i have no idea how to calculate this... at all.. T_T

wave speed (v) = w/k y= Asin(kx-wt) w = 125.7 k=2.5 v = 125.7/2.5 = 50.38 m/s (wave speed)But i do not know how to calculate the tension! HELP PLEASEE!

for number 1, y =Asin(kx-wt) k = 2∏/λ k = 26 so λ = 2∏/26 = wavelength = 0.242 m. But I'm having problems with 2 and 3.

I don't even know how to solve the question! what equations do I need?

1.) What is the entropy change of a 33.0 g ice cube that melts completely in a bucket of water whose temperature is just above the freezing point of water? (J/deg) 2.) What is the entropy change of a 7.3 g spoonful of water that evaporates completely on a hot plate whose temperature is...

A 11 g ice cube at -20°C is placed in a lake whose temperature is 13°C. Calculate the change in entropy of the cube-lake system as the ice-cube comes into thermal equilibrium with the lake. The specific heat of ice is 2220 J/kg*K. (Hint: Will the ice cube affect the temperature of the lake?)...

Two sinusoidal waves, identical except for phase, travel in the same direction along a string and interfere to produce a resultant wave given by y(x,t)=(2.5 mm)sin(26.0x -4.0 s-1 * t+0.400 rad), with x in meters and t in seconds. 1.) What is the wavelength of the two waves (m)? [I...

The linear density of a string is 5.520×10-3 kg/m. A transverse wave on the string is described by the equation y=(0.033 m)sin(2.50 m-1x +125.7 s-1 * t). 1.) What is the wave speed? 2.) What is the tension in the string? I've already calculated the wave speed but I don't...
