You are designing an ac generator with a maximum emf of 8.0 V. If the generator coil has 200 turns, each with a cross-sectional area of 0.030 m2,
what should be the frequency of the generator in a magnetic field of 0.030 T?
A) 7.5 Hz B) 7.1 Hz C) 44 Hz D) 8.0 Hz
Question 2
A wheel starts from rest and has a uniform angular acceleration of 4.0 rad/s2. After the wheel completes its first revolution, how long does it take for it to make its second complete revolution?
What will be an ideal response?
