A train, weighing 80 tons, is running at a speed of 44 feet per second when the steam is cut off and a constant retarding force applied by the brakes. Find the average time-rate of change of momentum exerted by the brakes if the train is brought to rest in traversing a distance of 300 yards. 2. State the laws of Boyle and Charles for gases, and describe the experiments by means of which you could verify one of them. One litre of dry air at 0° C. and pressure 760 mms. of mercury weighs 1'293 grammes. Calculate the weight of a litre of air at 100° C. and under a pressure ot 800 mms. of mercury. 3. Define (1) specific heat of a substance, (2) latent heat of a substance. A vessel contains 3 lbs. of ice and 7 lbs. of ice-cold water. Steam at 100° C. is condensed in a worm in this vessel, and issues from the worm as water. Find what quantity of steam must be condensed in order to melt the ice and raise the temperature of the contents of the vessel 16 C. [Latent heat of water = 80; latent heat of steam = 53<.] [over.
