A sound wave is produced in a metal cylinder by striking one end. Which of the following occurs as the wave travels along the cylinder?
a. Its frequency increases
b. It transfers matter
C. It transfers energy
d. Its amplitude increases

C. It transfers energy

Explanation:

As the metal cylinder is strike at one end, energy is being transferred.

A wave is a disturbance that transmits energy from one point to another. All waves are prominent for their energy transfer potentials. Waves do not move materials of the medium. The frequency of the wave does not increases same with the amplitude. The most important thing about a wave is the ability to transmit energy

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
