*v=c/λ
λ = 3*10^8 m/s /1.97 *10^15
λ = 1.5 *10^-7
The calculated wavelength is in unit of meter. use the relationship between meter and nanometer to convert to the correct units.

Mr. Summers observed that kids with hot dogs are happy. This observation led to a hypothesis that hot dogs must make kids happy.
Maslowich

Given what we know, we can confirm that since Mr. Summers has to test a hypothesis, his next step should be to design an experiment.

<h3>Why design an Experiment?</h3>
  • The next step is to design an experiment.
  • This is because Mr. Summers has already made an observation and created a problem.
  • He must now gather data to be analyzed.
  • In order to do this, he must first design and perform an experiment.

Therefore, we can confirm that Mr. Summers must design an experiment given that this is the best way to gather data in order to be analyzed in the future and draw a valid conclusion.

How does the highly reactive nature chlorine contribute to the creation of ozone holes in the upper atmosphere?
liberstina [14]
Chlorine is a halogen and is very reactive and unstable. If released in an elemental form (Cl2), it would react with other substances immediately. However, <span>chlorofluorocarbons (CFCs) which contain chlorine are unreactive and when released they eventually end up in the upper atmosphere still "intact". In the upper atmosphere, sunlight is more intense and is able to break apart CFC, releasing the highly reactive chlorine which in turns destroys ozone which is more abundant in the upper atmosphere (stratosphere). </span>

in a typical person, the level of glucose is about 85 mg/ 100 mL of blood. if an average body contains about 11 pt of blood, how
Vanyuwa [196]

Let's note that 1 pint = 473.1765 mL, so 11 pints should be 5204.9415 mL.

We make a proportion out of the word problem

(85 mg glucose/ 100 mL) times (1 g/ 1000 mg) = 4.4242 grams of glucose
