Answer:
Explanation:
Using the Gauss Law, we obtain the electric Field for a uniform large line of charge:
We calculate the potential difference from the electric field:
B. As job efficiency increases, stress levels decline (THIS IS WRONG)I think its between A. As job efficiency decreases, stress levels increaseD. As stress levels increase, job efficiency increases
battery
Explanation:
Electromagnets can be created by wrapping a wire around an iron nail and running current through the wire. The electric field in the wire coil creates a magnetic field around the nail. In some cases, the nail will remain magnetised even when removed from within the wire coil
Answer:
Centripetal force
Explanation:
The force that keeps a bottle moving round and round in circular motion is centripetal force.
Centripetal force is an inward directed force that keeps a body in circular motion. This force keeps a body moving along a circular path.
To find the force, we use the expression below;
F =
F is the centripetal force
m is the mass of the body
v is the velocity
r is the radius
