A horizontal cylinder is separated into two compartments by an adiabatic, frictionless piston. One side contains 0.2 m3 of nitrogen and the other side contains 0.1 kg of helium, both initially at 20°C and 95 kPa. The sides of the cylinder and the helium end are insulated. Now heat is added to the nitrogen side from a reservoir at 500°C until the pressure of the helium rises to 120 kPa. Analyze the system using the thermodynamics conservation equations, determine
(a) the final temperature of the helium,
(b) the final volume of the nitrogen,
(c) the heat transferred to the nitrogen, and
(d) the entropy generation during this process.
A circular wire loop whose radius is 19.0 cm carries current of 2.30 A. It is placed so that the normal to its plane makes an angle of 29.0° with a uniform magnetic field of 11.0 T. Calculate the magnetic dipole moment of the loop.
A bungee jumper (m = 73.00kg) tied to a 48.00m cord, leaps off a 78.00m tall bridge. He falls to 6.00m above the water before the bungee cord pulls him back up. What size impulse is exerted on the bungee jumper while the cord stretches?
