How old is a piece of cotton cloth if the half-life of carbon-14 is 5,730 years, and the carbon-14 composition of the cloth is 22 percent that of living plants? options: A) 12,517 years B) 1.21 × 10^-4 years C) 1,813 years D) 1.21 × 10^-4 years^-1 33 points and a quick answer pretty please

If C is critical angle, then

sinC=

n

1

, where n is refractive index of the material.

Now, n =

2

, therefore ,

sinC=

2

1

Then, C =45

∘

is has three carbons, so the answer is propylamine.
