Answer:
Part a)
Part b)
Explanation:
Part a) what is its frequency, in rev/s
we have that
An old-fashioned LP record rotates at 33 1/3 RPM
so
Convert mixed number to an improper fraction
Remember that
Convert rev/min to rev/sec
Simplify
Part b) what is it period, in seconds
we know that
The period is the reciprocal of the frequency
therefore
the frequency is

Answer:
62.7 VA
Explanation:
The apparent power (power supplied by the source) of an AC circuit is determined by
The impedance(Z) depends on the frequency, but in this case it is given to us that it is 102 ohms at this frequency.
So:
