Question

In a movie, James Bond evades the enemy by hiding underwater for may minutes by breathing through a long, thin reed. Assuming the maximum pressure difference his lungs can handed without crushing him is 11305N/m2, what is the deepest he could go? The density of water is 1000kg/m3

Answer 1

Answer:1.152 m

Step-by-step explanation:

Given

Maximum Pressure difference his lungs can bear is 11305
`N/m^2`

We know that Pressure difference at the height h below liquid is given by

`\Delta P=\rho * g* h`

Given

`\Delta P=11305 N/m^2`

`\rho` =density of water=1000
`kg/m^3`

acceleration due to gravity
`\left ( g\right )=9.8m/s^2`

11305=
`\rho * g* h`

11305=
`1000* 9.81* h`

`h=(11305)/(9.81* 1000)=1.152 m`
