A. If you want to measure the density of a cube. you measured mass is 10kg\pm ± 0.1kg. All of your length,height and width are 10m\pm ± 0.1m. Using error propagation theory, please calculate the uncertainty...

The wave y1 = 0.12 sin π/3(5x+200t-1) propagates on a string of linear density 0.02 kg/m. (a) Calculate the average power transmitted. (b) If the wave y2 = 0.12 sin π /3(5x+200t+3)...
