A plank of wood with a density of ρw = 650 kg/m3 and volume V = 0.65 m3 is floating in the ocean. (Assume the density of salt water is ρs = 1100 kg/m3) What is the volume of the block that is submerged? A) 0.23 m3 B) 0.38 m3 C) 0.42 m3 D) 0.51 m3 E) 0.56...

A balloon has a volume of 1000 m3 and a mass of 500 kg when empty. When full of helium, what is the maximum mass it can lift off the ground? The density of helium is 0.18 kg/m3 and the density of air is 1.29kg/m3.
