Answer:
The Starship Enterprise is powered by combining matter with antimatter.

Answer: buzzer.
The working principle of a buzzer is the conversion of electrical energy to sound energy.
The switch just cuts or permits the flow of current, the motor convertes electrical or other kind of energy into mechanical energy, a bulb converts electrical energy into light and a battery converts chemical energy into electrical energy.
Answer:
volume
Explanation:
Identical size means volume will be the same in each calculation of
density = mass / <u>volume</u>
