Answer:
The water pressure at the sea level is 1 atm.
Explanation:
Please find the attached graph of the relationship between pressure, p, in atms, and depth, d, in ft.
Upon looking at out given graph, we can see that pressure p (in atms) is represented on y-axis, and depth, d (in ft) is represented on x-axis.
Since d represents depth, so at the sea level depth will be 0 feet.
Now let us see our graph to find the value of y at x equals 0 or we need to find the y-intercept.
We can see that when x equals 0, the value of y is 1. Therefore, the water pressure at sea level is 1 atm.
