Scientists discover two planets orbiting a distant star. The average distance from the star to Planet A is 4 AU, and it takes 43

Answer:

C. 9 AU

Explanation:

The period (T) of Planet A is 432365=1.2 Earth years. The period of Planet B is 1,458365=4.0 Earth years. Kepler's Third Law states that

a3=kT2

Substituting the known values of a and T for Planet A, we have

43=k⋅1.22

64=k⋅1.4

k=45.7

Using this value for k, we can solve for the distance from Planet B to the star

a3=45.7⋅4.02

a3=731.2

a=9.0AU

An alternative solution is to notice that a3T2=k for both orbits, which means that the ratio a3T2 is the same for both orbits. So, 434322=x314582. Solving this proportion gives x3=729, so x=9.0AU.

Which of the following statements concerning prokaryotic cells are true? Check all that apply.
Firdavs [7]

Answer:

They are typically smaller than eukaryotic cells.

The DNA of a prokaryotic cell is contained in the nucleoid.

Explanation:

There are several ways in which prokaryotic cells are different from eukaryotic cells. Firstly, they are generally smaller in size, their organelles are not membrane bound, and they have no nucleus. They, however, share commonalities with eukaryotic cells including the presence of a bilipid plasma membrane, presence of ribosomes and DNA.
