Calculate the net work of the cycle.One cycle contains two processes for an air piston-cylinder device. The first process is an isothermal process and the second process is a polytropic process (PV1.2=const). Through the first process, 0.15kG of air is expanded from 2Mpa and 350°C to 500kPa and through the second process the air returns to the initial state.
External forces compress 21 mol of ideal monatomic gas; during the process the gas transfers 15 kJ of heat to its surroundings, How much work was done on the gas
In this problem you will determine the distance to Jupiter by applying F=ma for circular orbits. By observing Jupiter we can determine that it takes 11.895 years to orbit the Sun. determine the distance of Jupiter from the Sun
Two capacitors are connected to a battery. The battery voltage is V = 50 V, and the capacitances are C1 = 2.00 ?F, Determine the total energy stored by the two capacitors
