The FBI opens hundreds of civil rights cases each year, and itâs a responsibility the Bureau takes very seriously. The Civil Rights program is comprised of the following subprograms: Hate Crimes, Color of Law, Human Trafficking, and Freedom of Access to Clinic Entrances (FACE) Act.
The equation for the period of a simple pendulum starting at a small angle (a) is: T = 2pi*SQRT(L/g). or. T = 2Ïâ(L/g). where. 1  T is the period in seconds (s). 2  pi = 3.14 (it is also written as the Greek letter Ï).quations for period and frequency. The period of the motion for a pendulum is how long it takes to swing back-and-forth, measured in seconds. Period is designated as T. The frequency of a pendulum is how many back-and-forth swings there are in a second, measured in hertz. Frequency is usually designated as f.
The motion is simple harmonic motion where Î¸ 0 is the semi-amplitude of the oscillation (that is, the maximum angle between the rod of the pendulum and the vertical). The period of the motion, the time for a complete oscillation (outward and return) is. which is known as Christiaan Huygens 's law for the period.). where is the complete elliptic integral of the first kind defined by. For comparison of the approximation to the full solution, consider the period of a pendulum of length 1 m on Earth (g = 9.80665 m/s 2) at initial angle 10 degrees is.
