Answer:
Since you would have to do work on the charge to bring it back to its original position, the charge moves to a position of lower potential and lower potential energy.
The correct answer is
<span>c the friction force from the road
In fact, the friction force between the road and the tires of the car acts as centripetal force, keeping the car in circular motion.</span>
<span>A physical change involves a change in physical properties. Examples of physical properties include melting, transition to a gas, change ofstrength, change of durability, changes to crystal form, textural change, shape, size, color, volume and density.b
A) physical properties</span>
Answer:
1. Simply τ = m x g x r = 54kg x 9.8m/s² x 0.050m = 26 N·m
2. The bucket creates a torque
τ = 75kg x 9.8m/s² x 0.075m = 55 N·m,
so we must create the same torque with the handle.
55 N·m = F x 0.25m
F = 220 N
