My Tree and the Carbon Cycle Write a 6-8 sentence paragraph describing the role of your tree (and forests in general) in the carbon cycle. Be sure to clearly explain the roles of photosynthesis, cellular respiration, decomposition (both in the presence of oxygen and without oxygen), and combustion (assuming someone cuts down your tree and uses it for fuel, or lightning strikes it and there is a wildfire). It may be helpful to include word or symbol equations as you are discussing photosynthesis, respiration, decomposition, and combustion. Discuss human impacts on forests as they relate to the carbon cycle, specifically describing how human activities conceming your tree could impact the carbon cycle.

Consider the case of two equal but oppositely charged large conducting plates placed near each other. The plates are large enough and close enough together that fringing effects near the edges can be ignored. The diagrams below show various distributions of charge on the two plates. One is physically correct, decide which one that is. Explain your selection and include a sketch of the electric field for the correct choice. $\sigma_o$ $-\frac{1}{2}\sigma_o$ $+\frac{1}{2}\sigma_o$ $-\sigma_o$ $+\sigma_o$ (Excess charge is on outside surfaces) (Excess charge is evenly distributed on both sides) (Excess charge is on inside surfaces)

Live Demo 4: Solve a PDE using excel VBA A copper bar of length (l)=80cm, is fully insulated along its sides. It initially has a temperature distribution along its length described mathematically by equation 5.1 $U(x,0) = 100\sin(\frac{\pi x}{80})$ Equation 5.1 Both ends of the bar are placed in ice, maintaining the temperature at 0°C $U(80,t) = 0$ Equation 5.2 $U(0,t) = 0$ Equation 5.3 The temperature of the bar (U) as a function of time (t) and space (x) is given by the differential equation $\frac{\partial U}{\partial t} = 1.158 \frac{\partial^2 U}{\partial x^2}$ Using a mesh spacing of $h = 5$cm and a time step $k = 10s$, find the temperature at each grid point at time $t = 0s$, $t = 10s$ and $t = 200s$ using an explicit method.
