Answer:
n = 756.25 giga electrons
Explanation:
It is given that,
If the charge on the negative plate of the capacitor, ![Q=121\ nC=121\times 10^{-9}\ C](https://tex.z-dn.net/?f=Q%3D121%5C%20nC%3D121%5Ctimes%2010%5E%7B-9%7D%5C%20C)
Let n is the number of excess electrons are on that plate. Using the quantization of charges, the total charge on the negative plate is given by :
![Q=ne](https://tex.z-dn.net/?f=Q%3Dne)
e is the charge on electron
![n=7.5625\times 10^{11}](https://tex.z-dn.net/?f=n%3D7.5625%5Ctimes%2010%5E%7B11%7D)
or
n = 756.25 giga electrons
So, there are 756.25 giga electrons are on the plate. Hence, this is the required solution.

In miles per hour, light speed is about 670,616,629 mph
<span>The correct option is C. Energy cannot be created or destroyed. This statement is known as law of conservation of energy, and it implies that whenever a certain form of energy does change, the loss of this form of energy must have converted into an another type of energy. A typical example is an object falling to the ground: initially, the object has gravitational potential energy. As the object falls down, it loses potential energy (since its altitude from the grounf decreases), but it acquires kinetic energy (because its velocity increases). In this example, potential energy has converted into kinetic energy, but the total energy of the object has remained constant.</span>
