The function of a circuit breaker is to stop a current
that is TOO GREAT, because that's often a sign that
some device in the circuit has failed.
Speed = distance / time = 55 / 0.75 = 73.3 miles per hour.
Work is equal to the force applied to an object multiplied by the distance it had travelled. This is work as long as the force and the direction of the distance in going in the same direction.
It is work because you're applying a force on an object to move it.
For example, work is done when you push a box across the floor, but work is not done when you lift the box up and then walk it across the room. This is because the force on the box is upwards since you're lifting it and the direction of the distance is left or right so the directions are not the same.
Answer:
(-y)-direction.
Explanation:
The force created by the magnetic field on a moving object is
So the directions are
The direction can also be found by the right-hand rule.
Point your index finger in the direction of velocity. Point your middle finger in the direction of magnetic field. Your thumb will point towards the direction of the force.
