A dog walks 12 meters to the east and then 16 meters back to the west. For this motion, what is the distance the dog moved? m (answers should be rounded to the nearest tenth - Example: 0.1, 1.5, or 5.0) What is the magnitude and direction of the displacement? Magnitude: m (round answer to the nearest tenth) Direction (N, S, E, W, NE, NW, SE, SW):

An ideal otto cycle has a compression ratio of 10.5, takes in air at 90 kpa and 40°c, and is repeated 2500 times per minute. using constant specific heats at room temperature, determine the thermal efficiency of this cycle and the rate of heat input if the cycle is to produce 90 kw of power.

The air in an automobile tire with a volume of 2.60 ft3 is at 70°f and 21 psig. determine the amount of air that must be added to raise the pressure to the recommended value of 30 psig. assume the atmospheric pressure to be 14.6 psia and the temperature and the volume to remain constant. the gas constant of air is ru = 53.34ft⋅lbflbm⋅r(1 psia144 lbf/ft2) = 0.3704 psia⋅ft3lbm⋅r the amount of air that must be added to raise the pressure is lbm
