If a compressed spring is dissolved in acid, what happens to the elastic potential energy of the spring ?

"A mass is attached to one end of a spring and by holding the other end in hand, the spring is whirled in a horizontal circle" What happens to the length of the spring ?

A compressed spring of an air gun has kinetic energy.

In figure, k = 100 N//m, M = 1kg and F = 10 N (a) Find the compression of the spring in the equilibrium position (b) A sharp blow by some external agent imparts a speed of 2 m//s to the block towards left. Find the sum of the potential energy of the spring and the kinetic energy of the block at this instant. (c) Find the time period of the resulting simple harmonic motion. (d) Find the amplitude. (e) Write the potential energy of the spring when the block is at the left estreme. (f) Write the potential energy of the spring when the block is at the right extreme. The answers of (b), (e) and (f) are different. Explain why this does not violate the principle of conservation of energy ?

Two masses m and 2m are attached to two ends of an ideal spring as shown in figure. When the spring is in the compressed state, the energy of the spring is 60 J, if the spring is released, then at its natural length

Answer the question briefly and to the point: What will happen to the potential energy of the atoms of a solid when compressed? On stretching a wire ?

A block is fully submerged in a vessel filled with water by a spring attached to the bottom of the vessel. In equilibrium position spring is compressed. If the vessel now moves downwards with an acceleration a(lt g) . What happens to the length of the spring.?

A spring is kept compressed by a small trolley of mass ring 0-5 kg lying on a smooth horizontal surface as shown in the adjacent Fig. When the trolley is released, it is found to move at a speed = 2 m s^(-1) . What potential energy did the spring poses when compressed?

A force of 10 N holds an ideal spring with a 20 N/m spring constant in compression. The potential energy stored in the spring is

A block of mass m is initially moving to the right on a horizontal frictionless surface at a speed v. It then compresses a spring of spring constant k. At the instant when the kinetic energy of the block is equal to the potential energy of the spring, the spring is compressed a distance of :
