Answer:
The length of the pendulum is 14.13 meters.
Step-by-step explanation:
The length of a pendulum is given by the formula,
, where T is the times period and L is the length of the pendulum.
Now, given that T = 2.4π seconds.
So, from the above equation, we get,
![2.4\pi = 2\pi \sqrt{\frac{L}{g} }](https://tex.z-dn.net/?f=2.4%5Cpi%20%20%3D%202%5Cpi%20%20%5Csqrt%7B%5Cfrac%7BL%7D%7Bg%7D%20%7D)
⇒ ![\sqrt{\frac{L}{g}} = 1.2](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7BL%7D%7Bg%7D%7D%20%3D%201.2)
⇒
{We have the value of g as 9.81 m/sec²}
⇒ L = 1.44 × 9.81 = 14.13 meters. (Approx.)
Therefore, the length of the pendulum is 14.13 meters. (Answer)

Step-by-step explanation:
Convert to a mixed number by placing the numbers to the right of the decimal over
100
. Reduce the fraction. Then, convert the mixed number to an improper fraction by multiplying the denominator by the whole number and adding the numerator to get the new numerator. Place this new numerator over the original denominator.
