What is the apparent weight of a submarine that weighs 1256N and it displaces 1562N of water?

Apparent weight = Fg - Fb = 1256 - 1562 = -306 N
so in this case buoyance force is greater than its real weight so it must be rising to the water surface and floats.

What is the apparent weight for a body floating in water equal to?
if its floating, its zero : weight or force = upthrust from water note: upthrust from water = weight of water displaced
Achimedes ' principle?
Archimedes principle states that any immersed body in a fluid will experience a buoyant force which is equal to the weight of fluid displaced by it and always acts upwards through the centroid of displaced volume. Note that if the object weight less than the wieght of water it displaces, it will float. If it is heavier than the weight of water it displaces, it will sink but its apparent weight in water will be its in-air weight minus the weight of the water it displaces.
What is the net force on a rock that weighs 500 N if the weight of the water it displaces is 300 N?
200 N
A toy boat weighs 12 newtons What is the weight of the water it displaces when it floats?
It displaces 12/9.8 kg of water = 1.22 Kg. This would be assuming that gravity is 9.8 M/S2
How does the shape of the boat effect it to sink or float?
The science is called "displacement". If the shape of the boat allows the amount of the boat in the water to be less weight than the water it displaces it will float. If the amount of the boat in the water weighs more than the water it displaces it will sink.
An object weighs 20 N It displaces a volume of water that weighs 15 N?
You haven't asked a question. So I'll ask one using your data, and then answer it. Q: What is the apparent weight of the object when it's completely submerged ? A: 5 N.
A mini submarine is lowered on a cable into water and displacs a volume of water which weighs 1kn if the submarine weighed 7kn before being lowered what is its apparent weight when it is fully immer?
It's 6 kN because the loss of weight equals the weight that has been displaced, i.e. 7 - 1 = 6.
What happends if the weight of an object is greather than the weight of the water?
I assume you mean "What happens if the weight of an object is greater than the weight of the water it displaces." If so, the answer is simple, it sinks. If an objects weighs less than the weight of the water it displaces, it floats.

How does a submarine work?
A submarine has tanks that are called ballast tanks. When these tanks are flooded with sea water, the submarine sinks because the sub weighs more than the water it displaces. To rise again, the sub reduces its weight by pushing compressed air into the ballast tanks. The air forces the sea water out and sub returns to the surface. It maneuvers using its rudder and planes.

Why does a helium balloon rise higher than an air balloon?
Any object surrounded by a fluid is buoyed up by a force equal to the weight of the fluid it displaces. There's an upward force on a cork in water that's equal to the weight of the water it displaces. There's an upward force on a helium balloon that's equal to the weight of the air it displaces. It so happens that a balloon full of helium weighs less than the air it displaces, so the upward force on it is greater than its weight.
