This question is about Hohmann transfer orbits. One possible method to terraform the planet Mars is to increase it's water content. This could be achieved by changing the orbits of icy asteroids in the asteroid belt so that they hit Mars and deliver their water to the planet. (a) Assuming an initially circular orbit for an asteroid with an orbital radius of 2.52A.U. and a circular orbit for Mars of 1.52A.U., calculate the du required for the asteroid to be moved onto a transfer orbit that will bring it to the orbit of Mars. You may find it useful to follow the following steps. (i) Determine the initial orbital velocity of the asteroid. (ii) Determine the eccentricity of the transfer orbit between the two circular or- bits. (iii) Determine the velocity of the transfer orbit at perigee. (iv) Determine the velocity of the transfer orbit at apogee. (v) Determine the change in velocity required to move from a circular orbit to be at apogee for the asteroid.
What do differential and integral analyses of kinetic data entail? Which is more precise and why?
Develop a mathematical expression for the effective mass transfer rate achieved by an implanted drug delivery device that consists of a spherical core of radius R0 containing the drug, surrounded by a gel barrier of uniform thickness (R1-R0), i.e., the radius of the device (reservoir + barrier) is R1. When implanted, a scar tissue layer of thickness (R2-R1) forms around the device. State and justify any assumptions you might make. For a spherical shell, the flux and mass transfer rate are given by the following expressions (see notes “Steady State Molecular Diffusion: Geometry Effects”
