Is stone take longer for the downward motion than for the upward motion
Consider a stone thrown vertically upward. if we take friction against air into account, we see that the mechanical energy(1/2mv^2+ mgy) must decrease as a function of time. From this prove that the stone will take longer for the downward motion than for the upward motion
Michlson interferometer
A particle executes linear some with an amplitude if 2 cm.when the particle is at 1cm from the mean position the magnitude of its velocity is equal to that of its acceleration.Then
Which of two, namely potentiometer and voltmeter is preferable to calculate the emf of a batter? Why? When is the series combination of cells advantageous and why?
The property of liquids (or gases) by virtue of which a backward dragging force (viscous drag) acts tangentially on the layers of the liquid in motion and it tries to stop the moti
There are imaginary lines or path of the field in the given direction. The lines of force are assumed to make a closed path beginning from N pole and ending at S pole with no loss.
