Calculate the number of electrons passing a point in the wire in 1 min when the current is 12 mA for 25s

see this and answer by your own

Explanation:

How do you calculate the number of electrons passing a point in a wire?

When one coulomb charge passes through any cross section of the wire per second, the current passing is one ampere. Charge of electron ,e=1.6X10^-19C. n=1/(1.6X10^-19)=6.25X10^18. This number of electrons passes through cross section of a wire carrying 1A current.

the answer is a. at the equator

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
