Amotorboat traveling 4 m/s, east encounters a current traveling 3.0 m/s, north. a) what is the resultant velocity of the motorboat? b) if the width of the river is 80 meters wide, then how much time does it take the boat to travel shore to shore? c) what distance downstream does the boat reach the opposite shore?

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.

When measuring volume, why is it important to use the correct tools and units to attain the greatest accuracy? use specific examples from the lab to support your answer. (5 points)
