g = 9.8 m / s2.
l = 10 m.
The period T of a string or mathematical pendulum is determined by the formula: T = 2 * P * √l / √g, where P is the number pi, l is the length of the pendulum, g is the acceleration of gravity.
T = 2 * 3.14 * √10 m / √9.8 m / s2 = 6.3 s.
The oscillation frequency v is the reciprocal of the period T: v = 1 / T.
v = 1 / 6.3 s = 0.16 Hz.
Answer: T = 6.3 s, v = 0.16 Hz.
