Yates says Atlanta has come a long way since the '70s. But Silicon Valley has several key advantages: easy access to capital and a network of seasoned entrepreneurs. And, Yates says: Maybe this is a cultural difference in the rest of the world versus the Valley, but it's the idea that in the Valley, it's OK to fail.
The angular frequency is measured in radians per second. The inverse of the period is the frequency f = 1/T. The frequency f = 1/T = Ï/2Ï of the motion gives the number of complete oscillations per unit time. It is measured in units of Hertz, (1 Hz = 1/s).
Calculate the time of one oscillation or the period (T) by dividing the total time by the number of oscillations you counted. Use your calculated (T) along with the exact length of the pendulum (L) in the above formula to find g.. This is your measured value for  g. . Repeat the above procedure for 3 more cases. Choose 3 other values for L between 125cm and 158cm and record them in the Table in rows 2, 3, and 4.
