There is a question: put a 10 cm long solid cube gently into a beaker full of water (here I ask the first question, is it completely submerged?). When the wood block is still, 600 g of water will overflow from the beaker (the second question is as our teacher said: F floating = g row = m row, g = ρ liquid (here the liquid is water) GV row, then = 1 × 10 & # 179; kg / M & # 179; 8 N / kg × 1000 × 10 ^ - 6 is equal to 9.8 N, but it can be calculated with m row g = 0.6 kg × 9.8 N / kg = 5.88 n. who can tell me how this is all the same? The density of water is the same. The volume of water discharged is the same. The first one is 1.0 × 10 & # 179; × 1000 × 10 ^ - 6 = 1 kg. The second one is 600 g = 0.6 n. why is it different!)
