Sound needs medium to travel and it can not travel without medium
so sound wave is a travelling wave
now we also know that sound wave propagate in form of rarefaction and compression.
So all medium particles travel in the direction of wave only
so it is a longitudinal wave also
so correct answer will be
<em>mechanical longitudinal </em>
Answer:
1.70 J
Explanation:
The heat dissipated is the difference in the kinetic energies.
This is given by

and
are the initial and final velocities.
With <em>m</em> = 0.175 kg,

The negative sign appears because energy is lost.
A. Solid
Solid structures are actually made of repeating patterns.
Answer:
Hydroelectricity
Explanation:
There are varipus situations in which mechanical energy is turned into electrical energy for use but the most common is in hydroelectricity.
The attachment will give a better understanding pf how this works.
Answer:
Hacksaw blade because it is metal.
