A wave pulse travels along a stretched string at a speed of 274cm/s.
1. what is the speed of the wave if the tension in the string is doubled? Why?
2.What is the speed of the wave if the mass is quadrupled? Why?
3. What is the speed of the wave if the length of the string is quadrupled? Why?

$$v=\sqrt{T/\mu}$$
T is the tension and mu is the mass per unit length.
