If your experiments are not close to each other within experimental uncertainty, perform the experiment again taking steps to improve your design or think of the assumptions you made about the collision – are they valid in this case?

tbh i dont know ether

the diagram which shows forces as either balanced = same speed or unbalanced = accelerarting

increase masses, decrease separation

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.
