Answer:

Explanation:
The buoyant force F is equal to the weight of the displaced fluid. The weight of the displaced fluid is
, where
is the mass of the displaced fluid. The mass of the displaced fluid is
, where
is the density of the fluid and
is the displaced volume, which is equal to the submerged volume of the cilinder
.
Putting all together we have:

Answer:
Explanation:
work done=force*displacement
=350N*15m
=5250 joule
A liquid is a matter that neither has a fixed shape but fixed volume...in college really need to know this.
GOOD LUCK
