Physics Questions

Magnetism in materials is due to circular motion of electrons.

Any moving object can exhibit kinetic energy, as kinetic energy is also known as Motional energy.

In the given options, only a space station orbiting Earth is in motion and all the other are in rest position.

Hence, option C) a space station orbiting Earth is only exhibiting kinetic energy.

Nuclear Power Plant uses a Non Renewable Energy Source.

Non-renewable energy is that source of energy which can not be used again and again. This sort of energy is sustainable to exhaustion.

Non renewable energy is that form of energy which is subject to deletion. This type of energy is of many uses to us. It can be used to produce electricity, heating, cooking, transportation and manufacturing. 85% of the energy used in the industrial processes is form the non-renewable type of energy.

Analog synthesis uses a mixture of complex sounds that are shaped by filtering. It is based on representing data in terms of measurable physical quantities, in this case sound waves.

The device which is used to measure air pressure is called as barometer. If the barometer reading is rising, it indicates that the air pressure is increasing and if the reading is falling the air pressure is decreaing.

A compressor is a mechanical device that increases the pressure of a gas by reducing its volume. An air compressor is a specific type of gas compressor. The capacity of the air conditioning depends entirely on the capacity of the compressor. The reciprocating compressor is usually used in AC.

The reciprocating compressor have piston and cylinder arrangement like the automotive engine. The reciprocating motion of the piston due to external power compresses the refrigerant inside the cylinder.

There are three types of reciprocating compressors:

hermetically sealed,

semi-hermetically sealed and

open type.

If a micrograph is false-colored, it means that the computer has created the colour for the object since we know that the electron microscopes sees only black and white colours.
