<span>The correct answer is D): resistors B and C. In fact, the energy per unit charge is equal to the voltage across the resistors. The electrical potential energy is in fact: </span>
<span>, where q is the charge and V is the voltage; by rearranging the equation, we have </span>
<span>, therefore the voltage is the energy per unit charge. In the circuit in the figure, the resistors B and C are connected to the same points of the circuit (they are connected in parallel), therefore they have the same voltage, so they have the same energy per unit charge.</span>
Answer:
The work done will be
Explanation:
The work equation is given by:
Where:
F is the force due to gravity (weight = mg)
x is the length of the ramp (3 m)
Now, the force acting here is the component of weight in the ramp direction, so it will be:
Therefore, the work done will be:
