Question

what type of energy transfer occurs when a helicopter is flying in the air? the nuclear energy from the fuels is transformed into electromagnetic and electrical energy. the electrical energy from the fuels is transformed into solar and nuclear energy. the chemical energy from the fuels is transformed into mechanical and sound energy.

Explanation:

When a helicopter is flying, fuel is burned. The chemical energy in the fuel is released through combustion. This energy is then used to power the engines and rotors, resulting in mechanical energy for flight and also producing sound energy.

Answer:

The chemical energy from the fuel is transformed into mechanical and sound energy.
