5. What is the difference between speed and acceleration?

“Speed” is the magnitude of the velocity vector. It is part that quantifies the distance traveled per unit time. “Acceleration” is the change in the velocity vector.

Explanation:

Hope this helps!!

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

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.
