Does the needle float or sink in water?
A needle sink in water.
How does a needle float on water?
the way it float is surface tension!!
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.
What will happen to a needle place in water?

Explain why a swing needle can float on the surface of water in a glass?
Due to surface tension, the upper surface of water acts like a stretched membrane which enables it to float a swing needle.

Surface tension
Why can a sewing needle can float on the surface water in a glass?
Yes if the surface tension of the water is not broken. If you are careful you can place a needle on the surface of the water in a glass. Also if you reduce the surface tension with detergent (just a very little is enough) the needle will sink because it's density is greater than that of the water. NO (if the surface tension of the water is broken, a needle cannot float on the surface of water. This is because the needle has higher density than water (density is mass divided by volume).
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 tomato float in water?
It has air inside that makes it float.
