What do the length of the cord and gravity determine for a pendulum? a. velocity b. amplitude c. period d. speed

 C

Period/ Period of the pendulum.

Content:  

Simple pendulum is a small diameter bob which is suspended from light cord or string. The string is strong enough to stretch.

Pendulums are quiet common in use such as clocks, swings etc.,

From the simple pendulum we can find conditions under which it performs simple harmonic motion and we can also derive the expressions for Period of pendulum, frequency etc.

Period of a pendulum/Time period is given by the following expression

              T =2π.√(L/g) seconds

                T = period of pendulum in seconds

                L = Length of the string/cord in meters

                g = gravitational force in m/s²   ( g = 9.8 m/s² )

Period of pendulum is independent on mass of the bob.

So, The relation between length of the cord and gravity is used to determine the period of pendulum

i think if it were me i whould divide 300 dide 15

step-by-step explanation:

i think the answer would be b
