Answer:
The heavier something is, the harder it is to slow down. As such, higher amounts of mass result in a lower rate of slowing.
Independent- nose of the airplane
dependent - paper clips
control - how many paper clips
It's a normal force exerted by the floor. It balances the gravitational force. Option A is correct. The normal force is balanced by the gravitational force.
<h3>What is the friction force?</h3>
It is a type of opposition force acting on the surface of the body that tries to oppose the motion of the body. its unit is Newton (N). Mathematically it is defined as the product of the coefficient of friction and normal reaction.
On resolving the given force and accelertaion in the different components and balancing the equation gets components in the y-direction.
The normal force is balanced by the gravitational force. It's a normal force exerted by the floor. It balances the gravitational force.
Hence, option A is correct.

There is a possibility but not extremely likely
As per question the initial states of the gases are given as
INITIAL STATE: FINAL STATE:
![v_{2} =3v[say]](https://tex.z-dn.net/?f=v_%7B2%7D%20%3D3v%5Bsay%5D)

AS per combined gas equation obtained from the combination of Boyle's law and Charles law [Basic ideal gas laws]

Hence
