4. Why isn't full employment the same as zero unemploy-<br>ment?​
Marina CMI [18]

Explanation:

Structural: This is a type of unemployment due to a change in demand or skill. ... Full employment is the same as zero employment because full employment is reached when there is no cyclical unemployment in the US. Zero unemployment is the idea where everyone is working and not one person doesn't have a job.

What is refractive index​
BARSIC [14]

Answer:

Explanation:

In optics, the refractive index of a material is a dimensionless number that describes how fast light travels through the material. It is defined as where c is the speed of light in vacuum and v is the phase velocity of light in the medium or for short the ratio of the velocity of light in a vacuum to its velocity in a specified medium.

In about 5 billion years, at the end of its lifetime, our sun will end up as a white dwarf, having about the same mass as it doe
vitfil [10]
It is fine to use the equation given by Plitter, since we are told that the mass is about the same as it is now, and I seriously doubt the original question wants the student to go into relativistic effects, electron degeneracy pressure and magnetic effects that govern a real white dwarf star.
There is no need to make it unnecessarily complicated, when the question is set at high school level.  The question asks, given a particular radius, and a given mass, what will the density be (which in this case will be the average density).   To answer the question, one needs to know the mass of the sun (which is about 2×1030 Kg.  One needs to convert the diameter to a radius, and then calculate the spherical volume of the white dwarf.  Then one can use the formula given above, namely density=mass/volume
