With one question!

the average kinetic energy of 1 mole of a gas at -32 degrees celsius is:

3.01 x 103 j

3.99 x 102 j

-3.99 x 102 j

3.80 x 103 j

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
