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 = _____ %.
Solar cells generate a potential difference when exposed to sunlight. In an experiment, you wish to charge a rechargeable battery by connecting it in series to an array of solar cells. You perform the experiment outdoors, in direct sunlight, when the intensity of solar radiation is 1000 W/m2. However, your solar cells only have an efficiency of 11% (that is, only 11% of the sunlight power transmitted to the solar cells is delivered to the rechargeable battery). While the circuit is connected, you measure at one instant the potential difference across the battery to be 4.90 V and the current in the circuit to be 0.25 A. What is the area of the array of solar cells?

You are studying temperature dynamics in a desert ecosystem in southeastern Arizona using a new technology that you have invented to track the movement of heat originating from a single source. You begin your study by measuring the electromagnetic energy being emitted from a lizard's skin, which you find is rapidly transported away by a breeze that replaces the warm air around the lizard with cooler air. The heat energy is transported by the wind up the face of a small mountain, where the air is cooler. On the mountain, the heat energy comes into contact with a mouse's skin, and the energy is transferred to the mouse. As more and more energy is transferred to the mouse, it begins to pant and sweat to cool itself down. Describe in order the modes of heat gain and loss that you have observed in your study.
