The sun is the center of the solar system which is surrounded by the nine planets and they tend to orbit the sun in concentric circles with the sun as the center.
<h3>What is the solar system?</h3>
The term solar system has to do with the arrangement of the sun and the planets. The sun lies at the focus of the solar system. Now we know that there are nine planets that orbit around the sun. The distance between the planets and the sun depends on their relative proximity to each other.
Thus, the sun is the center of the solar system which is surrounded by the nine planets and they tend to orbit the sun in concentric circles with the sun as the center.

Explanation:
Given that,
Mass of the planet Krypton, 
Radius of the planet Krypton, 
Value of gravitational constant, 
To find,
The acceleration of an object in free fall near the surface of Krypton.
Solution,
The relation for the acceleration of the object is given by the below formula as :
So, the value of acceleration of an object in free fall near the surface of Krypton is 
The answer is:
It is a measure of the strength of the bonds between ions.
Lattice energy is an estimate of the strength of the bonds formed by ionic compounds.
The first two choices are wrong because it is actually the opposite.
- As the ion size increases, lattice energy <u>decreases</u>.
- As charge of ions increases, lattice energy <u>increases</u>
As for the other third option, it is wrong because lattice energy is the energy RELEASED not absorbed.
