PLEASE HELP ASAP Joe, a hiker, stands at the top of a hill on a trail above the ocean. Joe's friend Dave is just starting out at the
trailhead, which is at the beach.
Which statement about this scenario is accurate?
O The air Joe is breathing is denser than the air at sea level.
O The air pressure is higher where Joe is than where Dave is.
O If Joe keeps going up, air pressure will continue to decrease,
O The air Joe is breathing is denser than the air Dave is breathing,

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.
