A thermodynamic system is taken from an original state to an intermediate state by the linear process shown in Fig. (12.13) Its volume is then reduced to the original value from E to F by an isobaric process. Calculate the total work done by the gas from D to E to F :

In changing the state of a gas adiabatically from an equilibrium state A to another equilibrium state B, an amount of work equal to 22.3 Jis done on the system. If the gas is taken from state A to B via a process in which the net heat absorbed by the system is 9.35 cal, how much is the net work done by the system in the latter case ? (Take 1 cal = 4.19 J)

A force F acting on the object varies with distance x as shown in fig.The force is in N and x is in m.The work done by the force in moving the object from x =0 to x=6 m is : .

An ideal gas undergoes isothermal process from some initial state I to final state f. choose the correct alternatives

Consider a PV-diagram in which the path followed by one mole of perfect gas a cylindrical container is shown in (fig.). Find the work done when the gs is taken from state 1 to state 2.

A given mass of gas expands from state A to state B by three paths 1,2 , and 3 as shown in the figure below. If w_(1),w_(2) and w_(3) , respectively, be the work done by the gas along three paths, then

The output E of an alternating voltage supply of frequency 50 Hz is shown in Fig. From this Fig, state root mean square voltage E_(v)

A storage battery of a car has e.m.f of 12 V. The maximum current that can be drawn from the battery is 24A. Calculate the internal resistance of the battery.

A magnet is suspended vertically from a fixed point by means of a spring, as shown in the figure. One end of the magnet hangs inside a coil of wire. The coil is connected in series with a resistance R. The magnet is displaced vertically a small distance D and the released. shown in the figure variation with time t of the vertical displacement d of the magnet from its equilibrium position. State and explain, by reference to electromagnetic induction, the nature of the oscillations of the magnet. Calculate the angular frequency omega_0 of the oscillations.
