Pendulum question

[Thomas Nguyen]

I can't find the formula to represent the relationship between l and P in question b/,

Have you plotted the points? Desmos is a graphing program you can download. Or you could use a graphics calculator. Or you could use Excel.

You are being asked to derive that formula by investigating the plotted graph from the given set of data.

I've tried it as well, got all the points. i tried y=0.2√x an it kinda fits into the points

like coming up with a formula? i got y=0.2√x estimated?

Now put that (y=0.2 * √x) in terms of 'l' and 'P'

Can you have a look at c) ii) please. I know that the similarity is both are in the form of y=a√x . But I dont know how to put the words to describe the differences

Please state Galileo's equation (formula) for simple pendulum.
