Solutions to Question 4 please
4. A string of linear mass density of 0.0169 g/cm is attached at one end to a wall. At the other end,
it passes over a massless pulley and is attached to a hanging mass. Determine the tension in the
string and the wave speed if the hanging mass is
a. 200 g
b. 100 g
5. Instead of being attached to a wall, the string is attached to a motor generating sinusoidal wave.
The length of string between the motor and the pulley is 2.5 m. Using the information found in
the previous questions, find the frequencies for the first five modes. Take that opportunity to fill
in the theoretical parts of the lab report tables.
