The wind chill, which is experienced on a cold, windyday, is related to increased heat transfer from exposedhuman skin to the surrounding atmosphere. Consider alayer of fatty tissue that is 3 mm thick and whose inte-rior surface is maintained at a temperature of 36C. Ona calm day the convection heat transfer coefficient atthe outer surface is 25 W/m2K, but with 30 km/hwinds it reaches 65 W/m2K. In both cases the ambientair temperature is 15C.(a) What is the ratio of the heat loss per unit area fromthe skin for the calm day to that for the windy day

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.
