The wave speed to this question is 400 meters
Answer:
Frequency required will be 2421.127 kHz
Explanation:
We have given inductance 
Current in the inductor 
Voltage v = 13 volt
Inductive reactance of the circuit 

We know that


f = 2421.127 kHz
Answer:
n = 1000 pulses
Explanation:
Given that,
The frequency of a pulse waveform, 
To find,
The number of pulses counted during 100 ms.
Solution,
The frequency of a pulse waveform is equal to the number of pulses per unit time. It is given by :



n = 1000 pulses
So, there are 1000 pulses counted in a pulse waveform.
