A train travels up a hill that is 100 meters long. If the train has climbed 50 meters vertically. How far the train traveled horizontally

27.3 meters

Explanation:

A train travels up a hill that is 100 meters long. If the train has climbed 50 meters vertically, it traveled 27.3 meters vertically. Therefore, the answer is 27.3 meters.

(100)² = (50)²+x²

10000 - 2500 = x²

7500 = x²

x = 27.3 or 27.3 meters

e/c, where e is its total energy

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
