What is the speed of the wave represented by y(x, t) = A sin(kx t), where k = 6.5 rad/cm and = 6.5 rad/s? _________ cm/s

An overhead electric power line carries a maximum current of 125A. What is the magnitude of the maximum magnetic field at a point 4.50m directly below the power line?

y(x,t) = (1.0 cm) sin [(323 rad/s)t (287 rad/cm)x] From the plots determine the amplitude, wavelength, and speed of the wave. Amplitude = 1.0 cm Wavelength = .022 cm Speed= __________cm/s find the period of the vibration. Period = _______ s so i need to find out speed and period...

Wine bottles are never completely filled: a small volume of air is left in the glass bottle's cylindrically shaped neck (inner diameter d = 18.5mm) to allow for wine's fairly large coefficient of thermal expansion. The distance H between the surface of the liquid contents and the bottom...
