Voltage is defined as the force that causes electrons to flow. That is option A.
<h3>What is a voltage?</h3>
A Voltage is defined as an electromotive force and the potential difference in charge between two points in an electrical field.
It is equally known as the force that causes electrons of a current to flow.
Mathematically, it's = V = current × resistance.

Answer:
Explanation:
Work done on the lever ( input energy ) = force applied x input distance
= 24 N x 2m = 48 J
Work done by the lever ( output energy ) = load x output distance
= 72 N x 0.5m = 36 J
efficiency = output energy / input energy
= 36 J / 48 J
= 3 / 4 = .75
In percentage terms efficiency = 75 % .
Answer:
Orbital period of the planet will be 207.06 year
Explanation:
We have given the planet have the semi major axis as 35 au
We have to find the orbital period of the planet
From Keplar's third law there is relation between the orbital period and semi major axis which is t 
So 
So orbital period of the planet will be 207.06 year
