One point has a voltage of 9 volts and a second point 5 millimeters away has a voltage of 3 volts what is the strength of the electric field between these points?

1,200V/m

Explanation:

I will call the first point A and the second point B, we have:

voltage in A:

Voltage in B:

The distance between the points:

And we calculate the electric field due to the difference of potential as follows:

Substituting known values:

the strength of the electric field between these points 1,200V/m

this is poiselle's equation from fluid mechanic in physics. mech eng

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
