A sailor sends a sonar pulse to find out the depth of the ocean. If it takes 0.8 seconds from the time the pulse is sent until the echo is heard, how deep is the ocean here? (Sound travels at 1500 m/s in water; remember to account for the round trip.)

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.
