A 38% efficient power plant puts out 850 MW of electrical power. Cooling towers take away the exhaust heat. (a) If the air temperature is allowed to rise 7.0 Co, estimate what volume of air (km3) is heated per day. Wil the local climate be heated significantly?
(b) If the heated air were to form a layer 180 m thick, estimate how large an area it would cover for 24 h of operation. Assume the air has density 1.3 kgm. and has specific heat of about 1.0 kJ /kg. Co at constant pressure.

Abox is pushed down at an angle of 32 degrees on a rough surface. the box moves to the right. what equation should be used to find the net force in the y-direction? answers: a. fnet, y = fn - fgb. fnet, y= fp - ffc. fnet, y = fn-fg- fpcos(32)d. fnet, y = fn-fg-fpsin(32)

Aplane flies directly between two cities, a and b, which are separated by . from a to b, the plane flies into a headwind. on the return trip from b to a, the wind velocity is unchanged. the trip from b to a takes less than the trip from a to b. what is the airspeed of the plane, assuming it is the same in both directions
