Answer:
Incomplete question but the closest ans is
A) The displacement is not zero
Explanation:
For work to be done, the direction of force has to be parallel to or in the same direction as the displacement, this can then be calculated by
θ
Where θ is the angle between direction of force and direction of displacement
By this equation,
if Force is zero, W is zero
if displacement is zero, W is zero
if force and displacement are perpendicular θ=90, cosθ = 0
So A is the cloest choices
Answer: 0.75 W
Explanation:
Given
Current flowing
The first flashlight has a single 1.5 V battery
The second flashlight has three 1.5 V batteries connected to provide 4.5 V
Power is the product of voltage and current.
For the first flashlight
Thus, the first flashlight providing 0.75 W of power.
