Figure below shows water levels in a measuring glass before and after a piece of wood of 100 g is put into the water.
a) Calculate the density of wood, if only half of the wood sinks into the water? (2 Points)
b) If we use oil instead of water and the density of oil is 0.9 times smaller than the water, how high will the level of oil increase if you drop the wood to the oil? Give your reason. (2 Points)
