How does knowing the half-life of Carbon 14 can tell scientists the absolute age of a rock sample? Can you please explain that to me? Thank you.

Carbon-14 dating is not used for rocks, it is used for dating biological samples.  The ratio of Carbon-14 to the other forms of carbon is essentially constant while a plant or animal is alive because the carbon-14 is replenished from the atmosphere.  That stops when the plant or animal dies and the carbon-14 starts to decaying at a fixed rate while the other forms do not.
I've noticed you have been posting a lot of questions like this. Let's keep in mind the EE "Homework Policy," people...

"I think that half-life of Carbon 14 CAN tell scientists the absolute age of a rock sample."
nevertheless it cannot.
(but there are other radioactive decays which can)
Maybe young rocks containing biological material?
Is amber considered rock?
