2) The Mark-Houwink-Sakurada (MHS) equation allows us to relate the intrinsic viscosity, [n], of a dilute polymer solution to the polymer viscosity-averaged molar mass, M„, if one knows the constants K and "a" (M = 1 g/mol, K and "a" depend on the polymer/solvent pair and the temperature). Use the M, and [n] data from Table 2 for the following questions.

How would I draw the following graphs for a simple ohmic device from the equations V=IR and P=IV=I^2R=V^2/R: plot V vs. I with constant R, plot P vs V with constant R, plot P vs R with constant I, and plot P vs I with constant R.
Determine how many times per second each molecule moving with rms speed would move back and forth across a 6.4 mm -long room on the average, assuming it made very few collisions with other molecules.To find vx use the equation v2=v2x+v2y+v2z and the fact that molecules have no preferred direction. vrms= 473 m/s
hi, please I need answer for a,b and c.
Hi, could I get some help with this micro-macro connection physics problem involving root mean square speed? The set up is: For an atom in an ideal gas with rms speed in one direction, vx = 100 m/s, and mass m = 6.66e-27 kg, what is the temperature T in kelvin (K) to four digits of precision if Boltzman constant kB = 1.38e-23 J/K? Thank you.
