In 1.0s, 5.0x10^23 nitrogen molecules strike an area of8.0cm^2 at a speed of 300m/s. What is the pressure? (mass of one nitrogen molecule = 4.68x10^-26 kg.) I believe I should use 1/2mv ^2 for the solution but the answer I keep getting is nowhere near correct. Can someone help with this?
two bodies of masses 200 g and 300 g are tied to a string which is passed over a pully.if pully has no weight and friction,then find the accerlation of the bodies and tension in th
