An artifact originally had 16 grams of carbon-14 present. the decay model upper a equals 16 e superscript negative 0.000121 ta=16e−0.000121t describes the amount of carbon-14 present after t years. use the model to determine how many grams of carbon-14 will be present in 90769076 years.

After 9076 years, there are present 5,34g of ¹⁴C

Explanation:

The radioactive decay of ¹⁴C is:

¹⁴C → ¹⁴N + β

Kinetic decay model take the form of:

A = A₀ exp(-kt)

Where A is the concentration of ¹⁴C after t time

Based on the given data:

A = 16 * exp(-0.000121*9076) = 16(0.3335) = 5,34g

After 9076 years, there are present 5,34g of ¹⁴C

I hope it helps!

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
