When you jog, most of the food energy you burn above your basal metabolic rate (bmr) ends up as internal energy that would raise your body temperature if it were not eliminated. the evaporation of perspiration is the primary mechanism for eliminating this energy. determine the amount of water you lose to evaporation when running for 31 minutes at a rate that uses 400 kcal/h above your bmr. (that amount is often considered to be the "maximum fat-burning" energy output.)

To understand the electric potential and electric field of a point charge in three dimensions consider a positive point charge q, located at the origin of three-dimensional space. throughout this problem, use k in place of 14? ? 0. part adue to symmetry, the electric field of a point charge at the origin must point from the origin.answer in one word.part bfind e(r), the magnitude of the electric field at distance r from the point charge q.express your answer in terms of r, k, and q. part cfind v(r), the electric potential at distance rfrom the point charge q.express your answer in terms of r, k, and q part dwhich of the following is the correct relationship between the magnitude of a radial electric field and its associated electric potential ? more than one answer may be correct for the particular case of a point charge at the origin, but you should choose the correct general relationship. a)e(r)=dv(r)drb)e(r)=v(r)rc)e(r)=? dv(r)drd)e(r)=? v(r)r
