371640 Which of the following is NOT a fundamental force in nature?

371641 A physical quantity \(A\) on multiplication with velocity results in another quantity \(B\). If the quantity \(B\) is energy, then the quantity \(A\) is

371642 A body of mass \(10 \mathrm{~kg}\) has constant velocity of \(10 \mathrm{~ms}^{-1}\). A constant force is applied for a duration of \(4 \mathrm{~s}\) on the object and gives it a speed of \(2 \mathrm{~ms}^{-1}\) in opposite direction. Then, find acceleration produced in it.

371643 Five objects of different masses are simultaneously released vertically downwards from height ' \(h\) ' (in air). Which physical quantity associated with the objects will change at the instant they strike the ground? (neglect the air resistance.)
