An astronaut wishes to visit the Andromeda galaxy, making a one-way trip that will take 30.0 years in the spaceship’s frame of reference. Assume the galaxy is 2.00 million light-years away and his speed is constant. How fast must he travel relative to Earth?

a sonic boom is a loud boom that breaks the sound barrier

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.
