04: Use a surface integral to find the outward flux of F = x i + y j + z k through the surface of the sphere za. 04: Use a surface integral to find the outward flux of F = x i + y j + z k through the surface of the sphere za.
(b) (15 points) Water (species A) slowly absorbs and diffuses into a cylindrical polymer rod (species B) of length L and radius R. The rod is narrow and long enough that diffusion occurs primarily in the radial direction r over time t (diffusion in the axial direction through the two ends of the rod can be ignored). There is no reaction of water with the polymer, while the diffusion of water in the polymer can be related by the diffusion...
Oxygen diffuses from the surface of insects to the interior through tiny tubes called tracheae. An average trachea is about 2 mm long and has cross-sectional area of 2 times 10^-9 m^2. Assuming the concentration of oxygen inside is half what it is outside in the atmosphere calculate the diffusion rate J. The diffusion constant is 1.8 times 10^-5m^2/s. Express your answer to two significant figures and include the appropriate units.
56. A surface completely surrounds a +2.0 × 10-6 C charge. Find the electric flux through this surface when the surface is (a) a sphere with a radius of 0.50 m, (b) a sphere with a radius of 0.25 m, and (c) a cube with edges that are 0.25 m long. 57. A circular surface with a radius of 0.057 m is exposed to a uniforrm external electric field of magnitude 1.44 × 104 N/C. The magnitude of the electric...

"The size of spherical aerobic bacteria is limited by the rate at which oxygen diffuses through water. A bacterium with a radius greater than roughly 10 micrometers is not able to obtain enough oxygen from the surrounding water to sustain itself. Given that the diffusion constant of oxygen in water is 8 �10^-10 m^2s^-1, how long does it take oxygen in water to diffuse an RMS distance of 10 micrometers?
The electric flux through two adjacent spherical surfaces separated by a small distance is known to be the same. Mark all that may be correct. -there is no electric field present in this region of space. -there is a constant E field present in this region of space. -the electric flux through the surface of each sphere has a constant value of zero.
2. Find the flux of the vector field F = <xzyz,1> across the surface of the upper half of the sphere of radius 5, centered at the origin. Write a program that displays Welcome to Python
An electric point charge of Q = 13.1 nC is placed at the center of a sphere with a radius of r = 32.1 cm. The sphere in this question is only a mathematical surface, it is not made out of any physical material. What is the electric flux through the surface of this sphere? Tries 0/12 This same point charge is now moved out from the center of the sphere by a distance of 17.9 cm. What is the...
