The speed of very slow-moving objects is measured in
kmh
ms
cms
Hence, option (C) is correct.
A very massive object travelling at 10ms-1 strikes a very light object, initially at rest and the light object moves off in the direction of travel of the heavy object. If the collision is elastic, the speed of the lighter object is
Electrons in a conductor move at very slow speed called 'Drift Speed' to produce current. The drift speed is around 10-5 m/s to 10-4 m/s which is very less indeed. Even then why do the torch light turn on instaneously on switching ?
