When a ball rises vertically to a height h and returns to its original point of projection the work done by the gravitational force is?

The work done would be calculated by 2mgh.
The force on the ball is calculated by mg, and work done is by Fd, where d is 2h (the force acts on both upwards height and downwards height, thus twice the distance).

A ball thrown vertically upward returns to the starting point in 8 seconds.find its initial velocity.?
A ball thrown vertically upward returns to the starting point in 8 seconds.-- Its velocity was upward for 4 seconds and downward for the other 4 seconds.-- Its velocity was zero at the turning point, exactly 4 seconds after leaving the hand.-- During the first 4 seconds, gravitational acceleration reduced the magnitude of its upward velocity by(9.8 meters/second2) x (4 seconds) = 39.2 meters per second-- So that had to be the magnitude of its initial upward velocity.
Why does energy stored in deformed material in only its elastic portion?
The "elastic portion" is precisely the part where the material returns to its original shape, and thus returns its energy. Once the material does NOT return to its previous shape, it doesn't exert a force back to the original position, and there is no way to get the energy back.
Is it true that When you apply a force an object it deforms for a while then returns to its original shape?
On a very small scale, it is true.
What material returns to its original shape when a load is removed?
An elastomer, which is also called "a rubber" but most elastomers contain no rubber.
In throwing a ball upward discuss the velocity and acceleration when the ball returns to the thrower's hand?
A the moment when the ball just touches the thrower's hand, it will have the velocity with which it was thrown and the acceleration will be equal to the acceleration due to gravity at the place acting vertically downwards.
What is the null join?
The join which does not fetch any result that is it returns null value after projection operation is called null join
