Question

Please help!

A tank with a flat bottom is filled with water to a height of 4 meters. What is the pressure at any point at the bottom of the tank? (You can ignore atmospheric pressure when calculating your answer.)

A. 9.8 kPa
B. 4.0 kPa
C. 39.2 kPa
D. 18.9 kpa

Answer 1

Pressure = density*gravity*height

Answer 2

Okay but how do I find the density or gravity

Answer 3

You should know the value of gravity. And density. They are given values; not something you find.

Answer 4

gravity is 1.0 right?

Answer 5

Idk how to solve it

Answer 6

1.0 what? You need units.

What is the density of water?

What is the value of acceleration due to gravity?

Answer 7

the gravity is a constant 9.8 m/s

Answer 8

Not quite: 9.8 m/s^2

Answer 9

9.8*4=39.2

Answer 10

So it's C?

Answer 11

You never stated what density of water you're using, with units, so idk.

Answer 12

I turned it in already. 39.2 was correct
