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.
Ion-dipole force is involved in the chemical reaction above.
Explanation:
We need to apply the conservation law of linear momentum to two dimensions:
Let
= momentum of the 1st ball
= momentum of the 2nd ball
In the x-axis, the conservation law can be written as

or

Since we are dealing with identical balls, all the m terms cancel out so we are left with

Putting in the numbers, we get


In the y-axis, there is no initial y-component of the momentum before the collision so we can write

or

Taking the ratio of the sine equation to the cosine equation, we get

or

Solving now for
,
