31. Find a resultant wave for the two waves shown in Figure P11.31 at the instant they are traveling through the same medium. FIGURE P11.31 AP (N/m²) AP (N/m²) 0.002 f=200 Hz 0.001 А

A  progressive wave travelling in the x-direction is represented by the following equation: ?=?sin(??−??)y=Asin⁡(Bt−Cx).   Given that parameters ?A, ?B and ?C are given in SI units calculate the velocity of the wave for ?=50A=50 , ?=B= 2058 and ?=C= 30.

The density of aluminum is 2700 kg/m3. If transverse waves propagate at 34 in a 4 mm diameter  aluminum wire, what is the tension on the wire in Newtons? Give your numerical answer as a whole number please.

2π.χ. λι -₁), 1. In the geometry of the following figure, the wave in region 1 is given by y₁(x)=C₁sin (5 where ₁ = 4.97 cm, and ₁ = -65.3°. In region 2, the wavelength is ₂ = 10.5 cm. The boundary A is located at x = 0, and the boundary B is located at x = L, where L = 20.0 cm. Find the wave functions in regions 2 and 3.
