The amount of sugar in a liquid can be measured using a laser pointer and a prism. Basically, you utilize Snell's Law:
n_i*sin(θi) = n_r*sin(θr), where,
n_i = index of refraction of the incident medium
n_r = index of refraction of the refractive medium
θi = <span>angle of incidence
</span>θr = <span>angle of refraction
</span>
You make use of the laser pointer, prism, and sugar solutions in various known concentrations. You then graph the sugar concentration versus the angle of refraction. You can then determine the amount of sugar in a liquid after determining the angle of refraction of that unknown sugar solution.
Answer:
The answer to your question is: letter B
Explanation:
The information given is showing us three kinds of carbons and their respective number of protons and neutrons. Now, let's analize the options given:
A.)Carbon Bond Types This option is about trhe kind of bonds carbon is able to form like single, double or triple and is different from the information descrive above. So ,this option is incorrect.
B.)Carbon Isotopes is option is about the carbon atoms that have the same number of protons and different amount of neutrons exactly as it is describe above, to this option is correct.
C.)The Carbon Cycle
this option is about how carbon goes from one kind of matter to another and is completely different to the description given above, so this option is incorrect.
D.)Chemical Reactions this option is about reactants that after a process give products they could be from carbon -12, carbon-13 or carbon-14 and other elements, so this option is different from the description given above.
Answer:
ionic bond
Explanation:
cation calcium looses 2 electrons to bond with two iodine atoms to form CaI2 (Calcium Iodide)
Answer:
C. Work and time
Explanation:
Power is the rate work is done, so this would involve how long it would take to do a certain amount of Work and it is also the measure of the transfer of energy over a period of time.
The formula for power is:
Where:
P = Power
W = Work
t = time
