Current is the amount of charged passed divided by elapsed time.

I = Q/Δt

I = current, Q = charge, Δt = elapsed time

We also know an electron has a charge of 1.6×10⁻¹⁹C, so let us find the total charge by multiplying this unit of charge by the total number of electrons:

Q = 1.6×10⁻¹⁹(3×10²⁰) = 48C

We also have Δt = 6s, so let's plug these values in to solve for I:

I = 48/6

I = 8A

Advocard [28]

Answer: No.

Explanation:

A scientific theory is an explanation of some aspect of the natural world that can be tested several times, and follows the scientific method. And, when possible, theories are tested with experiments.

Now, a scientific theory must meet some criteria, and one of those is that it must be supported by several (and independent) strands of evidence.

In this case, we have only one, Meatball, and it is not enough, then it can not be a scientific theory.

Grace [21]

Answer:

0.5 m/s²

Explanation:

according to Newton's second law, we are goven a relationship between force, mass and acceleration, with the formula:

F = m×a

F for force

m for mass

a for acceleration

we use the given data and get:

20 = 40×a

we find a=20/40=0.5m/s²
