Answer:
L = 0.635m
Explanation:
This problem involves the concept of stationary waves in pipes. For pipes closed at one end,
The frequency f = nv/4L for n = 1,3,5....n
For pipes open at both ends
f = nv/2L for n = 1,2,3,4...n
Assuming the pipe is closed at one end and that velocity of sound is 343m/s in air. If we are right we will obtain a whole number for n.

Answer:
The charge passes a given point in the conductor during this time is 9.8 C.
Explanation:
Given that,
Current = 1.4 A
Time = 7.0 sec
We need to calculate the charge during this time
Charge :
Charge is the product of current and time.
In mathematically form,
Where, i = cirrent
t = time
Put the value into the formula
Hence, The charge passes a given point in the conductor during this time is 9.8 C.
