Q2. You travel to an alien planet. The local population tries very hard to tell you what gravity is on the surface. You cannot understand them, and do not have a tool to calculate gravity directly. You also ran out of water. They offer a liquid to you, other than you don't know what it is. Your ill-prepared journey, however, may not be the total loss. Is there a way to measure the density of the liquid if you have a block of balsa-wood (170 kg/m^3) that is 10cm x 10 cm x 10cm and a good ruler? Describe why or why not. Include any relevant numbers.
