1. Two strings, each 13.7m long, are stretched side-by-side. One string has a mass of 78.0 g and a tension of 259.0 N. The second string has a mass of 58.0 g and a tension of 203.0 N. A pulse is generated at one end of each string simultaneously.

What is the speed of the wave on the first string?

____________m/s

2.What is the wavelength of a wave whose speed and period are 65.0 m/s and 5.00 ms, respectively?

_____________m

3. A transverse wave on a string is described by y(x, t) = A cos (t + kx), where A = 0.400 mm, = 34.8 rad/s, and k = 5.80 rad/m.

In what direction does the wave travel?

a. +x-direction

b. +y-direction

c. y-direction

d. x-direction
