the magnetic field is strongest near to the poles of the magnet were the lines of flux are more closely spaced.
Answer:
Simple answer: Yes
Explanation:
Even if you touch an item with a stick you re still doing work to it, most of the time something sitting on a table not being disturbed is having work done to it. Everything has the force of gravity working on it to essentially keep the items from floating away so workis being done to it.
Work done can be something so small (e.g) a pencil sitting on a table) or as big as an earthquake or kicking a ball through a window and smashing the glass.
Answer: 11000 N
Explanation:
Given that,
Time required to stop car = 3.0 s
The car's momentum = 33,000
kg m/s
magnitude of force = ?
Recall that impulse is equal to the change in momentum of the car, hence
Impulse (I) = Momentum
(Since I = force x time, then
Force x time = momentum)
F x 3.0 s = 33,000 kg m/s
F = 33,000kg m/s / 3.0s
F = 11,000 N
Thus, 11000N of force was used to stop the car.
