Answer:

An atom consists of protons, electrons, and neutrons.

Explanation:

The atom of an element is its smallest indivisible particle that retains its chemical properties. Atom is the fundamental and basic unit of matter.

The structure of an atom is made up of a positively charged PROTON, a neutrally charged NEUTRON (both contained in the nucleus) and a negatively charged ELECTRON that surrounds the nucleus. These three particles are called sub-atomic particles. The arrangement and number of these sub-atomic particles determine the properties of the atom.

What are the three examples to justify Newton first law of motion .

Sergeu [11.5K]

Explanation:

1.Law of Inertia

Inertia : is the ability to resist change in motion.

Example; if you roll a ball it will keep running unless you change it's direction with the help of friction..

2. second law of motion states that an object will accelerate when an unbalanced force is applied on a mass..

unbalanced force is a type of force where total force≠zero, means the object will move..

Example; if you will try to push a truck will be less but if you push a car the acceleration will be more.. because car has less mass..

3. the third law of motion state that foreign every action there is a opposite reaction..

Example; can you throw a ball on the floor ...the floor pushes back that the ball..
