What is the relationship between mass, volume, and density? What is the relationship between mass, volume, and density? Density
1 answer:
Answer:
A. Density is proportional to mass and inversely proportional to volume
Explanation:
Density can be defined as the property that matter has, whether solids, liquids or gases, to be compressed in a given space.
The expression that relates the density with the another values is given by,
Where,
(It is directly proportional to the mass of the object)
(It is inversely proportional to the volumen of the object)
<em>Therefore density is directly proportional to the mass and inversely proportional to the volumen.</em>

Kepler's third law is used to determine the relationship between the orbital period of a planet and the radius of the planet.
The distance of the earth from the sun is .
<h3>What is Kepler's third law?</h3>
Kepler's Third Law states that the square of the orbital period of a planet is directly proportional to the cube of the radius of their orbits. It means that the period for a planet to orbit the Sun increases rapidly with the radius of its orbit.
Given that Mars’s orbital period T is 687 days, and Mars’s distance from the Sun R is 2.279 × 10^11 m.
By using Kepler's third law, this can be written as,
Substituting the values, we get the value of constant k for mars.
The value of constant k is the same for Earth as well, also we know that the orbital period for Earth is 365 days. So the R is calculated as given below.
Hence we can conclude that the distance of the earth from the sun is .
