1. What direction is centrifugal force to the force that holds the object in a round path of motion? to the right
Directly opposite
At a right angle
to the left

i think the answer is a, hope this is right, that would be my best guess.

the doppler effect is used by weather forecasters to measure 

moving clouds

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.
