A tugboat is pulling a barge into a harbor. The barge is exerting a force of 3000 N against the tugboat. Which force would most likely allow the tugboat to move the barge into the harbor? –4500 N –2500 N 2500 N 4500 N

the correct one is F’= 4500 N

Explanation:

To solve this problem we must use Newton's second law

where F₁ is the force of the barge F₁ = 3000N and the force of the tugboat is F '

            F '- F₁ = m a

we substitute

            F '- 3000 = m a

the mass is always a positive quantity, therefore if we want the tug to pull the barge

            F ’-3000> 0

when you check it, you respect the correct one is F’= 4500 N

The answer is -4500 N

Explanation:

I just got it right on the test

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
