A student is carrying out an experiment with a cobalt-60 source of labelled activity 0.3 MBq. She holds the source in tongs 25 cm long for the duration of the experiment which is 6 minutes. Calculate the maximum dose and the maximum dose equivalent that she could receive. (The relevant exposure rate constant is 0.35 µSv/ MBq h at 1m).

A pair of charged conducting plates produces a uniform field of Eo = 10,859 N/C directed to the right, between the plates. The separation of the plates is L = 37 mm. In Figure, an electron (e = - 1.6 x 10-19 C; m = 9.1 x 10-31 kg) is projected from plate A, directly toward plate B, with an initial velocity of Vo = 2.1×107 m/s. The velocity of the electron (expressed in general form as a whole number) as it strikes plate B is what?
