The difference in electric potential energy between the two points is

where q is the magnitude of the charge and

is the electric potential difference.
But for energy conservation, the difference in electric potential energy

between the two points is equal to the work done to move the charge between A and B:

so we have

and by substituting the numbers of the problem, we find the value of

:
Answer:
a. 12 m/s² down
Explanation:
Acceleration has units of length per time squared. Acceleration is a vector, so it also has a direction.
Answer:
1.Gravity is an invisible force that pulls objects toward each other
2.The suns gravity pulls the planet towards the sun which changes the straight line of direction into a curve
That keeps the planet moving in an orbit around the sun
hope it helped:)
It depends on what that "certain amount" is.
Answer:
1.52 hour
Explanation:
M = 0.5 g, I = 3 A
Electrochemical equivalent of nickel
Z = 3.04 × 10^(-4) g/C
By use of Faraday's laws of electrolysis
M = Z I t
t = M / Z I
t = 0.5 / (3.04 × 10^-4 × 3)
t = 5482.45 second = 1.52 hour
