Describe the motion of a ball being thrown straight up in the air in terms of kinetic and potential energy. as the ball rises up and balls back down, how is kinetic and potential energy affected? when is each type of energy the greatest and the least? what is true about the total mechanical energy of the ball?

Amplitude is a measure of a waves a; speed b; distance c; energy d; frequency

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.

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )
