Question

I need to finish this project...I'd greatly appreciate any help

Answer 1

the weight will not affect the period

a longer string will though

Answer 2

well i don't even to look at it,

given the equation for the period of a pendulum:

T = sqrt(l/g)

where
l is the length of the string,
g is gravitational force

you can see that weight of the pendulum has no bearing on period.

Answer 3

Thanx :)
