The image attached is a neat copy of a photo of an electricity meter for a domestic solar array. The display shows the energy we sold to the electricity company on a winter's day. Each box is 100 W high and 1 hr wide. At the radius of the earth's orbit, the intensity of sunlight is I=1.4 kW.m–2 . (This means that 1.4 kW.m–2 passes through 1 square metre at right angles to the sun's rays.) The solar array in the previous question consists of 10 panels, each with area A=1.6 m2 . Under optimal conditions - with the sun at right angles to the array and no clouds in the sky - the array produces Pout=2.3 kW .
What is the efficiency of the array? Power out/power in = _____ %.

- 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). (a.) In practice, all ions produced by the ion generator have a range of speeds. 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. The plates producing the electric field have a separation of 2.0cm. The potentials of the plates are marked on the diagram.
