Question

question 6 of 20 : select the best answer for the question. 6. pressure and depth share a linear relationship. for every ______ meters that the depth of seawater increases, the pressure increases by another atmosphere or bar. a. 25 b. 10 c. 1000 d. 100

Explanation:

In the context of seawater pressure and depth, the relationship is such that for every 10 meters increase in depth, the pressure increases by approximately one atmosphere (or bar). This is a known concept in the study of fluid pressure, particularly in oceanography (a subfield of Natural Science, specifically related to Physics and Geography in terms of fluid dynamics and earth's water bodies).

Answer:

D. 100 (Wait, no, correction: The correct answer is actually D? No, wait, the standard is that for every 10 meters of seawater depth increase, pressure increases by about 1 bar/atmosphere? Wait, no, let's recall: The pressure at the surface of the ocean is 1 atmosphere. For every 10 meters you go down, the pressure increases by approximately 1 atmosphere (or 1 bar, since 1 bar is approximately equal to 1 atmosphere in this context). Wait, but the options: A.25, B.10, C.1000, D.100. Wait, maybe I made a mistake. Wait, actually, the correct value is that for every 10 meters of depth in seawater, the pressure increases by about 1 bar (or atmosphere). So the correct option should be B. 10? Wait, no, let's check again. Wait, the pressure in seawater: the hydrostatic pressure formula is \( P =
ho gh \), where \(
ho \) is the density of seawater (about 1025 kg/m³), \( g \) is 9.8 m/s², and \( h \) is depth. Let's calculate the pressure at h = 10 m: \( P = 1025 \times 9.8 \times 10 = 100450 \) Pa, which is approximately 1 bar (since 1 bar = 100000 Pa). So yes, for every 10 meters depth increase, pressure increases by about 1 bar. So the correct option is B. 10? Wait, but the original thought was wrong. Wait, the options: B is 10. So the correct answer is B. 10.
