I'm trying to find the resistivity of conducting putty at room temperature and I've been looking all over google with no success. There isn't really anything more I can do to work it out so I'm wondering if anyone here knows. Thanks :)

Homework Statement We did an experiment using resistance putty and a multimeter. We changed the radius of the putty but kept the length the same. We recorded the resistances at different radius'. I know that physics theory says that resistance is inversely proportional to cross-sectional...

So, the slope is 1.5129, does that mean k is 1.5129 or is it (4pi^2)/1.5129 = k? thanks :)

Hi guys! I'd really like help with this as I'm stuck. Homework Statement Investigate the mathmatical relationship between period of a spring and mass. Finding the spring constant (k) from measuring periods with a spring and different hanging masses. Homework Equations T = 2pi...
