2) The Executive Branch
3) The Judicial Branch
This question asks us to provide the hierarchy of the executive branch. The hierarchy of the Executive Branch includes the following elements:
- The President
- The Vice President
- The Executive Office of the President
- The Cabinet
The complete hierarchy in detail is attached as an image.
The apparent brightness is defined by how much light we get pretty much. The formula is:
This takes into account that the light is spreading out to a sphere that has the surface given by 4πd^2.
We have that d=20 ly and 1 ly is 9.46*10^12 km or 9.46*10^15m.
Hence, d=20*9.46*10^15=189.2 *10^15 m
Now, we can substitute the d value and calculate that L=<span>8.45184*

<h2>Right answer: It is used to measure long distances in space</h2>
A light year () is a distance unit that is approximately
.
By definition it is <em>the distance that a photon would travel in vacuum during a Julian year (365.25 days) at the speed of light (299 792 458 m/s) at an infinite distance from any gravitational field or field magnetic. </em>
<em> </em>
In other words:
It is the distance that light can travel in a year.
This unit is used to measure large distances in space. Therefore the correct answer is D.
