A bag chasing a moth emits a sequence of three chirps every 0.010 seconds and later hears the echos as shown in the diagram below. What can you infer in this situation f the bat heard echo 1 first in his left ear, then echo 2 simultaneously in both ears, and then echo 3 in his right ear? Explain your response.

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
