Answer:
The funda mental frequency of the original tube is 182Hz.
Explanation:
See the attachment for the calculation steps.
In order to calculate the fundamental frequency of the original closed tube we need to find the length of the tube which is equal to the sum of the lengths of the two new tubes.
For closed tubes
f = nv/4L (n = 1, 3, 5,...n)
f = nv/2L (n = 1, 2, 3,...n)
The details of calculation can be found below in the attachment.
Answer: 0.625N
Explanation:
Given the following:
Magnetic field Force = 0.25N
Length of wire = 8cm
Current = 3.0 ampere
The force that the same field will exert on another wire 20cm long carrying the same current will be :
Since current 'I' is the same ;
0.25 Force = 8cm
x force = 20cm
Cross multiply:
8x = (20 × 0.25)
x = (20 × 0.25) / 8
x = 5 / 8
x = 0.625
Force = 0.625N
