C) it acts in a direction to oppose gravity. D) none of the above A completely submerged object always displaces its own A) density of fluid. B) volume of fluid. C) weight of fluid. D) all of the above E) none of the above

Explanation / Answer

1) B

2) C

3) Top

4) because water pressure is higher at bottom.

5) C

6) mass = volume * density

= (1 m^3)(1000 kg/m^3)

= 1000 kg

7) A

8) C
