Solve the following question given below:

A steel guitar string is stretched between two fixed supports 88.1 cm apart. When the temperature is 0 Ã‚Â°C, the fundamental frequency of transverse oscillations of the string is 189 Hz.

1- What will be the value of fundamental frequency in Hz if the temperature is raised to 45.1 Ã‚Â°C? Useful Data: mass density of steel is: 8.09 x 10³ kg/m³ Young's modulus of steel is 1.93 x 10¹¹ N/m² Coefficient of thermal expansion of steel is 18.1 x 10^-6 /K.

Show all work, use additional paper if necessary.
