How long will it take a transverse pulse to travel on a string of length 100cm and mass 8g under tension of 70?

Velocity may be written as length divided by time, or v = L/t, and the speed of a wave on a string is v = √[F/μ]. Combing these, we have:
L/t = √[F/μ]
Since linear density (μ)is equal to mass divided by length (m/L), we can rewrite it as:
L/t = √[F / (m/L)]
Solving for time, t:
t = √[mL/F]
= √[(0.0080kg)(0.10m) / 70N]
= 0.0034s (3.4ms)
Hope this helps.

In 51 ????? Seconds might make for an extremely small velocity v = a million.7 / 51 = 0.0.33 m/s v = ? T / m/L v^2 = T / m/L m/L = T / v^2 m = a million.7 . 25 . / 0.033 ^2 = 38250 kg it fairly is slightly string with mass 38 tonnes. there is something incorrect with that 51 s
