Answer:
The seismic refraction is a geophysical principle governed by Snell's Law. Used in fields of engineering geology geotechnical engineering and exploration geophysics, seismic refraction traverses are performed using a seismograph or geophone in an array and an energy source
Answer:
1.24 m/s
Explanation:
Metric unit conversion:
9.25 mm = 0.00925 m
5 mm = 0.005 m
The volume rate that flow through the single pipe is
This volume rate should be constant and divided into the 4 narrower pipes, each of them would have a volume rate of
So the flow speed of each of the narrower pipe is:
