Answer:
Explanation:
Let the frequency ,
Now the unit of frequency is hertz = s⁻¹ = T⁻¹ where T is time, tension T = kgm/s² = MLT⁻¹ and linear density m = kg/m = ML⁻¹.
So,
![T^{-1} = L^{x}[MLT^{-2} ]^{y}[ML^{-1} ]^{z}\\](https://tex.z-dn.net/?f=T%5E%7B-1%7D%20%20%3D%20L%5E%7Bx%7D%5BMLT%5E%7B-2%7D%20%5D%5E%7By%7D%5BML%5E%7B-1%7D%20%5D%5E%7Bz%7D%5C%5C)
collecting the like bases, we have
![T^{-1} = [L^{x + y -z}][M^{y + z} ][T^{-2y} ] \\L^{0} M^{0} T^{-1} = [L^{x + y -z}][M^{y + z} ][T^{-2y} ]](https://tex.z-dn.net/?f=T%5E%7B-1%7D%20%3D%20%5BL%5E%7Bx%20%2B%20y%20-z%7D%5D%5BM%5E%7By%20%2B%20z%7D%20%5D%5BT%5E%7B-2y%7D%20%5D%20%5C%5CL%5E%7B0%7D%20M%5E%7B0%7D%20T%5E%7B-1%7D%20%3D%20%5BL%5E%7Bx%20%2B%20y%20-z%7D%5D%5BM%5E%7By%20%2B%20z%7D%20%5D%5BT%5E%7B-2y%7D%20%5D)
Equating powers on both sides, we have
x + y - z = 0 (1)
y + z = 0 (2)
-2y = -1 (3)
From (3), y = 1/2
From (2), z = -y = -1/2
Substituting y and z into (1), we have
x + y - z = 0
x + 1/2 - (-1/2) = 0
x + 1/2 + 1/2 = 0
x + 1 = 0
x = -1
So,
