An amount of ideal gas is con?ned to a sealed box at one-half atmospheric pressure, i.e., 50.65 kPa. With clever control, the volume of the box is reduced to 1/8 of its original value (without any gas leaking in or out), while the temperture is ke..
A vehicle is speeding at 115 km/h on a straight highway when a police car moving at 145 km/h enters the highway from an onramp and starts chasing it.
A moving particle encounters an external electric field that decreases its kinetic energy from 9800 eV to 8350 eV as the particle moves from position A to position B. The electric potential at A is -43.0 V, and that at B is +23.0 V. Determine the ..
