A child is walking eastward along a flat sidewalk. She is pulling a wagon behind her with pulling force applied to the handle. The handle makes an angle of 40° with the horizontal. Rather than drawing a slanted arrow in the free-body diagram for the wagon, which two arrows could be substituted for ? an upward arrow labeled Fsin(40°), and a downward arrow labeled Fsin(40°)

two eastward arrows, one labeled Fsin(40°) and the other labeled Fcos(40°)

an upward arrow labeled Fsin(40°), and an eastward arrow labeled Fcos(40°)

an upward arrow labeled Fcos(40°), and an eastward arrow labeled Fsin40°)

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.
