Newton's first law says that an object at rest will stay at rest, while an object in motion will stay in motion unless acted upon by an outside force.
A great example of this is a ball sitting on the ground. The ball will not move until some force is used on it, rather that be you kicking it, the wind blowing it, etc. Once that force is used against it, the ball will continue to move until gravity, air resistance, a friction bring it to a stop.
It shows the first law of Newton.
The first law states that :-
'If an object is at rest it will be at rest or if it is at motion, it will be in the state of motion until an external force is applied'
Since the airplane is at rest, it will be at rest showing the first law
Answer:
C
Explanation:
Rocks with hotter temperatures sank to the bottom of the Earth. The rocks with the hottest temperature became the core and the rocks with the least amount of heat became the crust.

Answer:
Atoms are electrically neutral because there are an equal number of protons in the nucleus and In the cloud around the nucleus.
Explanation:
- The atoms that are the building block of matter consist of protons, neutrons, and electrons.
- The protons are positively charged and the electrons are negatively charged particles.
- The neutrons are negatively charged particles.
- The atoms in its stable natural state consist of an equal number of protons and electrons.
- Thus an atom has a neutral charge in its natural state.
