<span>Ohm's law deals with the relation between
voltage and current in an ideal conductor. It states that: Potential difference
across a conductor is proportional to the current that pass through it. It is
expressed as V=IR. Therefore, the correct answer is option B, the voltage would increase as well.</span>
Answer:
B. There are no forces acting on the ball.
Explanation:
There are no forces acting on the ball.
The load is the weight of the rock that Jonathan lifts:

The effort instead is the force applied in input to the lever in order to lift the rock:

So, the ratio between load and effort for this exercise is

So, the ratio is 10:1.
