The system shown in the figure is in equilibrium. The metal spheres are identical and each has a mass of 2 kg. The surface areas of the pistons are equal and 100 square centimeters each. The density of water is 1 g per cubic centimeter. Assuming that the frictions and masses of the pistons are negligible, what is the mass of G? ( g = 10N/kg )
1621if 100W and 200W bulbs are connected in series to a supply which bulb will glow brighter and why
5 25053A 100W bulb and 60 bulb both rated at 220V are connected in series across 220V supply. If 60W bulb is removed and only 100W bulb remains in the circuit, will illumination increase or decrease?
