Acharged particle (q = -8.0 mc), which moves in a region where the only force acting on the particle is an electric force, is released from rest at point a. at point b the kinetic energy of the particle is equal to 4.8 j. what is the electric potential difference vb - va?

600 V

Explanation:

 Given

Q=-8 mC

W=4.8 J

And we know

W=QV

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
