Kinetic energy is formed when water is heated.
Explanation:
- Suppose in an electric kettle there is water , when water is boiled the electrical energy changes into thermal energy when heating is done.
- The thermal energy then gets transferred to the water . When the boiling takes place in the water the energy gets transformed into sound.
- Lastly at the end the gravitational potential energy finally changes to the kinetic energy.
Answer:
D, maintain a constant velocity until acted on by another force
Explanation:
Light bulbs, think about parallel circuits as something you plug into, so for example you plug in a tv for it to work, same with a refrigerator and Christmas lights
1 would use less energy. Please vote my answer brainliest! Thanks.
Answer:
Explanation:
Energy = volt x charge
= 12 x 750000 J
= 9000,000 J
Latent heat of vaporisation
= 2260000 J / kg
kg of water vaporised
= 9000,000 / 2260000
= 3.982 kg .
