Some trains use a system known as maglev instead of wheels. In one version of maglev, magnets inside the track act on magnets inside the train, and when the train is at full speed it never touches the ground. The magnets never touch, but the force between them can be changed by adjusting the amount of current flowing through the train's control system. What force do these maglev trains reduce by using magnets?

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.

Alead ball is dropped into a lake from a diving board 5m above the water . it hits the water with a certain velocity and then sink with constant velocity in bottom . it reaches the bottom 5 second after it is dropped if g= 10m/s2 . find depth of the lake and average velocity of the ball ?
