Answer:
the impedance of the circuit is 25.7 ohms.
Explanation:
It is given that,
Voltage, V = 50 volts
Frequency, f = 60 Hz
Resistance, R = 25 ohms
Capacitive resistance,
Inductive resistance,
We need to find the impedance of the circuit. It is given by :
Z = 25.7 ohms
So, the impedance of the circuit is 25.7 ohms. Hence, this is the required solution.
Answers:

b) This part can be solved by a Rule of Three:
If 10 waves ---- 16 s
1 wave -----
Then:
This is the period of the wave
On the other hand, the frequency of the wave has an inverse relation with its period
:
This is the frequency of the wave
c) The speed of a wave is given by the following equation:
Finally:
