(ii) electrical energy
PLEASE HELP ME MATES...
Answers
Explanation:
(a) AMOVING BALL due to motion possesses KINETIC ENERGY.
3 (b) A stone at rest on the top of a building possesses POTENTIAL ENERGY, ∴ Due to height above ground.
3.We will be primarily discussing energy as it is stored in a spring when it is stretched here; however, the same physics would apply for a spring when it is compressed. As you have probably noticed from the above header, spring potential energy is also called elastic potential energy.
4.Energy has many forms, such as light, heat, electricity, chemical energy (stored in chemical bonds) and mechanical energy (moving matter, such as flowing water). ... The first main kind of energy is kinetic energy, the energy of motion and action.
d Chemical energy storage: electrical energy stored in the form of chemical energy. Fuel cell: This is an electrochemical cell that converts the chemical energy from a fuel into electricity through an electrochemical reaction of a hydrogen-containing fuel with oxygen or another oxidizing agent.☺️
Answer:
a moving cricket ball
Explanation:
because a moving object has a energy called kinetic energy
