1. An airplane sprinkles black soot on a snow-covered field. The soot will increase the rate that the snow melts because O soot decreases the surface area of ice crystals
O a black surface absorbs more sunlight than a white surface
O soot decreases the specific heat capacity of the snow
O soot increases the melting point of snow

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
