Final answer:
To calculate the total pressure on a submarine window 3 km below the ocean surface, the pressure due to the ocean depth and the internal pressure of the submarine must be summed. The average density of seawater is needed to find the pressure due to the depth using the formula P = ρgh, and then the atmospheric pressure (1 atm) is added. The pressure can then be used to calculate the force on the window.
Step-by-step explanation:
The question involves calculating the total pressure exerted on a window of a submarine that is submerged 3 km below the ocean's surface. To find the pressure on the submarine window, we must consider both the pressure of the water at that depth and the internal pressure of the submarine. The pressure exerted by a liquid column at a given depth can be calculated using the formula P = ρgh, where ρ is the density of the liquid, g is the acceleration due to gravity, and h is the height of the liquid column.
To calculate the total pressure, we add the atmospheric pressure inside the submarine, 1 atm, to the pressure due to the depth. The pressure due to the depth can be converted to atm by dividing the result by the standard atmospheric pressure in pascals (101325 Pa), since 1 atm = 101325 Pa. Once we determine the total pressure in atm, we can convert it to pascals and then use the formula for force (F = PA, where P is the pressure and A is the area of the window) to find the force on the window. However, the average density of seawater is missing in the question, so we cannot calculate the pressure without it.
