Carbon 14 is a naturally occurring stable

Why does gravity have a lesser than grater effect on higher altitudes?

Does the distance travelled by an oscillating mass between times t=0 and t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanation.
