Leda drop a ball from three different heights, shown. for each drop, she calculate what the kinetic energy of ball would be when it hits the ground. the table shows her data. lesha says that a ball drop from a height of 3.0 meter would have less than 96 joules of kinetic energy when it hits the ground. is she correct and why

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

In addition to gravity, what is the other predominant force that affects the motion of a pendulum?
