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?
A proton (mass = 1.67 x 10 -26 kg charge = 1.60 x 10 -19 C) is running at a speed of 8.50 x 10 4 m/s at a point in an evacuated region of space where the electric potential is 3
