(a) How much work would it take to push two protons very slowly from a separation of (a typical atomic distance) to (a typical nuclear distance)? (b) If the protons are both released from rest at the closer distance in part (a), how fast are they moving when they reach their original separation?
Primary Visual Cortex (aka striate cortex aka V1 aka Area 17) Acuity: smallest visual angle of a cycle of grating; smaller visual angle = better vision Visual acuity is measured by eye doctors using distance (your distance/normal vision distance . . . 20/20) Acuity...
