A simple pendulum consisting of a small object of mass m attached to a string of length /has a period T. A pendulum with which of the following combinations of object mass and string length will also have period T? Object Mass String Length A т/2 Object Mass String Length 1/4 m Object Mass String Length V2m Object Mass String Length 2m 41 Object Mass String Length 4m 21

can someone please help, thank you !

A pendulum oscillates is started with an amplitude of 00 = 5.0°. Its e(t) graph is shown at the top of the figure below. If the same pendulum is started at an amplitude of 0o = 10.0°, which curve best describes the motion of the pendulum? 15 50505 100 10 -5 50505 10 15 10 -5 ? ܟ ܘ ܟ ܘ ܩ 5 -5 -10 50505100 -5 MVY original oscillation XXXXXX 02 (b) @o w 4 6 time (s) @ (f) 8 (f) 10

A pendulum of length L1 has a period  T1 = 0.9000 s. The length of the pendulum is adjusted to a new value L2 such that  T2 = 1.500 s. What is the ratio L2/L1?

Thirty three of the 141 species of New World monkeys are endangered. A biologist studying one of these endangered species realizes that in some cases she can estimate the mass of an animal by period of oscillation when they hang on a vine. When one of the female adults hangs on a particular vine, she oscillates straight up and down at a period of 2.2 s. After the monkey moves to other areas the biologist finds that the vine has a spring constant of 65N/m a) Estimate the mass of the monkey.

A spring-mass system consists of a mass m = 4.0 kg and spring with spring constant k = 145 N/m. What length of simple pendulum would have the same frequency? O 0.27 m O 1.1 m O 0.36 m O 0.54 m O 1.3 m

A 3.2-kg object is suspended from a spring with k = 74 N/m.  The mass is pulled 0.75 m downward from its equilibrium position and allowed to oscillate.  What is the maximum kinetic energy of the object?
