If we decrease the amount of force, and keep all other factors the same, what will happen to the amount of work? the amount of work will go down because the distance will decrease. the amount of work will go up because the distance will decrease. the amount of work will go down because the distance will increase. the amount of work will go up because the distance will increase.

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?

Most short-period comets do not have randomly oriented orbits because

Atank has a shape of a cone with a radius at the top of 2 m and a height of 5 m. the tank also has a 1 m spout at the top of the tank. the tank is filled with water up to a height of 2 m. find the work needed to pump all the water out the top of the spout. (use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.)
