Two strings with linear mass densities `mu_(1)=0.1kg//m` and `mu_(2)=0.3kg//m` are joined seamlesly. They are under tension of `20N`. A travelling wave of triangular shape is moving from lighter to heavier string.

In Fig. 16-13, two strings have been tied together with a knot and then stretched between two rigid supports. The strings have linear densities mu_(1) = 1.4 xx 10^(-4)" kg/m "and mu_(2)=2.8. xx 10^(-4)"kg/m". Their lengths are L_1= 3.0 m and L_2=2.0m, and string 1 is under a tension of 400 N. Simultaneously, on each string a pulse is sent from the rigid support end, toward the knot. Which pulse reaches the knot first. Figure 18-13 Two strings, of lengths L_1 and L_2 , tied together with a knot and stretched between two rigid supports.

Power supplied to a vibrating string: A string with linear mass density mu=5.00xx10^(-2) kg//m is under a tension of 80.0 N. how much power must be supplied to the string to generate sinusoidal waves at a frequancy of 60.0 HZ and an amplitude of 6.00 cm?

Two strings A and B are connected together end to end as shown in the figure. The ratio of mass per unit length (mu_(B))/(mu_(A))=4 . The tension in the string is same. A travelling wave is coming from the string A towards string B. if the fraction of the power of the incident wave that goes in sting B is (n)/(9) the value of n is:

Two blocks with masses m_(1) = 0.2 kg and m_(2) = 0.3 kg hang one under other as shown in figure. Find the tensions in the strings (massless) in the following situations : (g = 10 m//s^(2)) if maximum allowable tension is 10 N. What is maximum possible upward acceleration ?
