The number of atoms that remains at the said time is 3.76 * 10^11 atoms of Cl-36 and 2.62 * 10^12 atoms of Ar-36.

The term half life is used to explain the time taken for only half the number of radioactive atoms to remain.

Given that;

No = 3 * 10^12 atoms

t1/2 = 3.01 8 10^5 years

t = 9.03 * 10^5 years

Thus;

k = 0.693/3.01 * 10^5

=2.3 * 10^-6 year-1

Now;

N=Noe^-kt

N = 3 * 10^12e^(2.3 * 10^-6 * 9.03 * 10^5)

N = 3.76 * 10^11 atoms

Which objective is referred to as the "scanning objective"?

Y_Kistochka [10]

Answer:

This question lacks options; they are:

a. 4x b. 10x c. 20x d. 100x

The answer is A

Explanation:

The objective lens is an integral part of a light microscope as it provides the viewer with the picture or image of the specimen. There are several types of objective lens depending on their magnification.

The lowest possible objective lens with the power of 4x is called the SCANNING OBJECTIVE. In combination with the eye/occular lens, it provides a magnification of 4x × 10 = 40x. The name of this lens comes from the fact that it provides a full scan of every part of the specimen being viewed before diversifying into a specific region by changing the objective.
