Answer the following question regarding field of view measurements. Enter your answer as a whole number (decimal format).
Imagine you are using a microscope where the diameter of the field of view at 4x is 10mm. You view the microbe below at 100x.
What is the size of each individual microbe? DO NOT ADD UNITS.
D1=4x and M1=5mm
Carbon-14 is constantly being produced in the upper atmosphere, and the amount is in
equilibrium. As long as an organism is alive, it keeps its carbon isotopes in balance with the
atmosphere, but at soon as it dies, it stops taking up new 14C, and so the geologic clock starts.
You found a shell buried in sedimentary layers, which has 6% of its original 14C left.
Determine the age of the shell. Show your work.
PROBLEM SOLVING: Express your answer to the fourth decimal places. Show complete solution.
Box your final answer.
1. A wooden object found in an Indian burial ground and subjected to radiocarbon dating.
The decay rate associated with C-14 is 10 disintegrations per minute per gram carbon.
What is the gge of the obiect?

- Please help me with this question. A=.2arrow_forwardI need to know the number of years! There is only one part to this question. The pictures show the "Figure" and "Bar charts" tabs and the "Graph" tab says this: A curve showing the percentage of radioactive atoms remaining in a mineral sample is graphed on a coordinate plane. The horizontal axis, labeled "Age in half-lives," ranges from 0 to 6. The vertical axis, labeled "Percentage remaining," ranges from 0 to 100. The curve enters the viewing field with a negative slope at (0, 100). The magnitude of the negative slope is progressively reduced such that it is nearly horizontal as it exits the viewing field at (6, 0.02).
