FIND THE LENGTH (IN CM) OF A PENDULUM WITH A PERIOD OF 1.20S.

Yes. 0.357 m or 35.7 cm

To find the length of a pendulum with a period of 1.20 seconds, we can use the formula for the period of a simple pendulum:

T = 2 * π * √(L / g)

Where:
T is the period of the pendulum
L is the length of the pendulum
g is the acceleration due to gravity

Rearranging the formula, we have:

L = (T^2 * g) / (4 * π^2)

Now, we can substitute the given values:

T = 1.20 seconds
g ≈ 9.8 m/s^2 (acceleration due to gravity)

Converting the period to seconds, we have:

L = (1.20^2 * 9.8) / (4 * π^2)

Calculating this expression will give us the length of the pendulum in meters. To convert it to centimeters, we need to multiply by 100:

Length (in cm) = L * 100

Now you can plug in the values and perform the calculation to find the length of the pendulum in centimeters.

For simple pendulum

T =2•π•sqrt(L/g)

1.2 = 2 pi sqrt (L/g)

.0365 = L/ 9.8
L = .357 m
= 35.7 cm yes

I ended up with 35.746cm. Is that correct?
