Silver atoms pass during a Stern-Gerlach magnet with a field gradient of 10 T/cm. If the magnet is 3.5 cm long, and the atoms are moving at 500 m/s, by how far will atoms be deflected? (Mass of atom = 1.79x10^-25, h=1.06x10^-34, me =9.1x10 ^-31, e = -1.602x10^-19, g =2)
A stone is dropped into a river from a bridge 43.90 m above the water. Another stone is thrown vertically down 1.00 after the first is dropped. The stones strike the water at the same time.
