Answer: The atomic number is the number of protons in an atom, and isotopes have the same atomic number but differ in the number of neutrons. The number of protons in an atom is called its atomic number. This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms.

Mass of Derrick at a height 4.3 m having 2730 joule of energy is 65 Kg.
<h3>What is the expression of gravitational potential energy near the earth surface?</h3>
- Mathematically, gravitational potential energy near the earth surface= m×g×h
- m= mass of Derrick, g= acceleration due to gravity, h= height at which Derrick present
- Then, mass (m) of Derrick = potential energy/ (g×h)
<h3>What is the mass of Derrick, if he gains 2730 joule of energy at 4.3m above the ground?</h3>
Mass of Derrick= 2730/(9.8×4.3)
= 65 kg
Thus, we can conclude that the mass of Derrick is 65 Kg.
