Why does a solid needle placed horizontally on the surface of the water float?
Due to surface tension
If you lay a steel needle horizontally on water it will float if you place the needle vertically into the water it will sink explain why?
Needle floats if u place it on the surface of the water even its density is heavier than water because there is a thin film on the water surface that is stretched towards the sides of the container because of the collision force of the molecules & this is called suface tension when u plae the needle vertically it tears the film therefore it sinks
What will happen to a needle place in water?
It will float if placed carefully enough.
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.
Does the needle float or sink in water?
A needle sink in water.

What is a slip and score in art?
it is when u take a clay needle and make lines on the end of the clay going horizontally and vertically and then rub it with some water. You want to do this to both sides of the clay your sticking together. This way, they'll stick together and wont break! Hope that helps!=)

Why a wooden stick floats horizontally and not vertically?
because gravity pushes the stick down and since water is a non-sticking liquid (Hâ‚‚0)

How do you find which way is north with a magnet?
To find north you will need the magnet, a needle, a piece of very thin paper & a bucket of water. First you need to take the positive side of the magnet and slide it across the first half of the needle, as if you were striking a match, fifty times. Then do the same with the negative side of the magnet and the other side of the needle. Afterwards, put the needle in the paper so that there are 2 holes and the needle lies horizontally, then place in the water. The positive side of the needle will point North.
What force allows water to arrive at your house from the water treatment plant?
The hydraulic force of water allows water to be transported in the pipes. Hydraulic force from the water treatment plant is used to pump the water vertically across the underground pipes. Then, another hydraulic force pumps the water from underground to the storey that you are living in horizontally up.
What do you need to make a floating compass?
You would need a piece of cork or other soft floating material, perhaps polystyrene, also a needle and a magnet. stroke the needle with the magnet a few times in the same direction and them insert the needle into the floater so that it is horizontal when the floater is placed in water, place floater into a container of water, the needle will point toward the magnetic north.
Why can you not use electromagnetic waves in water?
Because the electric field portion of the electromagnetic wave are rapidly attenuated in water, due to its conductivity. This is also why light becomes horizontally polarized when it reflects off water, the vertically polarized part of the electric field is absorbed during the process of reflection.
Why can a carefully placed needle float on water even though it is more dense then the water?
Because of the surface tension: the attracting force between the water molecules, which effectively causes a "skin" on the top of the water. Drop a few drops of soap in the water and the needle will sink, because the soap weakens the bond between the water's molecules.
What are the forces in kayaking?
Assuming that it is moving at a constant speed. Horizontally there is the thrust from the engines/oars/whatever is pushing the boat and the drag from the water and air it is being pushed through. Vertically there is the weight of the boat and the upwards force due to the water pressure pushing on the bottom of the boat.
