1. A string vibrates at its natural frequency of 300 Hz. (a) Calculate the new natural frequency when the tension is increased by 5% without
altering the length.
(b) A second string has the same tension as the original string but twice the mass
per unit length. Calculate the natural frequency of the second string.​
