Answer:

C. the ability to withstand stress

Explanation:

The strength of a material refers to its ability to withstand stress. Stress is a measure of the force applied to a material, and it can be either tensile (stretching) or compressive (squeezing). A material's strength is typically measured by its ability to resist deformation or failure under a given amount of stress.

160 Hz is the higher harmonics of a string fixed at both ends that has a fundamental frequency of 80 Hz.

According to this option c) is correct answer.

A string's fundamental frequency, succeeding frequencies, and two ends are defined as the sum of the entire depending on the number of harmonics. In other words, higher harmonics specify the frequencies that follow under the functions 2f, 3f, 4f, 5f, etc.

As a result, the higher harmonics would be:

1 x 80 Hz Equals 80 Hz (1st harmonic and Fundamental Frequency)

2 × 80Hz Equals 160Hz (2nd harmonic) (2nd harmonic)

3 x 80Hz Equals 240Hz (3rd harmonic)

4 × 80Hz = 320Hz (4th harmonic)

Answer:

approximately 1.007 * 10^8 m/s^2

Explanation:

To find the ball's centripetal acceleration, we can use the formula a = v^2 / r, where a is the centripetal acceleration, v is the tangential velocity of the ball (the speed at which it moves around the circle), and r is the radius of the circle (the length of the piece of string).

First, we need to find the tangential velocity of the ball. The ball makes 159 complete turns each minute, which means it makes 159 * 2 * pi = 998.46 radians per minute. Since the ball is moving at a constant speed, the tangential velocity is equal to the angle it travels in radians per unit of time, so the tangential velocity of the ball is 998.46 radians per minute.

Next, we need to find the radius of the circle. The length of the piece of string is 0.735 m, and since the ball is swinging in a horizontal circle, the radius of the circle is equal to the length of the piece of string. Therefore, the radius of the circle is 0.735 m.

Now that we have the tangential velocity and the radius of the circle, we can plug these values into the formula to find the centripetal acceleration:

a = v^2 / r

= 998.46^2 / 0.735

= 1.007 * 10^8 m/s^2

Therefore, the ball's centripetal acceleration is approximately 1.007 * 10^8 m/s^2.

Answer:

The wave phenomenon that you are describing is known as the Doppler effect. The Doppler effect occurs when a wave, such as a sound wave, passes by an observer and the pitch of the wave seems to change. This is because the frequency of the wave changes as it moves closer to or farther away from the observer. The pitch of a sound wave is directly related to its frequency, so when the frequency of the wave changes, the pitch will also change. This effect is commonly observed with sound waves, but it can also occur with other types of waves, such as light waves.
