Find Cp for any substance in terms of V, T, P and S.
Hint: How is Cp related to (∂s/∂T)p ?
POSITIVE ACCELERATION: If velocity of a body is enhancing, then its acceleration is said to be positive. The direction of positive acceleration is similar as that of velocity.
A 415V 3-phase a.c. motor has a power output of 12.75kW and operates at a power factor of 0.77 lagging and with an ef?ciency of 85%. If the motor is delta-connected, verify
The scattering of a photon by an electron is known as Compton Effect. The momentum and energy is preserved. Scattered photon will have less power as compare to incident photon (les
Advantages of A.C. transmission of power 1. The power can be produced at high voltages. 2. The maintenance of a.c. sub-stations is simple and cheaper. 3. The a.c. voltage
Explain the principle of particle detection. Draw log n -V graph showing different regions and discuss the significant physical processes taking place in these regions.
