Answer:

Explanation:
The index of refraction is equal to the speed of light c in vacuum divided by its speed v in a substance, or
. For our case we want to use
, which for our values is equal to:

Which we will express with 3 significant figures (since a product or quotient must contain the same number of significant figures as the measurement with the <em>least</em> number of significant figures):

Option C
In nuclear fission and fusion the mass defect is the mass lost during the reaction that is converted into energy
<u>Explanation:</u>
Mass defect is the contrast within the estimated mass of the released system and the empirically estimated mass of the nucleus. The nuclear binding energy is acknowledged as mass, and that mass enhances "missing".
This missing mass is described as a mass defect, which is nuclear energy, also acknowledged as the mass discharged from the reaction as any trajectories. The mass defect of a nucleus depicts the mass of the energy adhesive of the nucleus and is the variation amidst the mass of a nucleus and the entirety of the masses of the nucleons of which it is comprised.
well It gets squeeze together so tightly that four hydrogen nuclei combine to form one helium atom. This is called nuclear fusion. In the process some of the mass of the hydrogen atoms is converted into energy in the form of light. The same process occurs in thermonuclear (fusion) bombs.
Answer:
No, there wasn't any variation in the light intensity at 360 degrees.
During the rotation, rotating through an angle of 90° gradually brought the intensity to a maximum. Rotating by another 90° degrees brought the intensity to a minimum at some point. Rotating by another 90° brought it back to its maximum and then another 90° brought it to its initial intensity.
