The frequency of the middle d note on a piano is 293.66 hz. what is the wavelength of this note in centimeters? the speed of sound in air is 343.06 m/s.

How is the gravitational force related to the distance between two objects?

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.

Energy transformations that involve one transformation from one type of energy to another are called transformations.
