Aspeaker that emits sound is located at the origin of a coordinate system. two microphones are located on the x-axis, with microphone 1 at the x = 3.0 meter mark and microphone 2 at the x = 5.0 meter mark. if the speed of sound is 343 m/s, how much longer does it take a sound emitted by the speaker to reach microphone 2 than microphone 1?

What is the temperature in degrees celsius of a substance with a tempature of 49k

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.
