Abeam of z-polarized atoms with angular momentum quantum numbers 1 「and m- 0 passes between the poles of two stern-gerlach magnets one after the other. the first magnet is oriented in the r direction and the second in the z direction. all beams emerging from the first magnet pass between the poles of the second. (a) how many beams emerge from the second magnet? explain. (b) what are the polarizations (angular momentum quantum numbers) of those beams and what fraction of the incoming atoms emerge in each beam?

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
