 # Anna litical and noah formula are experimenting with the effect of mass and net force upon the acceleration of a lab cart. they determine that a net force of f causes a cart with a mass of m to accelerate at 48 cm/s/s. what is the acceleration value of a cart with a mass of 2m when acted upon by a net force of 2f?   ### Another question on Physics Physics, 22.06.2019 10:20
Point charges and are placed at adjacent corners of a square for which the length of each side is 3.00 cm. point a is at the center of the square, and point b is at the empty corner closest to . take the electric potential to be zero at a distance far from both charges. (a) what is the electric potential at point a due to and ? (b) what is the electric potential at point b? (c) a point charge moves from point a to point b. how much work is done on by the electric forces exerted by and ? is this work positive or negative? Physics, 22.06.2019 10:30
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.
