Auniform thin rod of length 0.928 0.928 m is hung from a horizontal nail passing through a small hole in the rod located 0.043 0.043 m from the rod's end. when the rod is set swinging about the nail at small amplitude, what is the period of oscillation?

Use the empirical rule. the mean speed of a sample of vehicles along a stretch of highway is 70 miles per hour, with a standard deviation of 4 miles per hour. estimate the percent of vehicles whose speeds are between 66 miles per hour and 74 miles per hour. (assume the data set has a bell-shaped distribution.)
