Which of the following is an electric potential?
A. 2.5C
B. 2.5 J
C. 2.5 N
D. 2.5 V

D. 2.5 V

Explanation:

Electric potential of a point in space is a scalar magnitude that allows a measurement of the electric field at that point to be obtained through the electrostatic potential energy that a electric charge would acquire if it is placed at that point.

Hope this helps a lot!!

conservation of mass

mass before something happens = mass afterwards

a. spokes of a wheel.

as indicated in the question radial contains rad, also found in radius, so the fracture's would span the radius.
