Answer:
Sound energy wave is transferred through a substance as a series of compressions.
Explanation:
Sound is caused by regular oscillating that produce regions of compression (high pressure) and rarefaction (low pressure) that move through a substance. Sound not only travels through air, it can travel through any substance, solid, liquid or gas. Whales can hear other whales across whole oceans through water, an Earthquake is low frequency sound moving through the solid Earth
A vibrating object compresses the air and sound waves move from the source, much like waves in water if you drop a stone into it. These sound waves can carry great distances depending on their loudness and frequency.

Explanation:
As we know that the net torque on the wheel is given as
now we know that its angular speed changes from 0 to 10 rad/s in time interval of 6.00 s
so we have
Part a)
We know that the relation between torque and angular acceleration is given as
Part b)
Now the angular speed will reduce to zero after removing external torque in t = 60 s
now we have
so frictional torque is given as
Part c)
Number of revolutions are given by the equation
