Answer:
Explanation:
Tension provides centripetal force in the circular motion . In circular motion work done by force = torque x angle
torque is zero as , centripetal force passes through axis of rotation that is center.
So work done by centripetal force = 0
So work done by tension on M = 0

Answer:
The acceleration of the wallet is 
Explanation:
Given that,
Radius of purse r= 2.30 m
Radius of wallet r'= 3.45 m
Acceleration of the purse 
We need to calculate the acceleration of the wallet
Using formula of acceleration

Both the purse and wallet have same angular velocity








Hence, The acceleration of the wallet is 
False. I’m pretty sure the heart is the strongest muscle ( ._.)
