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 .

This question is true because it just is
The examples where using conservation of energy to solve a problem is easier than other methods are:
1. Pendulum
2. Nuclear Power Plant
The principle of the conservation of energy says that:
Energy within an isolated system is neither created nor destroyed, it simply changes from one type of energy to another.
1. Pendulum:
As the pendulum swings down:
gravitational potential energy of the pendulum →kinetic energy of the pendulum.
As the pendulum swings up: kinetic energy of the pendulum→ gravitational potential energy of the pendulum.
2. Nuclear Power Plant:
Nuclear energy (from the decay of uranium) → thermal energy of water
→kinetic energy of a turbine →electrical energy + thermal energy (from friction in the turbine and transmission lines)
