Answer:
A capacitor has plates of area 8.25 * 10 ^ - 5 m ^ 2 . To create a capacitance of 3.35*10^ -10 F , how far apart should the plates be ?
Explanation:
Photovoltaic cells are the most efficient means of converting solar energy to electricity. Option b is correct.
<h3>What is a cell?</h3>
A cell is a voltage and current-producing device that consists of a single anode and cathode separated by an electrolyte.
One or more cells can make up a battery. One cell, for example, is one AA battery.
Light intensity on a solar cell is often measured in "suns," with one sun roughly equivalent to 1 kW/m².
Concentrated sunlight improves the ratio of current generated while the device is lighted vs when it is dark, hence enhancing output voltage and efficiency.
Photovoltaic cells are the most efficient means of converting solar energy to electricity.
Hence, option b is correct.

Multiply by the fraction (1 kg/1000 gm).
Answer: 80N (choice #4)
Explanation: The force of gravity is proportional to the inverse of the square of the distance. That means, if the distance is cut in half, the square of that is 1/4, and the inverse of that is a factor 4. So the force increases by a factor of 4. Given that the force is 20N, the new force will be 4*20N=80N.
