Which best describes the way a sound wave is sent through the radio?

a: sound wave → radio wave

b: radio wave → sound wave

c: sound wave → electrical signal → radio wave → sound wave

C: sound wave → electrical signal → radio wave → sound wave

Explanation:

In the radio, Sound waves are first converted into electrical signals. These electrical signals are then sent to the radio via radio waves transmitters. The radio waves are received by the radio devices and these waves are then again converted into sound waves.

Hence the sequence for radio waves transmissions are sound wave → electrical signal → radio wave → sound wave .

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.
