Consider a bacillus of radius r0 within which respiration
occurs at a uniform volumetric velocity. See image below. The
oxygen consumption inside it (species A) is governed by a
homogeneous chemical reaction of order one.
(a) If a molar concentration of CA (r0) = CA0 is maintained on
the surface of the organism, obtain an expression for the radial
distribution of oxygen, CA (r), within the organism.
(b) Obtain an expression for the rate of consumption of NA
oxygen within the body.
Assume:
- There is no flow along the cylinder axis
- The system is subject to stationary conditions

A small solid sphere of mass M0, of radius
R0, and of uniform density ρ0 is placed in a
large bowl containing water. It floats and the level of the water
in the dish is L. Given the information below, determine the
possible effects on the water level L, (R-Rises, F-Falls,
U-Unchanged), when that sphere is replaced by a new solid sphere of
uniform density.

A uniform electric field is directed out of the page within a
circular region of radius R = 2.50 cm. The magnitude of the
electric field is given by E = (3.50 × 10-3 V/m•s)t, where t is in
seconds. What is the magnitude of the magnetic field that is
induced at radial distances (a)1.50 cm and (b)6.50 cm?

Consider a wire of uniform density and mass M shaped into a
quarter circle of radius R.The wire is located in the xy plane,
with the origin at the focus of the quarter circle (i.e at the
center of the circle of which the wire is part). Choose the x axis
parallel to the line that connects the endpoints of the wire, so
that the y-z plane is a plane of reflection symmetry for the wire.
This means that the...

Consider a continuous culture of Bacillus subtilis
bacteria, which are used to produce the enzyme amylase during the
growth phase. The relevant parameters for growth of this bacteria
are μMAX = 0.88 hr-1, YX/S = 0.5
gdw/gr substrate, S0 = 4.0 gr substrate/L, and the Monod
constant KS = 0.3 gr/L, while the protein yield during
growth phase is YP/X (aka product parameter α) = 0.12 g
