Spectroscopy is the study of the absorption and emission of light and other radiation by matter.

<h3>How can we conclude the statement?</h3>

Spectroscopy is the interaction of lights and atoms and the study of the emission and absorption of light.

Spectroscopy can be defined as the study of light absorption as well as its emission. It is also uses to study of structure of atoms.

It offers techniques that has to do with how a sample responds to the radiation of light.

Its applications are:

  • Used to determine atomic structure To determine metabolic functions
  • studies spectral emissions
  • Helps to improve the effectiveness of drugs

Which scenario describes the damage caused by a tornado?
9966 [12]

The answer is a path of destruction up to 50 miles long with destroyed trees and homes.

Tornadoes form from severe thunderstorms. Wind in the higher altitude of the storm moving at a greater velocity than wind at a lower altitude creates a vertical wind shear. The faster-moving winds aloft come from the west and create an updraft when they meet slower-moving wind close to the ground that is moving in the opposite direction. As warm surface air moves upward into the thundercloud, the rotating air creates a vortex.

The image below shows before and after damage of a tornado.

Scientists experimenting with two charged objects of 2.56 x 10-6 C and 3.34 x 10-7 C displayed a repulsion of 2.26 x 10-3 N. How
Pachacha [2.7K]

Answer:

The objects were 1.8m apart.

Explanation:

We will start stating the Coulomb's Law. It says that:

F_e=\frac{Kq_1q_2}{r^{2}}

Where F_e is the electric force between the objects, q_1 and q_2 are the magnitude of the charge of the objects, r is the distance between them and K is the Coulomb's constant (K=8.9*10^{9} \frac{Nm^{2} }{C^{2} } in vacuum). Solving for the distance r we have:

r=\sqrt{\frac{Kq_1q_2}{F_e} }

Plugging the given values into this equation, we obtain:

r=\sqrt{\frac{(8.9*10^{9}\frac{Nm^{2} }{C^{2} })(2.56*10^{-6}C)(3.34*10^{-7}C)}{2.26*10^{-3}N}}=1.8m

In words, the two charged objects were 1.8m apart.
