Question

The amount of water pressure exerted on a scuba diver varies with depth. The graph below shows the relationship between pressure, p, in atmospheres, and depth, d, in ft.

Depth of Water and Water Pressure
A graph entitled Depth of Water and water pressure has depth on the x-axis and pressure on the y-axis. A line with positive slope goes through (0, 1) and (32, 2).
Based on the information in the graph, what is the water pressure at sea level?
StartFraction 1 Over 32 EndFraction atm
One-fourth atm
0 atm
1 atm

Answer 1

D: 1 atm.

Explanation:

Answer 2

D. 1 atm

Explanation:

We have been given a graph that shows the relationship between pressure, p, in atms, and depth, d, in ft.

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.

We can see that at x equals 0, y is at 1. Therefore, the water pressure at sea level is 1 atm and option D is the correct choice.
