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?
QUESTION 1 A car of mass 800 kg is pulling a trailer of mass 300 kg up the slope of angle ? to the horizontal where sine ? = 1/200. Resistance to motion (apart from gravity) is 1.
Given that dH for the reaction is -92.2 kJ mol-1, which is larger, the total bond dissociation energy of the reactants or the total bond dissociation energy of the products?
"It is explaining that at similar temperature and pressure equivalent volumes of all gases contain similar number of molecules".
in a uniform electric field, the potential is 10v at the origin and 8v at each of the points (1,0,0),(0,1,0) and (0,0,1).Find the potential at the point (1,1,1).
in need of projects on '' PHYSICS OF THE BRAIN''. Thanks
