Physics Questions

The transport phenomenon occurs only in equilibrium state of a gas and is irreversible.

When the resistance of the air between breaks down the current flows from the positive cloud to the negative cloud in a flash which we call lightning . The difference of potential involves is very high.

In nuclear physics, nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts (lighter nuclei). The fission process often produces free neutrons and releases a very large amount of energy.

Thus, The Nuclear Fission is caused by the impact of Neutrons.

Gasoline is a colorless petroleum-derived flammable liquid that is used primarily as a fuel in spark-ignited internal combustion engines. It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives. It is also called as Petrol. It has chemical potential energy, in combustion it is turned into light, sound, heat and kinetic energy.

This 11.2 km/s is also known as the escape velocity. It works out to roughly 25000miles per hour 

Materials that allow electricity to flow are called electrical conductors and that materials which does not allow electricity to flow are called Insulators.
