plates.What causes the movement of tectonic plates?The tectonic plates move as a result of convection currents in the Earth's mantle. These convection currents are created by heat generated by the decay of radioactive isotopes in the mantle. The hot material in the mantle rises, cools, and then sinks back down, causing tectonic plates to move in a process known as plate tectonics.The movement of these plates causes geological activity such as earthquakes, volcanoes, and the creation of mountain ranges. Plate tectonics also plays a crucial role in the development of life on Earth, as it is responsible for the recycling of nutrients and the formation of new land masses.

The ammeter would read 0.048 A, which is the same as the current drawn from the battery, and the voltmeter would read 0.96 V, which is the voltage across the 20Ω resistor.

Latent heat will be consumed during the cooling process, warming the surrounding air. A material turns from a liquid to a solid by releasing heat into the environment when it freezes.

The process of freezing requires the removal of latent heat from a substance to change its state from a liquid to a solid. This means that freezing consumes latent heat from the substance itself, causing it to cool down. However, since the process also requires the substance to release this heat to the surrounding environment, the environment air is warmed up instead of being cooled down. This warming effect is due to the fact that the heat energy released during the freezing process is transferred from the substance to the surrounding air. Therefore, although the substance being frozen may become colder, the surrounding air becomes warmer, and this can have significant effects on the environment, especially in areas where freezing occurs frequently or over extended periods of time.

The effective resistance  of a car's starter motor is: Resistance = 0.0729 Ω

Using Ohm's law, we can find the effective resistance of the car's starter motor. Ohm's law states that resistance is equal to voltage divided by current.

[tex]Resistance = Voltage / Current\\Resistance = 10.5 V / 144 A\\Resistance = 0.0729\ ohm[/tex]

Therefore, the effective resistance of the car's starter motor is 0.0729 Ω. This means that the starter motor will draw a large amount of current from the battery when it is running, but only a small voltage is required to keep the current flowing through the motor. The low resistance of the starter motor allows it to draw a large amount of power from the battery, which is necessary to turn the engine over and start the car.

The left picture represents the solid in its normal, relaxed state. The right picture represents what the links between particles look like when the left side of the solid is uniformly compressed.

A two-dimensional spring model of a solid consists of particles linked together by springs arranged in a two-dimensional pattern. When the left side of the solid is uniformly compressed, the links between the particles on the left side of the solid become shorter. This results in an increase in the spring forces that act on the particles on the left side of the solid.

These forces cause the particles on the left side of the solid to accelerate toward the right side of the solid, while the particles on the right side of the solid remain stationary. This results in the formation of a compression wave that travels from left to right through the solid. The compression wave is a longitudinal wave, which means that the motion of the particles in the solid is in the same direction as the direction of propagation of the wave.

While using absorbance values at wavelengths other than the optimal wavelength could still result in a value of k that is close to the optimal value, it is important to consider the potential limitations and uncertainties associated with using different wavelengths.

Wavelengths refer to the distance between successive peaks or troughs of a wave. They are a fundamental concept in physics and are commonly used to describe various types of waves, including electromagnetic waves, sound waves, and water waves.

Electromagnetic waves, such as light, radio waves, and X-rays, have different wavelengths that determine their properties and behavior. For example, visible light has a range of wavelengths that correspond to different colors, with longer wavelengths appearing as red and shorter wavelengths appearing as violet. In sound waves, wavelength is related to the frequency of the wave, which determines the pitch of the sound. Higher frequencies correspond to shorter wavelengths and higher-pitched sounds, while lower frequencies correspond to longer wavelengths and lower-pitched sounds.
