Shoulder pain is any pain in or around the shoulder joint. When tendons become trapped under the acromion, the rigid bony arch of the shoulder blade, it can cause shoulder pain called impingement syndrome.
The period for a simple pendulum does not depend on the mass or the initial anglular displacement, but depends only on the length L of the string and the value of the gravitational field strength g, according to The mpeg movie at left (39.5 kB) shows two pendula, with different lengths.
Lesson 44: Frequency, Wavelength, & Amplitude. The period means that it will take 4.5 seconds for the pendulum to swing back and forth once. So, I expect that my frequency will be a decimal, since it will complete a fraction of a swing per second. Be careful when changing the 700nm into metres.ince frequency and period are exact inverses of each other, there is a very basic pair of formulas you can use to calculate one if you know the otherâ¦. It is very easy to do these calculations on calculators using the x -1 button. Example 1: The period of a pendulum is 4.5s.
