A fence post was struck by a lightning bolt and was vaporized. It was estimated that the lightning voltage between the overhead cloud and the post was 1,200,000 volts. Although the lightning bolt only lasted 0.03 seconds it moved 24 Coulombs of charge. (a) How many elecrons were carried in the lightning bolt and how much current flowed in the post from the lightning strike? (b) How much power was produced and how much energy was in the lightning strike? (c) How long could a 60 watt light bulb stay lit if all of the lightning's energy was used to operate it?

In proton beam therapy, a beam of high-energy protons is used to kill cancerous cells in a tumor. In one system, the beam, which consists of protons with an energy of 2.8×10−11J2.8×10−11J, has a current of 76 nAnA. The protons in the beam mostly come to rest within the tumor. The radiologist has ordered a total dose corresponding to 3.4×10−3J3.4×10−3J of energy to be deposited in the tumor. A)How many protons strike the tumor each second? B)How long should the beam be on in order to deliver the required dose?

The diagram shows a mass spectrometer used for measuring the masses of isotopes. It consists of an ion generator and accelerator, a velocity selector, and an ion separator, all in a vacuum. In one experiment, tin ions, each of which carries a charge +1.6 × 10-19C, are produced in the ion generator and are then accelerated by a p.d. of 20kV. Tin has a number of isotopes, two of which are tin-118 (118Sn) and tin-120 (120Sn). What will be the final speed of an ion of tin-118?
Electroconvulsive therapy is a last-line treatment for certain mental disorders. In this treatment, an electric current is passed directly through the brain, inducing seizures. The total charge that passes through the brain is called the dose. In a typical session, a dose of 0.093 C is applied, using a pulse of current that lasts 1.0 ms. What is the current during this pulse?

A velocity selector is used to isolate ions with a single speed. In the velocity selector, the isolated ions go through undeviated, though being acted upon by forces from both the electric and magnetic fields. Write down the condition and equation which must be satisfied if the ions are to emerge from the exit hole of the velocity selector. Define the terms in the equation. Redraw the section of thevelocity selector and indicate the different forces acting on the ions there and use it…
