Sanity Check 5. If the tension (i. e., force) on a string increases 2 times but the density of the string remains
constant, the new speed of waves on the string will be how many times greater than the
original speed?

L

Why does the input force have to be greater than the force needed to lift the bale?

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.
