Awire contains a steady current of 2 a. the number of electrons that pass a cross section in2 s is: a. 2b. 4c. 6.3 × 10^18d. 1.3 × 10^19e. 2.5 × 10^19

Number of electrons,

Explanation:

Given that,

Current flowing in wire, I = 2 A

Time, t = 2 s

We need to find the number of electrons that passes through a cross section. The electric current is defined as the electric charge per unit time. It is given by :

Since, q = ne

n is the number of electrons

So, there are passes through a cross section. Hence, this is the required solution.

hi i’m sorry to call us today so we will get back with y’all and we will have to do it haha omg was the day

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
