To test the hypothesis that students who finish an exam first get better grades, Professor Hardtack kept track of the order in which papers were handed in. The first 25 papers showed a mean score of 77.1 with a standard deviation of 19.6, while the last 24 papers handed in sho...
rope has length of 18.8496 with the oscilator on one end and the mass end hanging
A sinusoidal wave in a rope is described by the wave function y = A sin(k x + ! t) , where A = 0.47 m, k = 1 m−1, ! = 26 Hz, x and y are in meters, and t is in seconds. vibrator 26 Hz ì = 3.8 g/m m 18.8496 m If the tension in the rope is provided by an arrangement...
i have sample homework with solution and different numbers. Mass=5.51kg Ms=0.0754g T=1.39s. g(1.39)^2/4*pi^2=.4796 sqrt(5.51/(.000754/.4796))=59.2 answer on this problem is 586.072 m/s
Im still having difficulty coming up with the correct answer.
sorry not hyperbolic..just plain ole sin and yes "i" is a typo
