Calculating conductivity of the cell interior and the blood

AI Thread Summary
To calculate the conductivity of the cell interior and blood, one must understand the relationship between ion concentration and conductivity. Conductivity can be determined using the formula that incorporates the concentration of ions and their charge. The provided concentrations for K+, Na+, and Cl- in both the cell and blood serve as the basis for these calculations. It is essential to show any preliminary work or calculations attempted to receive further assistance. Completing these calculations is crucial, as the assignment is due tomorrow.

They give me a table of ion concentrations of the most common ions in the cell interior and in the blood. I am asked to calculate the conductivity of the cell interior and that of the blood. I have no idea how to calculate conductivity if I only know the concentrations. Here is the table I am provided with

Ion, Ion concentration in cell, Blood
K+, 140, 4
Na+, 10, 145
CL- , 5, 116


Any help would be appreciated ASAP. This assignment is due tomorrow so I would really appreciate any advice!

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
