Although the video is not found here, the sentence makes reference to the transmission spectrum of colored filters.
<h3>What is the transmission spectrum?</h3>
The transmission spectrum indicates the light portion having a given wavelength that can be passed through a filter.
This spectrum (transmission spectrum) depends on the physical separation of the particles that form the filter.
In conclusion, although the video is not found here, the sentence makes reference to the transmission spectrum of colored filters.

The answer is Anorthosite. This is a kind of intrusive igneous rock composed mainly of calcium-rich plagioclase feldspar. All anorthosites located on Earth contain of rough crystals, but some illustrations of the rock reserved from the Moon are outstandingly crystalline.
Answer: The ratio of atoms of potassium to ratio of atoms of oxygen is 4:2
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed, and remains conserved. The mass of products must be same as that of the reactants.
Thus the number of atoms of each element must be same on both sides of the equation so as to keep the mass same and thus balanced chemical equations are written.
K exists as atoms and oxygen exist as molecule which consists of 2 atoms. The ratio of number of atoms on both sides of the reaction are same and thus the ratio of atoms of potassium to ratio of atoms of oxygen is 4:2.
The forces on the y axis are:
N-mgcos(60)=0 , wich becomes
N=mgcos(60)
Rember that the friction force is always contrary to the motion of an object and its formula is f=μ * N
The forces in the x axis are:
-f + mgsin(60)= m * a
-μ*mgcos(60) + mgsin(60)=m*a ,
μ = ( m*a - mgf=μ[sin(60) )/ ( mgcos(90) )
Answer:
Explanation:
Answer C
Inertia is the resistance to change of motion.
The people in the car were already in motion when the car stopped. There was no force applied to the bodies to stop them as well until they collided with the wrecked car interior. Typically very soon after the initial collision.
