It doesn't on account of radio waves are longer than optical waves. Radio waves are a sort of electromagnetic radiation with wavelengths in the electromagnetic range longer than infrared light. These long waves are in the radio locale of the electromagnetic range.
Electromagnets can be turned off, this makes it easier to release things from the magnetic field.
Hope this helps :)
From Ohm's law: R = V / I
Resistance = (voltage) / (current)
The first paragraph TELLS you that the current is always 0.5 A, and the table tells you the voltage across each piece of wire.
Again . . . <em>R = V / I</em>
Answer:
The displacement is zero
Explanation:
Displacement is a vector that connects the starting position of motion of an object to the final position. It is a vector quantity, so it has both magnitude and direction.
Viceversa, distance is a scalar quantity that measures the total length of the path covered by the object during its motion.
In this problem, we are interested in the displacement.
We are told that the runner goes around a 1 mile track, and he ends at his starting position: this means that his final position is equal to the starting position, therefore the displacement is zero.
Is that a question what is that supposed to mean
