Answer:
I = mgd/4π²f²
Explanation:
The period of the physical pendulum T = 1/f where f = frequency,
T = 1/f = 2π√(I/mgd) where I = moment of inertia of the physical pendulum, m =mass of pendulum, g = acceleration due to gravity and d = distance of center of mass of pendulum from pivot point.
1/f = 2π√(I/mgd)
dividing both sides by 2π, we have
1/2πf = √(I/mgd)
squaring both sides, we have
(1/2πf) = [√(I/mgd)]²
1/4π²f² = I/mgd
multiplying both sides by mgd, we have
I = mgd/4π²f²

Time dilation is the slowing of the passage of time at high speeds. The faster the object moves, the greater the amount of time dilation. Time dilation, in part, accounts for the constant speed of light, regardless of the light's source and regardless of the observer's perspective.
