Question

#1. Find the speed at which waves will travel on a string with linear mass density of 1 .0010-3 kg/m and a tension of 0.500 N. Give answer to three significant figures. #2. You observe a traveling wave with a frequency of 32 Hz and a wavelength of 1.4m. What is the speed at which this wave is travelling? Give answer in m/s to two significant figures. #3. You hang a total mass of 0.400 kg on the end of a string that is held fixed at its other end. a) What are the SI units of Tension? (b) What is the tension in the string? Give answer in SI unis to two significant figures. #4.What is the frequency of the fundamental mode of a 1.5 m long string with linear mass density of 0.001 kg/m and a tension of 0.5 N. #5. What is the fundamental frequency of a string that has a length of 1 m and a wave speed of 45 m/s?

Explanation / Answer

1] speed v = sqrt(T/u) where T is tension and u is mass density

= sqrt(0.5/1e-3)

= 22.4 m/s answer
