A person wants to use a lever to lift a dumpster weighing 4200 N. The lever is arranged so that it is approximately horizontal and makes contact below the dumpster's center of mass at a distance of 0.40 m from the lever's pivot. About how much torque will the dumpster exert on the lever?

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
