The bolts on a car wheel require tightening to a torque of 1 N∙m. If a 4 cm long wrench is used, what is the magnitude of the force required when the force is applied at 3° to the wrench? Round your answer to the nearest Newton.

Which would not reduce the amount of green house gasses in the air

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.
