Q. Water is in the big beaker in the figure on the left. Scale 1 reads 96 newtons, scale 2 reads 531 newtons, and scale 3 reads 0 newtons. The hanging block has a density of 10 × 10^3 kg/m3. To the nearest tenth of a newton what does scale 1 read after the block is fully lowered into the beaker of water?

Q. The power needed to operate your body is about 100 {rm watts}. Suppose your body could run on fusion power and could convert a total of 0.7 of its mass into energy. How much energy would be available through fusion? Assume your mass is 60kg.
