Draw the curve for determining the value of g using compound pendulum.

Given that,

Acceleration due to gravity = g

Time period :

Time period is defined as,

Where, l = length of pendulum

g = acceleration due to gravity

We need to calculate the value of g

Using formula of time period

Where, T = time period

l = length of pendulum

Hence, The value of g is

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.  

it has to be b, about 97 percent.
