Ethan dives 10 meters into the atlantic ocean. how much pressure does he experience?
a. 1 atm
b. 10 atm
c. 35 ppt
d. 29.4 psi

The answer is A. 1 atm.

Solution:

Pressure in terms of height can be calculated using the formula:

P = pgh

where: p = density (kg/m^3); g = gravitational constant (m/s^2); h = height (m)

Using SI units: P = 1000(kg/m^3)*9.81(m/s^2)*10(m) = 98,100 Pascals

Convert Pascals to atm:

98,100 Pa (1 atm/101325 Pa) = 0.968 atm = rounded up to 1 atm
