The answer is the third one. Maglev is short for Magnetic Levitation in which trains skim on a guideway utilizing the guideline of attractive shock. Every magnet has two shafts. Presently in the event that you play with two magnets, you'll understand that inverse shafts pull in, though comparable posts repulse. This shocking property of magnets is utilized as a part of Maglev trains. However,instead of utilizing lasting magnets, the standard of electromagnetism is utilized to make solid and huge impermanent magnets. At the point when an electric current is gone through a loop of wire, attractive field is created around the curl as indicated by Faraday's laws.
Newton's law states that objects at rest/motion will remain at rest/motion "UNLESS" a force is acted upon it.
So the soccer ball got kicked, and then came to rest. This doesn't state that the soccer ball was still rolling when the force of someone's foot kicked the ball.
Answer:
Amplitude 4
When the two waves collide, because they are both crests there is constructive interference. This mean that at the point of collision the amplitude increases.
You add both the amplitudes
1+3=4
