Q.How much heat does it take to increase the temperature of 3.80 moles of a diatomic ideal gas by an amount 30.0K if the gas is held at constant volume? The gas molecules can translate and rotate but not vibrate.

Q. Old MacDonald had a farm, and on that farm he had a gate (see below). The gate is 3m wide and 1.8m high, with hinges attached to the top and bottom. The guy wire makes an angle of 300 with the top of the gate and is tightened by a turn buckle to a tension of 200 N. The mass of the gate is 40kg.
