Geochemical Box Models - please use same terminology found in question Consider an element X exchanging between two geochemical reservoirs A and B. Let MA and MB be the masses of X in reservoirs A and B, respectively; let tA and tB be the residence times of X in reservoirs A and B, respectively. Further let M = MA + MB be the total mass of X in the two reservoirs combined. Consider a situation where additional mass M' is injected into reservoir A at time t=0 increasing the total amount of element X in the system from M0 to M1, with no further injection at later times; further assume that tA >> tB, that the total mass in the altered system is M1 = M0 + M', and that M0 << M'. Give an expression for MB(t) as a function of M1, tA, tB, and t. What is the characteristic time for MB to approach steady state? What is the characteristic time for MA to approach steady state?

My buddy is starting to get hypothermic (body temperature 306 K) during an epic backcountry ski adventure. Since I'm quite warm (body temperature 310 K), I decide to get in a sleeping bag with him to try and warm him up. What heat transfer mechanism will be most responsible for heating him up? For simplicity, ignore any internal temperature differences across my body (that is, assume my skin temperature is also 310 K). Use numbers to support your answer (for human skin, you can use the following values: surface area A = 1:50 m2, emissivity  = 0:970, thickness d = 0:0250 m, thermal conductivty 0:200 Jm

Project Theme 4: Insulated bar A metal bar has a cross section of A mm². The length of the bar is B m. The bar is heated from one of its ends using the heating rate of C W. Simultaneously, the other end of the bar is maintained at a constant temperature T = D°C. Determine the temperature distribution within the metal bar. The thermal conductivity of the metal bar is E [W/(m°C)]. Determine the temperature distribution using analytical calculations or computer software (Excel, Matlab). Draw a graph showing the temperature distribution as a function of distance x from the heated end of the bar According to the Fourier's Law the heat flux density [W/m²] as a function of distance equals q(x) = dT (x) dT (x) -k- Now the heat quantity Q [W] flowing through the bar becomes Q =qA = -KA- dx dx Above, Heat Supply, kW k is thermal conductivity [kW/(m°C)] A is the surface are of cross section [m²] x = 0m Area, mm² Insulation -Temperature, T(x) Heat flow Constant point at x = Bm T = D °C x

Nanotechnology, the field of building ultrasmall structures one atom at a time, has progressed in recent years. One potential application of nanotechnology is the construction of artificial cells. The simplest cells would probably mimic red blood cells, the body’s oxygen transporters. Nanocontainers, perhaps constructed of carbon, could be pumped full of oxygen and injected into a person’s bloodstream. If the person needed additional oxygen—due to a heart attack or for the purpose of space travel, for example—these containers could slowly release oxygen into the blood, allowing tissues that would otherwise die to remain alive. Suppose that the nanocontainers were cubic and had an edge length of 25 nanometers. Suppose that each nanocontainer could contain pure oxygen pressurized to a density of 85 g/L. How many grams of oxygen could be contained by each nanocontainer?

I need assistance designing three structural models on Fusion 360 (bamboo-inspired, bone-inspired, and a control cylinder) for a mechanics project. These models will be tested under compression to compare their load-bearing capacity, energy absorption, and failure modes. Here are the specific details and requirements for each design: General Requirements: External Dimensions: All models must have the same outer dimensions: height = 15 cm, diameter = 5 cm. Material Volume: Ensure each design uses approximately the same material volume (e.g., relative density = 30% of the total volume). If you have any other ideas on how to ensure the test is fair between all 3 samples please note it! File Format: Provide the designs as STL files compatible with 3D printing or a step-by-step process.  Design Specifications: 1. Control Cylinder: A simple hollow cylinder with: Wall Thickness: 2 mm. Inner Diameter: 4.6 cm (to maintain the outer diameter and wall thickness). No additional…

1. Suppose identical solid spheres are distributed through space in such a way that their centers are lie on the points of a lattice, and spheres on neighboring points just touch without overlapping. (Such an arrangement of spheres is called a close-packing arrangement.) Assuming that the spheres have unit density, show that the density of a set of close-packed spheres on each of the four structures (the "packing fraction") is: fcc: bcc: √√2/6=0.74 √√3/8=0.68 SC: π/6=0.52 √√3/16=0.34 diamond:
