Answer:
c. the volume of the part of the ship that lies below the water's surface.
Explanation:
As stated in the problem, Archimedes' Principle tells us that that buoyant force on an object is equal to the weight of fluid it displaces. The volume of water that a ship displaces is the volume it occupies below the surface.
Answer:
Work done by the frictional force is 
Explanation:
It is given that,
Mass of the car, m = 1000 kg
Initial velocity of car, u = 26.1 m/s
Finally, it comes to rest, v = 0
We have to find the work done by the frictional forces. Work done is equal to the change in kinetic energy as per work - energy theorem i.e.



W = −340605 J
or

Hence, the correct option is (a).
I think the answer should be that, Kinetic energy is contained in a moving object, while potential energy exists in a stored form.
