the answer is a molecular contact I am pretty sure
Answer:
here it is
Explanation:
Sodium Potassium Aluminum Calcium Lithium Mercury Arsenic Indium Magnesium Copper Iron Lead Germanium Beryllium Francium Polonium Radium Barium Strontium Tin
the answer is A. Their is less friction between the tire and the road at position A than at position B.
Vb - Va = -366.7 V.
Vab = Va - Vb, the potential of a with respect to b, is equal to the work done by the electric force when a unit of charge moves from a to b, it is given by:
Vab = Va - Vb = Wab/q,
So, in order to determinate the potential difference Vb - Va we have to multiply by -1 both side of the equation above:
- (Va - Vb) = - (Wab/q)
Resulting
Vb - Va = -(Wab/q)
Given a positive charge q = 6.0μC = 6.0x10⁻⁶C, Wab = 2.2x10⁻³J. Determine Vb - Va.
Vb - Va = - (2.2x10⁻³J/6.0x10⁻⁶C)
Vb - Va = -366.7 J/C = -366.7 V
