A stationary block has a charge of +6.0*1^-8C. A 0.80-kg cart with a charge of +4.0*106-8C is initially at rest and separated from the block by 0.4m. The cart is released and moves along a frictionless surface to a distance of 1.0m from the block. Determine as many values of the physical quantities describng the motion of the cart as you can

Which statement is true for light passing into a medium that is more optically dense than the first medium through which it past

Which statement best describes how private industry decides where to spend the money on research and development

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
