A particle is executing simple harmonic motion with a time period of 3 s. At a position where the displacement of the particle is 60% of its amplitude, the ratio of the kinetic and potential energies of the particle is:
The P-V diagram of an engine is shown in the figure below. The temperatures at points 1, 2, 3 and 4 are T1, T2, T3 and T4, respectively. 1→2 and 3→4 are adiabatic processes, and 2→3 and 4→1 are isochoric processes
Identify the correct statement(s).
[γ is the ratio of specific heats Cp (at constant P) and Cv (at constant V)]
