Question

A research submarine has a 10-cm-diameter window that is 8.4 cm thick. The manufacturer says the window can withstand forces up to 1.2×106 N . What is the submarine's maximum safe depth in salt water?
The pressure inside the submarine is maintained at 1.0 atm .
Express your answer using two significant figures.

Answer 1

106 means 10^6 right?

Answer 2

yep

Answer 3

so pi 5^2 (8.4) (1.2)(10^6)?

Answer 4

What do u mean?

Answer 5

Amistre you gotta relate it to depth

Answer 6

20 leagues? aint good at physics much

Answer 7

Well first you must find the pressure as a function of depth. Then you find the force on the window as a function of pressure. Then substitute one into the other and you have the force on the window as a function of depth.

Answer 8

i gave u the answer earlier
