How could i design an experiment to test the speed of sound in different materials such as fabric, cardboard, steel, aluminum, plastic.

Answers

Answer 1

Answer: To design an experiment to test the speed of sound in different materials, you could use a speaker and a microphone to measure the time it takes for sound to travel through each material. First, you would need to set up the speaker and microphone on opposite sides of each material and measure the distance between them. Then, you would play a sound from the speaker and measure the time it takes for the sound to reach the microphone. You could repeat this process for each material and use the data to calculate the speed of sound in each material. Additionally, you could compare your results to the known speed of sound in air (343 m/s) to see how the materials affect the speed of sound.

Explanation:

a sphere rolls down without slip on an inclined plane of inclination theta. what is the linear acceleration as the sphere reaches the bottom

Answers

Answer:When a sphere rolls down an inclined plane without slipping, its linear acceleration at the bottom can be calculated using the following formula:

a = g * sin(theta)

where "a" is the linear acceleration, "g" is the acceleration due to gravity (approximately 9.8 m/s^2), and "theta" is the angle of inclination of the plane.

Let's break down the formula step by step:

1. First, we need to determine the component of the gravitational force that acts parallel to the inclined plane. This component is given by g * sin(theta), where "g" is the acceleration due to gravity and "theta" is the angle of inclination.

2. Since the sphere is rolling without slipping, the frictional force between the sphere and the inclined plane is responsible for its linear acceleration. This frictional force is equal to the component of the gravitational force parallel to the plane.

3. Therefore, the linear acceleration of the sphere as it reaches the bottom of the inclined plane is equal to the component of the gravitational force parallel to the plane, which is g * sin(theta).

For example, if the angle of inclination, theta, is 30 degrees, the linear acceleration of the sphere at the bottom of the inclined plane would be:

a = g * sin(30) = 9.8 m/s^2 * 0.5 = 4.9 m/s^2

So, the linear acceleration of the sphere as it reaches the bottom of the inclined plane would be 4.9 m/s^2 when the angle of inclination is 30 degrees.

Which explains how the Coriolis effect causes air circulation? A.
Air from the equator moves toward the poles faster than the ground below it, so friction causes the air to veer west. In contrast, air from the poles moves toward the equator slower than the ground below it, so friction causes it to veer to the east.
B.
Air from the equator moves toward the poles faster than the ground below it, so friction causes the air to veer east. In contrast, air from the poles moves toward the equator slower than the ground below it, so friction causes it to veer to the west.
C.
Air from the poles moves toward the equator faster than the ground below it, so friction causes the air to veer east. In contrast, air from the equator moves toward the poles slower than the ground below it, so friction causes it to veer to the west.
D.
Air from the equator moves toward the poles slower than the ground below it, so friction causes the air to veer east. In contrast, air from the poles moves toward the equator faster than the ground below it, so friction causes it to veer to the west.

Answers

The right answer for the question that is being asked and shown above is that: "Air from the equator moves toward the poles faster than the ground below it, so friction causes the air to veer west. In contrast, air from the poles moves toward the equator slower than the ground below it, so friction causes it to veer to the east. "
