A man roller skates up a hill at 12.5 m/s but slows down, comes to a stop and then accelerates back down the hill until he is going 13.7 m/s the other direction. Assuming the acceleration is constant and this take 18.3 s, what is the man's displacement?

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.

i think its d if wrong im sorry

uio

explanation:

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.
