Name the metal that burns in oxygen with a dazzling white flame
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 )
