Answer:
Buoyancy - it is what perceive as the tendency of an object to rise when when it is submerged in a fluid it is can be defined as the ability of an object to float in the fluid .
Thrust - It is a reaction forced described quantitavely by newton third law
In general, impulse = F x time=mxv
if J is the impulse, J=<span>Ft, J=mv, and J=p because p=mv
possible formulas are
</span><span>J = Ft, J = mv and J = p</span>
To find work, you use the equation: W = Force X Distance X Cos (0 degrees)
Following the Law of Conservation of Energy, energy cannot be destroyed nor created.
So you would do 75 N x 10m x Cos (0 degrees)= 750 J
