Answer:
4.5m
Explanation:
Distance is the total length of path traveled or covered by a body.
So distance is a scalar quantity, it only has magnitude but no direction.
Therefore:
Total distance = 3 m + (3)
So;
3 + 1.5 = 4.5m
Total distance covered 4.5m by the body.
Answer:
The answer is V =delta U over q
Explanation:
Electric potential is defined as the magnitude of the electric field through the potential energy that a charge would have if placed at that point. Mathematically, the potential is defined with the following expression:
where:
V is the electric potential. Its unit is Julius by Coulomb (J/C).
Ep is the electric potential energy that has a charge
q is the charge
In the question Ep = ΔU
