The speed of sound through ocean water is nearly always _______________.
AI Explanation
The correct answer is C) faster than the speed of calibration for the fathometer.
The speed of sound through ocean water is generally faster than the speed of calibration for the fathometer, which is typically around 1,500 meters per second. This is because the speed of sound in water is influenced by factors such as temperature, salinity, and depth, and can vary between 1,450 to 1,550 meters per second, with the higher end of the range being more common.
The other options are incorrect because option A) is not always true, as the speed of sound can be faster than the fathometer calibration speed even in warm water, option B) is incorrect as the speeds are not the same, and option D) is incorrect as the speed of sound is generally faster, not slower, than the fathometer calibration speed.
