A truck has a velocity of 25 m/s and a momentum of 25.000 kg*m/s. What is its
mass?

1000kg

Explanation:

We can use the equation "p=mv"

If we rearrange the equation to find mass (m), then the equation becomes:

m=p/v

We can substitute in the values of p and v as they are already given in the question.

So, now we just substitute in the values to get our answer.

m=p/v

m=25,000/25

m=1000kg

c) up is the direction the magnetic force is acting on the charge.

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
