Working of the IC 7805 do?

A: It s a voltage regulator the 8 indicates a positive regulator the 05 indicates the voltage output. at 1 amps if adequate heat sink is provided. Never fear it has thermal protection to shut it down only if the internal heating exceed the safety zone. It will not destroy itself by removing or reducing the load it will come back alive after cooling

What is critical velocity in fluid flow?

The flow of a liquid remains steady or orderly only so long as its velocity does not exceed a certain limiting value for it, called critical velocity.


Can phase velocity exceed the speed of light?

Yes it can, because the phase velocity of a matter wave does not carry information, and thus does not violate special relativity. The group velocity is what is limited by c.

What is the affect?

It is a method in which you accelerate towards a large gravitational force (usually a planet), which then also accelerates you further and you exceed the velocity necessary to break away from it gravitational field of the object, so you get a velocity boost

Since it also hav gravity..Why moon has no air in it?

As the moons gravity is comparatively weak the escape velocity from the moon is much lower. The speed of the gasses would exceed this velocity and therefore escape to space. There are of course other factors that effect these matters.


Does an explosion create a shock wave?

Almost always, if the velocity of the expanding gases exceed the velocity of sound in that medium you will have a sonic boom. But even if you merely pop a paper bag, there will be a small shock wave as the air pressure dissipates to become equal with the surroundings.
