Answer: (P2/P1)=(T2/T1)
(P2/1200.0kPa)=(387/283)
P2=(387K/283K) * (1200kPa)
P2= 1641kPa
Explanation:
Scientists use radioactive decay to date fossils and artifacts through a process called "carbon dating," which measures the amount of carbon still left in a dead object. The less carbon that exists, the longer that animal or plant as been dead.
Pretty sure the answer is 23^4-20=54
