I) a magnifying glass
A concave lens is called diverging lenses because they cause parallel rays to diverge. The convex lens is curved towards the inside. The concave lens is curved towards the outside. It is used to correct long-sightedness or hypermetropia.
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.
