The magnetic field going through a stationary circular loop increases from zero to 5 T in a certain time t. The induced current in the loop will depend on the radius of the loop, r, the resistance of the loop, R, and the time, t. If two of these stay constant, the induced current can be directly proportional to:
a. r.
c. R.
b. t.
d. none of these

Question 2

The wavelength of a traveling wave can be calculated if one knows the:
a. frequency.
c. amplitude and frequency.
b. speed and amplitude.
d. frequency and speed.
