An air bubble has a volume of 1.1 cm3 when it is released by a submarine 110 m below the surface of a freshwater lake. what is the volume of the bubble (in cm3) when it reaches the surface? assume that the temperature and the number of air molecules in the bubble remain constant during the ascent. (the density of water is 1,000 kg/m3.)

Air is to be preheated by hot exhaust gases in a cross-flow heat exchanger before it enters the furnace. air enters the heat exchanger at 95 kpa and 20°c at a rate of 0.6 m^3/s. the combustion gases (cp = 1.10 kj/kg°c) enter at 160°c at a rate of 0.95 kg/s and leave at 95°c. determine the rate of heat transfer to the air and its outlet temperature.

What property of an object determines its inertia?

Asailboat is traveling to the right when a gust of wind causes the boat to accelerate leftward at 2.5m/s2 for 4s. after the wind stops, the sailboat is traveling to the left with a velocity of 3.0m/s.assuming the acceleration from the wind is constant, what was the initial velocity of the sailboat before the gust of wind? answer using a coordinate system where rightward is positive.
