WebAug 31, 2008 · I assume you mean you hear the water striking the ground 2.0 seconds after starting the water rather than "for another 2.0s". The height, after t seconds, is given by x(t)= 1.5+ v 0 t- 4.9t 2 (the 1.5 is the initial height above the ground, v 0 is the initial velocity that you want to find and -4.9 is g/2). Saying that the water strikes the ground after 2 s … Web5. In common usage "grounded" means. Connected to a conductor which I have arbitrarily deemed to be at an electric potential of 0, and which has such high capacitance that you …

However, the other portion of the wire is led under the earth. This is done in case of an accidental cut in the circuit to avoid overloading and other dangerous side effects.
