Answer:
The radius of a chamber is 2.36 meters.
Explanation:
Given that,
The outer wall moves at a speed of 2.72 m/s.
Mass of the person, m = 75.1 kg
The person feels a force of 235 N force pressing against his back. The force acting on the person is centripetal force. It is given by the below formula :

r is the radius of a chamber


r = 2.36 meters
So, the radius of a chamber is 2.36 meters. Hence, this is the required solution.
As the banana flies through space, up the red arrow showing its path of motion takes a curved or parabolic shape.
<h3>What is a projectile?</h3>
A projectile is an object launched into space at an angle to the horizontal ground and allowed to fall freely under gravity.
The path of motion of a projectile is parabolic.
Examples of objects that are projectiles include:
- A thrown banana
- A kicked football
- An arrow shot from a bow
Therefore, as the banana flies through space, up the red arrow showing its path of motion takes a curved or parabolic shape.

The first reason is that in the past humans didn't necessarily see the connections between the oceans and thus labelled them that way separating them into 5 oceans and the names stuck to this day.
Secondly, while all the oceans of the world constitute one large Ocean, people need some way to identify each part of it since it is easier to think when we have different categories instead of one large category.
