Why does a ship made of steel float while a needle sinks?
A needle is fully metal whereas a ship is hollow so it floats
Why does the needle float when it is dropped in water parallelaly and why it sinks when dropped perpendicularly?
i think that vol of water underneath the needle when it is dropped on water parallely is more which prevents the needle from sinking.
Why does needle sinks in water?
As we know that the ratio of the density to the volume is inverse relation. As the volume of the object is lesser, than the density will be greater.So the condition of floating bodies depend upon the weight of the displaced liquid.If the object(needle) is denser,so it will not be able to displace more liquid.Therefore needle sinks in water.

Why is it that a needle may float on a clean water but sink when detergent is added to the water?
Because the detergent reduces the surface tension of the water.
Why the ship does not sink and a needle sinks?
The general principle is that an object will sink if it has a greater density than the liquid in which it is placed.
A steel needle sinks in h20 but a steel ship floats?
The needle is solid, it's density higher than water's. The ship is hollow, its overall density lower than water's.
Why do needle sinks in water but ship floats?
Whether something sinks when it's placed on water is determined by the amount (weight) of water that it displaces. The needle, being small in size and relatively high in mass (relative to its size), displaces very little water when it is placed on the surface. The weight of the needle will be more than the weight of the water that it displaces and the needle will sink. The ship, though many times heavier than the needle, will displace alot more water than the needle. The ship will float if the weight of the displaced water is more than the weight of the ship.
What is reason that a steel ship floats while a steel needle sinks?
The displaces a sufficient amount of water to keep it afloat
How does a sewing needle float on water but if you add soap it sinks?
Surface tension. Same phenomena that makes water form beads and droplets on some Surfaces acts like a skin on the water. If laid down gently, something like a needle can be carried by this skin. Soap destroys the Surface tension - one of the reasons why soap helps in getting things Clean - and the needle drops through.
Why does a niddle sink in water?
A metal needle will sink in water, because it weighs more than the water does, and since it is not buoyant, it sinks.
