Final answer:
This physics question involves uniform circular motion where an object moves uniformly around a circular path with a specific radius and period. The essential concepts to understand include speed and centripetal acceleration.
Step-by-step explanation:
The subject of this question is Physics, specifically dealing with uniform circular motion which involves an object moving along a circular path at constant speed. The key parameters associated with uniform circular motion include the radius of the path, the time it takes to complete a revolution (period), and the associated centripetal acceleration.
In this case, we are given a radius of 20.0 cm and a period of 2.00 seconds for one complete revolution. To find the speed of the object, we can use the formula v = 2πr/T, where v is the linear speed, r is the radius of the circular path, and T is the period of revolution. Furthermore, the centripetal acceleration can be found using a₁ = v²/r, where v is the linear speed.
