Compute the each part of given problem:
Problem: Transverse waves with a speed of 56.0 m/s are to be produced on a stretched string. A 4.25-m length of string with a total mass of 0.0600 kg is used.
Part I: What is the required tension in the string?
N
Part II: Calculate the wave speed in the string if the tension is 8.00 N.
m/s
Please show how you get the answer.
