If the period of a simple pendulum is t and we increase its length so that it is four times longer, what will the new period be? t/4 it is unchanged. t/2 2t 4t

2T

Explanation:

The period of a simple pendulum is:

T = 2π √(L/g)

If L is increased by a factor of 4, then:

2π √(4L/g)

4π √(L/g)

2T

So the period is doubled.

vestigial organs (like your appendix) are organs that no longer serve a purpose.
