Question
A submarine emits a SONAR pulse which return from an under water cliff in 1.05 second. If speed of sound in salt water is 1531 m/sec. How far away is the cliff.Select an answerA803.7 mB765.5 mC1568 mD1607.4 m
Solution
To solve this problem, we need to use the formula for distance which is speed multiplied by time. However, since the sound has to travel to the cliff and back, the time is divided by 2.
Step 1: Divide the total time by 2 to get the time it takes for the sound to reach the cliff. 1.05 sec / 2 = 0.525 sec
Step 2: Multiply this time by the speed of sound in salt water to get the distance. 0.525 sec * 1531 m/sec = 803.475 m
So, the cliff is approximately 803.7 meters away. Therefore, the answer is A803.7 m.
