the linear density of a wire under tension t varies linearly from `mu_(1)` to `mu_(20`.Calculate the time that a pulse would need to pass one to the other.The length of the wire is l

A

`2/3(varphi)/sqrtT((mu_2-mu_1^(3//2))/((mu_2-mu_1)))`

B

`2/3(sqrtT(mu_2-mu_1))/(varphi(mu_2^(3//2)-mu_1^(3//2)))`

C

`2/3(varphi(mu_2-mu_1))/(sqrtT(mu_2^(3//2)-mu_1^(3//2)))`

D
