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
In determining the least count of the main scale in the Vernier caliper, which of the following
method must be followed? *
O Divide the difference between two adjacent main scale values by the number of divisions between them.
O Divide the least count of the main scale by the number of division of the Vernier scale.
Multiply the least count of the Vernier scale by the number of Vernier division that is aligned with the main scale
mark.
O Read the main scale mark just before the zero mark of the Vernier scale.
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.
