Answer is: 12,6% (1/8) <span>percentage of the sample will remain.
</span>c₀ - initial amount of C-14.<span>
c - amount of C-14 remaining
at time.
t = 5700</span> y.<span>
First calculate the radioactive decay rate constant λ:
λ = 0,693 ÷ t = 0,693 ÷ 5700</span> y = 0,000121 1/y = 1,21·10⁻⁴ y.
c = c₀·e∧-λ·t.
c = 2000 · e∧-(0,000121 1/y · 17100 y).
c = 252 g.
ω = 252 g ÷ 2000 g = 0,126 = 12,6%.

Answer:
Gravitational potential energy - into Kinetic energy
Explanation:
Atoms “stick” to each other because they all try to get into a noble gas configuration. Which simply means that they try to reach a amount of electrons equal to noble gasses, this property makes simple atoms like water stable. I hope this helps! Have a great day and stay safe!
