For question 13b how would I figure out that the total energy includes the work done against air resistance? it makes sense its just I struggle with logic.

Sir about question 9, as viscosity decreases, and as you mentioned terminal velocity is constant, how is drag force also constant? (Calculating from equatin 6 * Pi * Radius * Viscosity * Velocity if viscosity decreases and terminal velocity is constant, shouldn't drag force also decrease accordingly?)

thanks a lot for helping us. can you please help in understanding 12b graph for direction of acceleration by method 2. why acc is there and be positive

[sharadevilinage]

in question 12 b why is the graph drawn in the negative side if the person falls with gravity and not against

Sir in Q9 as viscosity decreases shouldn't drag force also decrease?
