The planet that is the farthest is Neptune, pls make me brainliest:)
No two electrons in an atom or molecule may have the same four electronic quantum numbers, according to the Pauli Exclusion Principle. Only two electrons can fit into an orbital at a time, hence they must have opposing spins.
<h3>What is Pauli's exclusion principle ?</h3>
According to Pauli's exclusion principle, two electrons cannot share the same orbital and must have anti-parallel or opposite spins. Example: Two bonded electrons in a neutral helium atom achieve the opposite spin to occupy the lowest-energy () states.
- It is known as the exclusion principle because, in accordance with it, all other electrons in an atom are excluded from having the same set of specific values for the four quantum numbers as one electron in the atom.

The acceleration of the car is stated as -2 m/s², while the deceleration of the car is termed as 2 m/s².
Answer:
Explanation:
Acceleration exerted by any object in order of decrease in the speed is termed as deceleration. In other words , negative acceleration or acceleration acting in opposite direction to stop the motion of any object is termed as deceleration. The magnitude of acceleration and deceleration is same only the direction is completely opposite to each other. So the negative sign will be obtained for acceleration value of any object whose velocity slows down from initial velocity.
Here , the initial velocity was 60 m/s and the final velocity is slowed down to 40 m/s in time 10 s.
So acceleration = (Final velocity - Initial velocty)/Time
Acceleration = (40-60)/10 = -20/10 = -2 m/s².
Thus, the acceleration of the car is stated as -2 m/s², while the deceleration of the car is termed as 2 m/s².
Answer:
1)force:- force is an external affert by any body on an object.
2) force and motion are related to each other. force helps to create motion in any object.
3) frictional force
4) Newton
