To know more about the effects of doubling the radius of a wheel and solve the given problem:

When the radius of a wheel is doubled, the answers to the given questions are affected in the following ways:

The angular speed at 2.00 s is smaller: False. Doubling the radius does not directly affect the angular speed at a specific time. It depends on the angular acceleration and initial conditions.

The angle rotated through from t = 0 to t = 2.00 s is the same: True. The angle rotated depends on the angular speed and time, which are not directly affected by the radius.

The angular speed at t = 2.00 s is greater: False. The angular speed is not affected by doubling the radius, assuming the angular acceleration remains constant.

The angular speed at t = 2.00 s is the same: True. Doubling the radius does not directly impact the angular speed at a specific time, assuming other factors remain constant.

The angle rotated through from t = 0 to t = 2.00 s is greater: False. The angle rotated depends on the angular speed and time, which are not directly influenced by the radius.

The angle rotated through from t = 0 to t = 2.00 s is smaller: False. The angle rotated depends on the angular speed and time, which are not directly affected by the radius.

Now, let's solve the provided problem. We are given that the wheel has a constant angular acceleration of 3.40 rad/s² and an angular speed of 1.70 rad/s at t = 0.

(a) To find the angle rotated between t = 0 and t = 2.00 s, we can use the equation: θ = ω₀t + (1/2)αt², where ω₀ is the initial angular speed, α is the angular acceleration, and t is the time. Substituting the given values, we get θ = (1.70 rad/s)(2.00 s) + (1/2)(3.40 rad/s²)(2.00 s)². Evaluating this expression gives us the angle rotated in radians.

(b) To find the angular speed at t = 2.00 s, we can use the equation: ω = ω₀ + αt. Substituting the given values, we get ω = 1.70 rad/s + (3.40 rad/s²)(2.00 s).

(c) To find the angular displacement in revolutions when the angular speed doubles, we need to find the angular speed when t = 2.00 s and then double that value.

Answer:

Elephant and the eath because Fg is determined by Mass of an object.. So elephant has greater mass therefore, it's Fg is higher

According the universal  law of gravitation, the gravitational force is directly proportional to the mass of an object.  An elephant weighs so much than a man and thus it will experience larger gravitational force from earth.

Gravitational force is a resistive force by which an object attracts other objects towards its centre of mass. The force exerted by the object depends on the mass and the force experienced by the other object depends on its mass and distance between the two objects.

According to universal law of gravitation, the gravitational force is directly proportional to the mass of the object and distance from the ground. The expression for the law is written as:

\(\rm g = G \frac{M_{1} M_{2}}{r^{2}}\)

Where, G is the universal gravitational constant and M1 and M2 be the masses of two objects which and r be the distance between them. As per this relation gravity decreases with increase in distance and increase with an increase in mass.

Therefore, a massive body such as an elephant will experience greater gravitational force from the earth.

The planetary body with the fastest orbit is Mercury, and the one with the slowest orbit is Neptune.

There is a general pattern between orbital velocity and orbital radius known as Kepler's second law of planetary motion. According to this law, a planet sweeps out equal areas in equal times as it orbits the Sun. This implies that planets closer to the Sun have smaller orbital radii and must travel faster to cover the same area in the same amount of time.

The relationship between orbital velocity and orbital radius can be expressed as v ∝ 1/r, where v represents the orbital velocity and r denotes the orbital radius. This relationship shows that as the orbital radius increases, the orbital velocity decreases. In other words, planets farther from the Sun have slower orbital velocities compared to those closer to the Sun.

This pattern is consistent with observations in our solar system. The inner planets, such as Mercury, have smaller orbital radii and faster orbital velocities, while the outer planets, like Neptune, have larger orbital radii and slower orbital velocities.

1. The intrinsic brightness of a star is also known as its absolute magnitude. This magnitude measures the actual amount of light that a star emits.
2. The intrinsic brightness of a star is independent of its distance from Earth. This means that even if a star is far away, its intrinsic brightness remains the same.
3. The intrinsic brightness of a star can be determined by measuring its apparent magnitude and knowing its distance from Earth. The apparent magnitude is how bright a star appears to us from Earth, while the distance is the actual physical distance between the star and Earth.
4. The intrinsic brightness of a star can be used to classify stars into different types or spectral classes. For example, stars with high intrinsic brightness are classified as "supergiants," while stars with low intrinsic brightness are classified as "dwarfs."
5. The intrinsic brightness of a star can vary greatly from star to star. Some stars are much brighter than others due to factors like their size, temperature, and age.
6. The intrinsic brightness of a star can be calculated using the formula: Intrinsic Brightness = (Apparent Brightness * 4π * (Distance)²) / (Luminosity Constant)
The intrinsic brightness of a star, also known as its absolute magnitude, is a measure of the actual amount of light that a star emits. It is important to note that the intrinsic brightness of a star is independent of its distance from Earth. This means that even if a star is far away, its intrinsic brightness remains the same.

However, in order to determine the intrinsic brightness of a star, we need to measure its apparent magnitude (how bright it appears to us from Earth) and know its distance from Earth. The apparent magnitude is measured on a logarithmic scale, with smaller numbers indicating brighter stars. By comparing the apparent magnitude and distance of a star, we can calculate its intrinsic brightness using the formula: Intrinsic Brightness = (Apparent Brightness * 4π * (Distance)²) / (Luminosity Constant).

The factors that can change the pattern observed on a screen during Young's double-slit experiment are given below:

1. Width of the slit. The width of the slit can influence the diffraction pattern that is observed on a screen. When the width of the slit decreases, the central maximum of the diffraction pattern becomes broader, and the intensity of the secondary maxima reduces.

2. Distance between slits. The distance between the slits in the double-slit experiment also affects the pattern on the screen. The distance between the slits is equal to the spacing between the maxima. If the spacing between the slits decreases, the distance between the maxima decreases, and vice versa.

3. Distance between slits and screen. The distance between the slits and the screen is also a factor that can affect the diffraction pattern. When the distance increases, the spacing between the maxima becomes wider, and the intensity of the maxima decreases.

4. Wavelength of the incident light. The wavelength of the incident light is another factor that affects the diffraction pattern on the screen. When the wavelength increases, the spacing between the maxima increases, and vice versa.

5. Refractive index of the medium. The refractive index of the medium in which the light travels can also influence the diffraction pattern observed on a screen.

When the refractive index of the medium changes, the position of the maxima changes as well. These are the factors that can change the pattern observed on a screen during Young's double-slit experiment.

Answer:

DDDD

Explanation:

To solve this problem, we can use the equations of motion and Newton's second law of motion. The equation of motion for an object moving at constant speed is:

x = x0 + v0t + (1/2)at^2

where x is the final position, x0 is the initial position, v0 is the initial velocity, t is the time, and a is the acceleration.

In this case, the initial position is 0 m (since the crate starts at the beginning of the 12 m distance), the initial velocity is 0 m/s (since the crate starts at rest), and the time is 12 s (since the crate moves at a constant speed of 1.50 m/s).

We can use these values to solve for the acceleration:

12 m = (1/2)(a)(12 s)^2

a = 0.5 m/s^2

Now that we know the acceleration, we can use Newton's second law of motion to find the normal force:

F = ma

N = (20 kg)(0.5 m/s^2)

N = 10 N

This is the magnitude of the normal force on the crate. Note that this is the normal force exerted by the floor on the crate, not the force of tension in the rope. To find the force of tension in the rope, we would need to consider the angle of the rope and the direction of the force.
