The heart of a man pumps $$5~\text{L}$$ of blood through the arteries per minute at a pressure of $$150~\text{mm}$$ of mercury. If the density of mercury is $$13.6\times10^{3}~\text{kg/m}^{3}$$ $\mathrm{and}{}^{}$ $$g = 10~\text{m/s}^2$$, then the power of the heart in watt is:
1. $$1.70$$
2. $$2.35$$
3. $$3.0$$
4. $$1.50$$

The approximate depth of an ocean is $$2700~\text{m}$$. The compressibility of water is $$45.4\times10^{-11}~\text{Pa}^{-1}$$ and the density of water is $$10^{3}~\text{kg/m}^3$$. What fractional compression of water will be obtained at the bottom of the ocean?
1. $$0.8\times 10^{-2}$$
2. $$1.0\times 10^{-2}$$
3. $$1.2\times 10^{-2}$$
4. $$1.4\times 10^{-2}$$
