. Determine the pressure due to water at the bottom of a tank which is 25cm deep and is
four-fifths full of water,
(Density of water = 1000kgm',g=10ms”).​

Which would not reduce the amount of green house gasses in the air

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.

Most short-period comets do not have randomly oriented orbits because
