Imagine you put a cannon on the top of a very tall mountain. you start firing cannonballs horizontally and each time you add more gunpowder to the cannon (which makes the next cannonball travel further before hitting the ground). is it possible that at some point the cannonball will miss the ground? what does this have to do with the orbit of the moon?

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?
