You strike a tuning fork and find that the first harmonic/fundamental resonance is produced when the air column length or height or depth
at 0.166 m. If the speed of sound is 340 m/s, what is the frequency of sound wave produced by the tuning fork in Hz?

answer; (arch); good luck

the awnser is d you right bro                      

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.
