semi anThe bones of a prehistoric man found in the desert of New Mexico contain approximately 5% of the original amount of carbo
Kitty [74]

Answer:

24555 years

Explanation:

Data provided in the question:

Half life of carbon 14 = 5700 years

carbon present in the dead man = 5% of the original amount of carbon 14

Now,

let the initial Amount of carbon be 'A'

Therefore,

after half life

Amount of carbon = \frac{A}{2}

Thus,

\frac{A}{2} = Ae^{kt}

here,

k is the decay constant

t is the time = 5700 years

therefore,

1 = 2e^{k\times5700}

or

0.5 = e^{k\times5700}

taking natural log both the sides

-0.69314 = 5700k

or

k = - 0.000122

therefore,

for dead man Amount of carbon = 5% of A = 0.05A

thus,

0.05A = Ae^{( - 0.000122)t}

or

0.05 = e^{( - 0.000122)t}

taking natural log both the sides

we get

-2.995 = - 0.000122 × t

or

t = 24555.18 ≈ 24555 years

Surface tension is often described as “skin” on the surface of water. Why is it described this way?
Elan Coil [88]
Because it creates the same amount of tension for small animals as skin would. That is why some small animals can be on water without sinking. That is surface tension.
