11. [-/2 Points] DETAILS OBINPHYS8 6.P.017. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A sonic depth gauge is placed 3.4 m above the ground. An ultrasound pulse sent downward reflects off snow and reaches the device 0.016 seconds after it was emitted. The air temperature is -20 C. (a) How far (in m) is the surface of the snow from the device? (Round your answer to at least three significant figures.) m (b) How deep (in m) is the snow? m Need Help? Read It 12.
