How does the setup shown in the picture affect
the mechanical advantage required to lift the
clay block?
the setup decreases the amount of
force required to lift the block and,
therefore, increases the mechanical
advantage.
the setup increases the amount of

mechanical advantage
the setup does not change the
amount of force required to lift the
block.

where’s the list ? the question is incomplete

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.

the moving of the box is a result of centripetal force. think of that  as a car or a truck in this case creates a turn, the force of friction performing upon the turned wheels of the car runs centripetal force obligatory for circular motion for the things inside it.
