Answer:

Length of the chain, l = 0.99 m

Step-by-step explanation:

Given that,

A playground tire swing has a period of 2.0 s on Earth i.e.

T = 2 s

We need to find the length of this chain. The relationship between the length and the time period is given by :

$T=2\pi \sqrt{(l)/(g)}$

Where

l = length of chain

g = acceleration due to gravity

$l=(T^2g)/(4\pi^2)$

$l=((2)^2* 9.8)/(4\pi^2)$

l = 0.99 meters

So, the length of the chain is 0.99 meters. Hence, this is the required solution.
