A three-step cycle is undergone reversibly by 4.00 mol of an ideal gas: (1) an adiabatic expansion that gives the gas 2.00 times its initial volume, (2) a constant-volume process, (3) an isothermal compression back to the initial state of the gas. We do not know whether the gas is monatomic or diatomic; if it is diatomic, we do not know whether the molecules are rotating or oscillating. What are the entropy changes for (a) the cycle, (b) process 1, (c) process 3, and (d) process 2?

A car starting from the rest moves at an acceleration of 2m/s² for 5s. Then it moves with uniform velocity for another 5s. After that it starts to decelerate and comes to the rest in 10s..
(i) Draw the velocity vs time graph for the car from the above data.
(ii) Draw the displacement vs time graph for the same.
Please help me answer the following question!
A solid cylinder of length L and radius R is coaxial with the z-axis with one circular end at z= 0 and the other at z = L. The cylinder material contains microscopic magnetic dipoles, which have average magnetic dipole moment <m> and number density n(r) given by
<m> = m0 ez, n(r) = n0(1-(z/L))a
in cyclindrical coordinates. If m0, n0, and a are real constants, what is the bound surface current ib on each surface and the total current I due to bound surface currents?
