What process does a lens use to deflect light rays from passing through it.

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

Why does it dangerous to jump from a moving vehicle?

Humid air is a better electrical conductor than dry air. explain why you are most likely to receive a shock after walking across a carpet when the air is dry than when the air is humid.
