I think the corect answer would be C. When a police officer receives information that you are speeding in your vehicle, she is using the frequency of the wave to measure the Doppler Effect. As the speed of a vehicle increases, the greater the change of the frequency of the waves would be transmitted to the radar guns which is being used by the police officer. Doppler effect is an effect that is observed in sound and light waves as these waves move away or to the direction of the observer. This is being used in many applications like in astronomy, weather balloons, the radar guns,and for underwater researches.
The charge will most likely leave the electric field near C) Y
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
This is a trick question. Since the planets are in orbit all the time the distance changes, which is because some planets orbit faster than others. I hope this helped at least a little bit.
Answer:
Maybe when you bump into the refrigerator and the magnet falls?
Explanation:
This is an example of you interacting with electromagnetics because you must have bumped into something and made a magnet fall.
I hope it helps?
If it does help can I have a brainliest?
