If the wavelength of wave B is 0.45 m and its frequency is 12 Hz, what is the wave speed?

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.

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.
