Please solve the C part in detail.
As this question solution is already present in Bartleby but the solution is not completely understood. So please solve part C step by step with proper reasons. The links to the solution are also giving to you. Please see it and tell me why and how in this solution part c the time period equation is calculated.
T=a+T/4+T/2 +T
Please tell me in detail how the time period is calculated for such a question.
