A calibration curve requires the preparation of a set of known concentrations of CV, which are usually prepared by dieting a stock solution whose concentration is known.
Answer:
In physics and chemistry, the law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.
Explanation:
That is what I think on the subject
1. If you find shielding that blocks gamma radiation,then it will most likely also block the other two types. (as the hardest radiation)
2. When nuclear radiation enters the tube of a Geiger counter, it the excited atoms of the gas contained in the tube. (this type <span>deposits all energy into a single atom)</span>
3 The particles that make up protons and neutrons and are thought to be basic units of matter are <span>quarks.</span>
So, first off let’s look at what an independent and dependent variable is.
an independent variable doesn’t change when other variables change, therefore making it alone and independent.
a dependent variable changes based on other variables.
so, i don’t have enough information on your experiment to know the answer but think to yourself, what is changing over time based on something else changing (dependent variable) or think does this thing stay the same no matter what (independent variable).
hope this helps!
