Because the object hovering over the magnet is the same magnetic pole.
Answer:
So do 2400 divided by 70. I got 34.285714 and the numbers behind the decimal are repeating. If you round it you get 34.3
Answer:
0.5I0
Explanation:
Because once ligh passes though any polarizer 50% of it is gone. The second polarizer is also oriented in the same direction so it passes through with no effect.
Beats only occur when the frequency of two objects is interfere with one another and when those objects are made to identical amplitudes together.
Explanation:
A basic law of magnetism is that unlike poles attract each other. Two bar magnets can illustrate this. ... A pole of the second is brought, in turn, near each of the two ends of the hanging magnet.
Second Law of Magnetism
The force is in direct proportion to the product of the forces of the pole. The force exists in inverse proportion to the square of the middle distance between the poles. The force is dependent on the specific medium in which the magnets are placed.
