Electricity
b) Light - the original form of the energy could have been potential energy stored in an atom or molecule before being released as kinetic energy in the form of light when the subatomic particle moves.
The idea is that when you convert energy from one form to another (for example, from form "A" to form "B"), the amount of energy of form "A" decreases; the amount of energy of form "B" increases; but the total of both doesn't change.
Solar energy is energy from the sun that is converted into electricity using solar panels, while heat energy is the total amount of kinetic energy due to the motion of molecules in a substance. Solar energy harnesses the sun's rays to create electricity, while heat energy is a form of energy associated with the temperature of an object or substance.
B. Wilkins has written: 'Electricity tariffs and the 1983 Energy Act'
Sound energy can be stored in elements such as air, water, and solids like metal or wood. These elements can vibrate when sound waves pass through them, storing and transmitting the sound energy in the process.
b
A is wrong. B is right C is right D is wrong A: Sound travels as a wave, therefore it does not travel in a straight line. B: Sound travels in a wave. C: The sound wave is a form of energy; all waves are. D: Sound cannot travel in a vaccuum. A is not entirely wrong.
B wind- Wind energy is considered kinetic energy due to the movement of air molecules. This kinetic energy can be harnessed to produce mechanical energy through wind turbines and also electricity through generators.

See, I even put the subscripts!Well it will I just answered your question.
a: it is an energy efficient way of getting electricity B: do not forget all the waste we will get rid of by doing this
By means of devices known as "microphone" or "telephone".
What makes electricity useful is that it is relatively easy to (a) transfer it over large distances, and (b) convert back and forth with other forms of energy.
