What does buoyancy depend on? the density of the surrounding air and the density of the water
atmospheric pressure and the density of the object
the density of the object and the density of the fluid
the density of the object and the force of gravity

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

it is the second option.

the answer is b, have negligible mass

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
