The correct answer is C. Mercury and Mars have the same gravitational force
Explanation:
This chart compares the different features of two planets in our solar system (Mercury and Mars). In this chart, the only numerical value or feature that is the same for both planets is gravity because for both planets gravity is 1.7 m/s2. This implies the gravitational force or the force that attracts objects towards the center of the planet is the same or that objects are pulled with the same force in both planets. Moreover, this factor depends on others such as mass, density, among others.
<span>The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. The "electromagnetic spectrum" of an object is the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. Hope this helped.</span>

Explanation:
Answer: B
The immense volume of matter
Explanation:
Stars are formed by cloud and dust, draw together by gravity.
But the longevity of a main sequence star lives depends on how massive it is. An enormous massive star burns faster due to its enormous material it contains and higher core temperatures caused by greater gravitational forces. While a less massive star will burn slowly and stick around the sun for a very long period. The structure of a main sequence star like our sun can therefore hold for a long time because of the immense volume of matter of star.
