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?
Plane and The Package Suppose a plane moving along with a constant speed at an elevated height above the Earth's surface. Within the course of its flight, the plane drops a pac
LENARD ATOMIC MODEL : Lenard suggested that the atom must have a lot of empty in it. Lenard's model of an atom could not explain about the stability and mass of an atom .
If W is atomic weight and N is the atomic number of an element, then: (1) Number of e -1 = W- N (2) Number of 0 n 1 = W- N (3) Number of 1 H 1 = W-N (4) Number of 0
Mass energy relation - The total energy of a body is the sum of its kinetic energy and rest mass energy. Particle having rest mass zero always move with the velocity of light.
