The best way for the microscopic comparison of paint chips is the standard infrared spectroscopy technique.
<u>Explanation:
</u>
The hit and run road accidents often leave paint chips with which the forensic investigation is conducted and the complete incident is recalled. The paint chips are actually multi-layered materials with several coats of paints.
The best way to make a microscopic comparison of paint chips, infrared microscopes are used which provide spectra for each of the existing layer.
There are three main sampling techniques in the infrared spectroscopy such as Transmission, Attenuated Total Reflectance (ATR) and the specular reflectance. With this technique, scientists can better judge the consequences of the incident and provide better proofs of the crime.
Answer:
245.25 Newtons
Explanation:
the gravitational force of the earth is 9.81 N/Kg
And so to work this out you would multiply 25 by 9.81 to give you 245.25
If a main sequence star is cooling and expanding, it is entering the red giant stage. This means that the star has burned up all of it's hydrogen and is now starting to burn its helium making it cooler.
Answer:
an inhibitor of angiotensin II
Explanation:
Angiotensin, specifically angiotensin II binds to many receptors in the body to affect several systems. It can normally increase blood pressure by constricting the blood vessels but with the introduction of an inhibitor, it wouldn't bring about an increase in blood pressure.
It might slow down because it has to overcome friction
