What piece of apparatus would you use to change sound energy into electrical energy?
A microphone converts sound energy into electrical energy. It does this by capturing sound waves emitted from a source cause movements in a thin metallic diaphragm and an associated coil of wire. A magnetic field is developed around the coil with the help of a magnet and as the coil moves within this field under the effect of the sound waves, it produces an electric current. The amount of current produced depends on the velocity of that motion, so it is velocity sensitive.
Do energy cannot change from one form to other?
Energy in all forms (electrical, mechanical, chemical, thermal) can change from different forms. For example, consider a piece of coal in a power plant. The burning piece of coal is transforms from chemical to thermal energy. If the thermal energy (heat) boils water, it's transform to an another form of chemical energy. Then, if it turns a turbine, it's changed to mechanical energy. Then, finally, the turbine turns a generator and makes electricity (electrical energy).
What piece of apparatus can be used to find the energy content of food?
A calorimeter. Basically you burn food inside a box and then measure the energy you get out of it. You have to make sure that the energy does not get out of the box
Which electrical device converts electrical energy into light what is its symbol?
You may be talking about a lamp which has the symbol ( unable to show ) like symbol omega with a circle . Any piece of metal which heats will emit light
How electrical energy converted into sound energy?
Most commonly by the use of loudspeakers. The electrical current flowing through a coil (thus making a magnetic field), which attracts an iron slug (a solenoid), which is glued to a piece of heavy paper (the diaphragm of the speaker), When the paper moves it compresses air, which we hear as sound.
Which piece of apparatus would you use to change sound energy to electrical energy?
-- a microphone -- the part of a telephone near your mouth
What piece of apparatus would you use to change elastic potential energy into kinetic energy?
Movement
What piece of electrical apparatus is used to change the brightness of a light bulb?
That is called a rheostat or a dimmer.

What are the parts of an bp apparatus aneroid?
The parts of this apparatus include the bladder, aneroid gauge, tubing, and ear piece.
Is it possible for all the energy stored in a piece of coal to turn into usable energy?
Yes. That's what a lot of electrical energy is made of. Coal is burned in to a gas which turns turbine. That then generates usable energy
