Suppose 1.0 mol of a monatomic ideal gas initially at 10 L and 330 K is heated at constant volume to 660 K, allowed to expand isothermally to its initial pressure, and finally compressed at constant pressure to its original volume, pressure, and temperature.
(a) What is the net energy entering the system (the gas) as heat during the cycle?
(b) What is the net work done by the gas during the cycle?
(c) What is the efficiency of the cycle?
A 20.0 kg wood ball hangs from a 1.3 m long wire. The maximum tension the wire can withstand without breaking is 300 N. A 0.70 kg projectile travelling horizontally hits and embeds itself in the wood ball.
Figure (a) below gives the magnitude E(x) of the electric fields that have been set up by a battery along aresistive rod of length L = 9.02 mm (Fig. belowb). The vertical scale is set by Es =4.02 ×103 V/m.
