Solar cells generate a potential difference when exposed to sunlight. In an experiment, you wish to charge a rechargeable batteryby connecting it in series to an array of solar cells. You perform the experiment outdoors, in direct sunlight, when the intensity ofsolar radiation is 1000 W/m². However, your solar cells only have an efficiency of 11% (that is, only 11% of the sunlight powertransmitted to the solar cells is delivered to the rechargeable battery). While the circuit is connected, you measure at one instantthe potential difference across the battery to be 5.30 V and the current in the circuit to be 0.27 A. What is the area of the array ofsolar cells?m2

J.J Thomson studied the ionization of atoms in collisions with electrons. He accelerated electrons through a potential difference, shot them into a gas of atoms, then used a mass spectrometer to detect any ions produced in collisions. By using different gases, he found that he could produced singly ionized atoms of all the elements that he tried. When he used higher accelerating voltages, he was able to prodce doubly ionized atoms of all elements except hydrogen. a.why did thomson have to use higher accelerating voltages to detect doubly ionized atoms than to detect singly ionized atoms? b. What conclusion or conclusions about hydrogenatoms can you draw from these observations? Be specific as to how your conlusion are related to the observations.
High-speed flash photography was pioneered by Doc Edgerton in the 1930s, while he was a professor of electrical engineering at MIT. You might have seen examples of his work in the amazing shots of hummingbirds in motion, a drop of milk splattering on a table, or a bullet penetrating an apple . To stop the motion and capture these pictures, one needs a high-intensity, very short pulsed flash, as mentioned earlier in this module. Suppose one wished to capture the picture of a bullet (moving at 5.0×102 m/s ) that was passing through an apple. The duration of the flash is related to the RC time constant, τ . What size capacitor would one need in the RC circuit to succeed, if the resistance of the flash tube was 10.0 Ω ? Assume the apple is a sphere with a diameter of 8.0×10–2 m.

A 0.364 kg toy car is powered by four AA batteries (6.00 V total) connected directly to a small DC motor. The car has an effective energy conversion efficiency of 52.6%, meaning that 52.6% of the electric energy applied to the motor is converted into translational kinetic energy. After 4.96 s, the car, which is initially at rest, reaches a speed of 2.35 m/s. What is the average current supplied to the car's motor? average current: A
