Answer:
The beat frequency is 6.378 Hz.
Explanation:
Given that,
Length of wire = 10000 m
Weight = 81.34 N
Distance = 0.660 m
Tension = 52 N
Frequency = 196 Hz
We need to calculate the mass of the wire
Using formula of weight


Put the value into the formula


The mass per unit length of the wire

Put the value into the formula


We need to calculate the frequency in the wire
Using formula of frequency

Put the value into the formula


We need to calculate the beat frequency
Using formula of beat frequency

Put the value into the formula


Hence, The beat frequency is 6.378 Hz.
The correct answer is 99.06 .
Since we know that,
1 ft = 12 inches, (1ft)3 = (12)3inches3
& 1 inch = 2.54 cm , (1 inch)3 = (2.54)3cm3
& 1 cm3 = 1ml,
&(1 ml)/1000 = 1L, so (1cm3)/1000 = 1L.
& 1 min. = 60 sec.
Now, 1ft3 = (12)3x(2.54)3/(1000) L
and 1 min = 60 sec
So, 1ft3/min = (12)^3x(2.54)^3/(1000)x(60) L/s
Hence 210 ft3/min = 210x(12^)3x(2.54)^3/(1000)x(60).
= 99.06.
