5. You push a 0.4 kg sandwich with your hand across a table to your friend over a distance of 0.75 m. If you use 2.4 N of force how much work did
you do? (one of the numbers is not needed for this problem)

an obstruction

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.
