state teh effect if any on the period of the pendulum when
a)a heavier pendulum bob of the same size is used
b)there are a larger number of oscillations
c) there is a smaller angle of swing
d)a longer pendulum is used
assuming all otehr factors are constant
TIA
For question c, angle displacement actually does affect the period of pendulum swing. It's due to some air resistance blah. But in theory, you gotta stick to conventions, and that's the period remains the same.
