When a small block is suspended at the lower end of an elastic steel wire hanging form the celling, there is a loss in gravitational potential energy `(U)` of earth-block system then

When a metal wire elongates by hanging a load on it, the gravitational potential energy is decreased.

When a metal wire elongates by hanging a load on it, the gravitational potential energy is decreased.

A body of mass M is attached to the lower end of a metal wire, whose upper end is fixed. The elongation of the wire is l. a) Loss in gravitational potential energy of M is Mg l b) The elastic potential energy stored in the wire is Mgl c) The elastic potential energy stored in the wire is 1/2 Mgl d) Heat produced is 1/2 Mgl

A wooden block of cross sectional area A (in shape of a rectangle) has height h. It is held such that its lower surface touches the water surface in a wide and deep tank. The block is released in this positon. It oscillates for some time and then settles into its equilibrium positon. in equilibrium the block floats with its upper face just on the water surface. Calculate the amount of heat generated in the process assuming that the loss in gravitational potential energy of the system coprising of water and the block gets converted into heat. Density of water is rho .

A body of mass M is attached to lower end of a metal wire whose upper End is fixed. The elongation is l. The ratio of loss of gravitational potential energy to the energy stored in the wire is

When a metal wire elongates by hanging a load on it, the gravitational potential energy is decreased. What does that mean?

One end of an unstretched vertical spring is attached to the ceiling and an object attached to the other end is slowly lowered to its equilibrium position. If S is the gain in spring energy and G is the loss in gravitational potential energy in the process, then
