One mole of an ideal gas is taken from state A to state B by three different processes, (i) ACB (ii) ADB (iii) AEB as shown in the P-V diagram. The heat absorbed by the gas is 

An elastic string of unstretched length L and force constant k is stretched by a small length x. It is further stretched by another small length y. The work done in the second stretching is
An elastic string of unstretched length \(L\) and force constant \(k\) is stretched by a small length \(x\). It is further stretched by another small length \(y\). The work done in the second stretching is:
One mole of \(O_2\) gas having a volume equal to \(22.4 \text{ litres}\) at \(0^\circ C\) and 1 atm is compressed isothermally so that its volume reduces to \(11.2 \text{ litres}\). The work done in this process is:
A small block of mass \(m\) is kept on a rough inclined surface of inclination \(\theta\) fixed in an elevator. The elevator goes up with a uniform velocity \(v\) and the block does not slide on the wedge. The work done by the force of friction on the block in time \(t\) will be:
A thermodynamic system is changed from state \( (P_1, V_1) \) to \( (P_2, V_2) \) by two different processes, the quantity which will remain same will be –

A sample of ideal monoatomic gas is taken round the cycle ABCA as shown in the figure. The work done during the cycle is: 

The potential energy for a force field is given by U(x,y) = (x+y). The force acting on a particle at position given by coordinates (0, π/4) is:
A long string is stretched by 2 cm and the potential energy is V. If the spring is stretched by 10 cm, its potential energy will be
