Air at 100 c flows across a thin, flat plate of subliming naphthalene that is 3.4 m long. the reynolds number at the trailing edge of the plate is at the upper limit for a laminar boundary layer (re 5e5). estimate: (a) the average rate of sublimation in kmol/s*m2; and (b) the local rate of sublimation 0.5 m from the leading edge. vapor pressure of naphthalene = 10 torr viscosity of air 0.0215 cp; molar density of air 0.0490 kmol/m3; and diffusivity of naphthalene in air = 0.94x10-5 m2/s

Select the correct answer from each drop-down menu.describe what happens to a carbon-11 atom when it undergoes positron emission.the decay of a carbon-11 atom _1_, and this causes it to emit _2_.options for 1: > changes a neutron into a proton> changes a proton into a neutron> is hit with a neutron> reconfigures its protons and neutronsoptions for 2: > a negatively charged electron-sized particle> a positively charged election-sized particle> two atoms and several neutrons> two neutrons and two protons
