The amount of energy a sound wave carries per second through a unit area is its

intensity

Which type of wave has a trough and crest

Transverse Waves

In which part of truck the free vibration occur

This question is missing a massive amount of background info required to answer.

Does sound go through solids quicker than liquids or gases

This will not answer the question; however sound does not travel thru solids, as sound waves travel only thru gases or air.

Why at a constant speed if an object changes its direction it is considered to be acceleration

Acceleration is a direction plus a speed. If either changes then the acceleration changes.

Do you measure sound in hertz

Hertz (cycles/second) measures frequency or pitch. Decibels measures loudness or sound pressure.

When an apple falls from a tree and strikes the ground without bouncing what happens to its momentum

It's transferred to the Earth

Will a sound wave move faster in winter

No it will move slower. Waves move faster in warm air and slower in cold air.

A disturbance that travels through a medium as a longitudinal wave is

Sound wave.

What correction should be made to the following The air was cold but the sun was hot

chance but for and ,the air was cold and the sun was hot?

If a tree falls down on to the ground and nobody is around does it make a sound

yes. just not audible.

What is the speeD of a wave traveling with a frequency of 5 hz an a wavelength of 3cm

Speed = (frequency) x (wavelength) = (5) x (3 cm) = 15 cm/sec

Who flew in first supersonic fight in 1947

Chuck Yeager flew the Bell X1 to break the sound barrier in 1947


Chuck Yeager flew the Bell X1 to break the sound barrier

How do particles move when a mechanical wave passes through them

the particles of the medium just vibrate, or move back and forth or up and down in one spot

In which medium does sound move the slowest

The less dense the medium the slower the propagation of sound.

The more rigid the medium the faster the propagation of sound.

How does light waves compare with sound waves

Light waves are electromagnetic waves that move at the speed of light. Sound waves are compression waves that move through a medium (air, liquids, solids), with varying speeds according to the medium.
