What is an amplitude??

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

Look at the electroscope, describe how you can cause the two leaves at the bottom to repel each other and stay that way

He acceleration due to gravity on the surface of mars is about one third the acceleration due to gravity on earth’s surface. the weight of a space probe on the surface of mars is about
