Help with this physics homework please!
Biologists think that some spiders "tune" strands of their web to give enhanced response at frequencies corresponding to those at which desirable prey might struggle. Orb spider web silk has a typical diameter of 20μm, and spider silk has a density of 1300 kg/m3.
To have a fundamental frequency at 120 Hz , to what tension must a spider adjust a 12 cm -long strand of silk?
Express your answer to two significant figures and include the appropriate units.
