What is the charge on an object that has 1.09x10^13 excess electrons?

Explanation:

The electron is the particle that rotates around the nucleus of the atom; it has a negative electric charge equal to :

which is known as fundamental charge.

For an object containing N excess electrons, the total charge of the object is

In this problem, the number of excess electrons in the object is:

Therefore, by plugging it the numbers, we can find the value of Q, the total charge of the object:

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

more than, less

less than, more
