Answer:
168.57 mV
Explanation:
Initial magnetic flux = BA , B magnetic field and A is area of loop
= .35 x 3.14 x .37²
= .15 Weber
Final magnetic flux
= - .2 x 3.14 x .37²
= - .086 Weber
change in flux
.15 + .086
= .236 Weber
rate of change of flux
= .236 / 1.4
= .16857 V
= 168.57 mV
Answer:
I think the answer is b but i cannot confirm cuz this is a challenging question
B. I think is the correct answer
Answer:
v=wavelength ×f
wavelength=v/f=455/655=0.694m
