Two guitars are playing together producing a beat frequency. the first guitar is playing at a frequency of 867 hz and the beat is produced every 0.04 seconds. what are some possible frequencies the other guitar could be playing to make this beat? (1 point)
875 hz or 860 hz
904 hz or 830 hz
878 hz or 856 hz
892 hz or 842 hz

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.
