PLEASE HELP I ONLY HAVE 12 MINUTES!! The pendulum of the grandfather clock shown below swings at a maximum angle of 25 degrees.
Vaselesa [24]

Answer: T = 2π√(I/mgD)

Step-by-step explanation:

where:

m is the mass of the pendulum;

I is the moment of inertia of the mass; and

D is the distance from the center of mass to the point of suspension.

Determine the length of the pendulum. For example, it can be equal to 2 m.

Decide a value for the acceleration of gravity. We will use the Earthly figure of 9.80665 m/s², but feel free to check how the pendulum would behave on other planets.

Calculate the period of oscillations according to the formula above: T = 2π√(L/g) = 2π * √(2/9.80665) = 2.837 s.

Find the frequency as the reciprocal of the period: f = 1/T = 0.352 Hz.

You can also let this simple pendulum calculator perform all calculations for you!

WHAT IS THE ANSWER??? HELP
antoniya [11.8K]

Answer:

C

Step-by-step explanation:

The graph has a  x - axis of amount of scarves in intervals of 1 and a y - axis of hours in intervals of 20

Using this information we can see that in the ordered pair, 1 represents x and 16 represents y, which means that the scarves ar 1 and the hours are 16 in the ordered pair

C makes the most logical sense because there is nothing about centimeters in the graph and the scarves are not in the y, but rather in the x
