What function represents the stress relaxation for the Kelvin-Voigt Model?

How many boundary conditions do we need to solve this?

Equations for biosolids mechanics  

Equations for biofluid mechanics Here are the Conservation of Mass and Navier Stokes Equations in cartesian coordinates:

Which of the following is the correct form of the divergence theorem related to the conservation of mass problem we are working on?  Note for cartesian coordinates,

3. Biofluid Mechanics The next 8 questions will be related to the Navier-Stokes Equations.  The problem will be pressure driven flow between parallel plates.  You will be asked to submit your written work at the end of this section.   You should start by writing the complete Navier-Stokes Equations in Cartesian coordinates on your paper.  You can also write down the continuity equation in cartesian coordinates.  You can also label the input pressure as Pin and the Output pressure as Pout, with the length of the channel (in x) = L.  The channel width (in z is >>h.

Connecting this result to fluid dynamics; consider a rectangular duct that is wide in the y direction, narrow in the z direction, and flow is only in the x direction;  which of the following statements about the flow is true ?

A random sample of 120 females results in 20 of them are cigarette smokers. A random sample of 150 males results in 26 of them are cigarette smokers. A dietician tests to determine if the proportion of female smokers is lower than the proportion of male smokers. A hypothesis test was conducted at the 5% significance level and the p-value was found to be 0.456. Which of the below is the conclusion for this test?

Suppose in a sample of 100 randomly selected people, 21 have traveled abroad. The standard error was found to be 0.041. Which of the below statements describes the 95% confidence interval?
