Kinetic energy and velocity are at zero when the magnets are held apart, and both increase rapidly when they are released and move together. Energy stored in the magnetic field decreases.
Answer:
Explanation:
Wave’ is a common term for a number of different ways in which energy is transferred:
In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields.
In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels.
In water waves, energy is transferred through the vibration of the water particles
<span>If a plane has a velocity of 300 km/h and a tailwind of 20 km/h, then the vectors of both forces would add (assuming that the tailwind is blowing exactly at the airplanes back) to a total of 320 km/h. Hope it helps

Answer:
The smallest distance the student that the student could be possibly be from the starting point is 6.5 meters.
Explanation:
For 2 quantities A and B represented as
and 
The sum is represented as
For the the values given to us the sum is calculated as

Now the since the uncertainity inthe sum is 
The closest possible distance at which the student can be is obtained by taking the negative sign in the uncertainity
Thus closest distance equals
meters
