1. George V Const in Antarctica is the windiest place on Earth, Wind speeds there can reach 3.00 x 10° km/h. If a research plane flies against the wind with a speed
6f4.50 107 km/h relative to the wind, how long does it take the plane to fly
between two research stations that are 250 km apart?

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.

The mantle is made up of which structural zones?

As the ball rolls down the ramp, there are changes in kinetic and potential energy. how much kinetic energy does the ball have when it reaches point b? a) 0j b) 25j c) 50j d) 100
