An object that moves in uniform circular motion has a centripetal acceleration of 13 m/s^2 . If the radius of the motion is 0.02m, what is the frequency of motion?

f = 3.97 Hz

Explanation:

Given that,

Centripetal acceleration,

The radius of motion is 0.02 m

The formula for the centripetal acceleration is given by :

The speed of an object in a circular path is given by :

t is time period

Also, f=1/t (f is frequency)

Hence, the frequency of motion s 3.97 Hz.

there are no components of a physical goal mentioned on the list of choices that you've provided.

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.
