Apaleotndologist finds a bone that might be a sauropod’s bone. in the laboratory, she finds that the carbon-14 found in the bone is 1/10 of that found in a living bone tissue. could this bone have belonged to a sauropod? explain your reasoning. (hint: the sauropods lived from 200 million years ago to 145 million years ago. the constant for carbon-14 is 0.00012.)
a.) no, because the amount of carbon-14 found indicates a period before the sauropods even came into existence.
b.) no, because the amount of carbon-14 found indicates a period after the sauropods became extinct.
c.) yes, because the number of years calculated is in the range of 200 million years and 145 million years ago.
d.) yes, because the amount of carbon-14 found in the bone is one-tenth of that found in a living bone tissue.

  b.)  No, because the amount of Carbon-14 found indicates a period after the sauropods became extinct.

Step-by-step explanation:

The amount of time corresponding to the fraction found satisfies the equation ...

  1/10 = e^(-0.00012t)

  ln(1/10) = -0.00012t . . . . . taking natural logs

  t = ln(1/10)/-0.00012 ≈ 19,200 . . . . years

19000 years is much different from 145 million years, so the bone will be much different from a sauropod bone. The bone found is from a time later than the last living sauropod.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
