Answer:
The electric field does positive work on the charge.
The potential energy associated with the charge decreases.
Explanation:
We know that force due to electric filed on a charge particle q given as
F = q E --------1
If the positive charge is moving in the direction of electric filed it means that force due to electric field and displacement of particle due to motion is in the same direction.So the work done due to electric filed will be positive.
Work = Force . Displacement
W= F.d
F= W/d ---------2
From equation 1 and 2
W/d = q E
W/ q = E/ d
We know that voltage difference ΔV
ΔV = E/ d
ΔV =W/ q
So the potential difference will be decrease because charge is positive.So the potential energy will be decreases.
I inferred you've referring to a close electrical circuit.
Answer:
The circuit is complete.
Explanation:
A closed electrical circuit is indeed a complete circuit. Also, it allows charges to flow, the bulbs in the circuit will shine and it is not broken.
It is termed closed circuit because there is no brokage in the series of electrical wires or the switch; which may prevent the free flow of current or charges. Thus, a feature that marks closed circuits is that they are complete.
Answer:
B. 5.9 X 10^9
Explanation:
For this question, we assume the following:
•2.3 x 1014 inches is actually 2.3 x 10^14 inches.
•3.9 x 104inches is actually 3.9 x 10^4inches
We now calculate thus;
The average distance in km would be 2.3 x 10^14/3.9 x 10^4
= 0.59 X 10^10.
Therefore, we have;
5.9 X 10^9km.
There are NO true statements on the list you provided.
