At what acceleration would you expect the blood pressure in the brain to drop to zero for an erect person ?why? (Assume there are no body mechanisms operating to compensate for such conditions)

Biophysics
Estimate the flux of oxygen from inside a capillary to the interior of an adjacent muscle cell. Use the estimated sizes and values from class. (just in terms of moles is enough)

please assist me to get project topic under biophysics or application of physics in medecine

Biophysics
Assume a person expends mechanical energy at a rate of 450 W. If they were 15% efficient, what would be the rate at which he/she generates waste heat energy?

Biophysics
Estimate the flow of oxygen into the cell through a side of the muscle cell squished up against the capillary. (give both moles/sec and # molecules/sec.)

Physics
A biophysics student measures her reaction time by having a friend drop a meterstick between her fingers. The meterstick falls 0.300 meters before she catches it. (a) What is her reaction time? (b) Estimate the minimum average speed of nerve impulses going from her eye to her ...

You are bending your upper body forward, while your legs remain perfectly straight and their center of gravity remains over the back of your feet (see cartoon below). What is the maximum angle  you can lean forward by without tipping over? Assume that your upper body ...

Physics
Consider the following model for the electrostatic stretching of DNA. A spring with spring constant kDNA = 250 pN/m is tethered to an immobile surface on one end and a charge of qDNA = −350e on the other. A uniform electric field of magnitude |E| = 2.5 N/C is ...
