Hair growth We consider a liquid (of density $p$) which wets a vertical surface located at $x = 0$ as in Figure 1. We speak of capillary rise. The objective is to determine the law linking the maximum height $h$ to the wetting angle $\theta$. air $R(s)$ $P_{atm}$ $\theta$ $ds = \sqrt{dx^2 + dz^2}$ liquid $x$ FIGURE 1 - Diagram of capillary rise. 1. The interface being curved, show that the pressure in the liquid at a point on the rib interface $z$ is written $P_L(z) = P_{atm} - \frac{\gamma}{R}$ (6) where $P_{atm}$ is the pressure in the air (assumed constant), $\gamma$ the surface tension and $R$ the radius of curvature of the interface at this point [in the ($x$, $z$) plane). 2. Write another equation for the pressure at this point (law of hydrostatics). 3. Show using the notations in Figure 1 that $ds = R \frac{dz}{sin \phi}$ (7) 4 By integrating $z$ between 0 and $h$ in the pressure equation, deduce that $h(\theta) = \ell_c \sqrt{2(1 - sin \theta)}$ (8) where we will express the capillary length $\ell_c$ as a function of the parameters $\gamma$, $p$ and the gravitational constant $g$. 5. Estimate its value for water. Comment. Radius of gyration We define the radius of gyration $R_g$ of a polymer of N monomers (N + 1 balls at positions $r_i$, connected by N links of length $a$) according to $R_g^2 = \frac{1}{N+1} \sum_{i=1}^{N+1} (r_i - r_{0})^2$ (9) where $r_0r$ is the barycenter.

"Ferns" include many plants that have vascular tissue but not seeds. Ferns first arose 360 million years ago and many species are still alive today. "Angiosperms" include plants with seeds and flowers. Angiosperms arose about 275 million years ago and many species are still around today. A group of scientists found a large rock that had been displaced from the earth recently. They found it came from a layer of rock that was 200 million year old. What is true about the fossils they might find in this layer of rock? Pick the single best answer. They would not find ferns or angiosperms. They would find both ferns and angiosperm They would find ferns but not angiosperms They would find angiosperms, but not ferns.

flow for this year is calculated as follows: Revenues: 800 COGS (other than depreciation): 400 COGS (depreciation component): 80 SGA (other than depreciation): 100 SGA (depreciation component): 40 Capital Expenditure: 60 Asset Sales (After-Tax): 25 Increase in Net Working Capital: 20 The firm's tax rate is 45%. a) To calculate the project's free cash flow for this year without depreciation, we need to exclude the COGS (depreciation component) and SGA (depreciation component) from the calculations. Free Cash Flow = Revenues - COGS (other than depreciation) - SGA (other than depreciation) - Capital Expenditure - Asset Sales (After-Tax) - Increase in Net Working Capital Free Cash Flow = 800 - 400 - 100 - 60 - 25 - 20 b) The actual depreciation tax savings can be calculated using the formula: Depreciation Tax Savings = (Tax Rate) x (Depreciation) In this case, the depreciation tax savings would be: Depreciation Tax Savings = (0.45) x (80) The actual free cash flow for this year is calculated by subtracting the depreciation tax savings from the free cash flow calculated in part a.
