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 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 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 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.
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.

Why needle sinks down?
cause
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.
What is reason that a steel ship floats while a steel needle sinks?
The displaces a sufficient amount of water to keep it afloat
Why a 0.5g needle sinks into the sea while a ton of ice floats?
The needle sink in water because we put the needle in water...
Why a large log of wood float on water but a steel needle sink?
The water extracted by the wood log while floating is of equal weight of the wood or more. For this reason, the log of wood floats while a steel needle sinks.
Why needle sinks in water and thread does not even both has equal surface areas?
Actually, its the other way around. A needle will float on water due to surface tension of the water. Thread will not because the fibers of the thread will break the bonds of the surface tension and allow the thread to sink. Also, the thread is not straight as is the needle.
Why does a needle sink but a boat float?
The total weight of the surface area of a boat is less than than the weight of a body of water of the same size (buoyancy), so that is why it floats. A needle sinks because a body of water with the same size is lighter than the needle. Note: It is entirely possible to float a needle on water. It requires a bit of doing, but it can be done.
