The nuclei of carbon atoms that are found in nature come in two main “varieties” called isotopes (more on this in chapter 11). the carbon-14 nuclei have a greater mass than the carbon-12 nuclei. the two types of atoms can be separated from each other by ionizing them, accelerating them all to some uniform velocity, and then passing them between the poles of a magnet. why does this separate the two isotopes? describe the motion of the two ion types after passing out of the magnetic field. what would happen if all the atoms did not have the same speed?

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
