Answer:
Explanation:
The formula P=VI, just rearrange to find I
So
I=P/V
=75/120
=0.625amps
625mA

D.sound insulators prevent from being transmitted better than elastic solids
Explanation:
The correct option from the given choices is that, sound insulators prevent sound from being transmitted better than elastic solids.
Sound is a form of wave that transmits energy from one point to another.
This wave form is a longitudinal wave in nature.
During the propagation of sound, it requires a material medium to move.
Sound insulators are special materials designed not to transmit sound energy.
Such materials cuts off sound. They are better than elastic solids in preventing sound transmission.
