Here are the solutions to the questions: Question 23: The change of displacement in a very small interval of time of a body is called its Explanation: Instantaneous velocity is defined as the rate of change of displacement over an infinitesimally small time interval. Answer: (C) Instantaneous Velocity* Question 24: The dimensional formula for power is Explanation: Power is defined as work done per unit time. Work has dimensions of Force × Displacement ([M L T^-2] × [L] = [M L^2 T^-2]). Time has dimension [T]. Therefore, Power = $[M L^2 T^-2] / [T] = [M L^
