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 else can I help you with?
Why does needle sink when placed vertically in water but does not when placed horizontally?
When a needle is placed vertically in water, the force of gravity acting on the denser needle overcomes the buoyant force pushing it up, causing it to sink. However, when placed horizontally, the buoyant force acting on the needle is greater than its weight, allowing it to float due to surface tension and the needle's low surface area in contact with the water.
Why does a solid needle placed horizontally on the surface of the water float?
The surface tension of water creates a layer that the needle rests on, despite being denser than water. The needle's weight is dispersed over a large enough area that it balances the upward force of surface tension. This allows the needle to remain afloat on the water's surface.
What makes a needle to float in water?
A needle can float on water due to surface tension. When the needle is carefully placed on the surface of the water, its weight is not enough to break the surface tension created by the water molecules, causing it to float.
What will happen to a needle place in water?
A needle placed in water will float due to surface tension. The surface tension of water allows the needle to be supported on the surface rather than sink.
Does needle float on water?
Yes, a needle can float on water if it is carefully placed on the surface due to surface tension. However, if the needle is pushed down into the water, it will sink due to its density being greater than that of water.

Why the rota-meter is vertically upward not horizontally in the experiments?
The float in rotameter is lifted by the liquid. Rotameter is calibrated for particular liquid or gas with its exact density. if we mount it horizontally float will not come to its original place.
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.
What liquids can a needle float on?
A needle can be made to float on very still water.
Can you float a needle?
Yes, you can float a needle I have done it before. It doesn't have to do with density though it has to do with surface tension.

Why gas come from carburetor after you shut down?
The problem is most likely in the float bowl. The float could be bad. The likely cause is the needle valve that is control by the float is stuck, or dirt has gotten between the needle and needle seat. This is an easy fix. Carefully remove the float bowl. The float will be held in place by a pin. Remove the pin, and float. Check that there is no fuel in the float, and that it floats in gas, if not replace. The needle valve will come out with the float, as they are connected by a wire link. Make sure needle vale is clean, and able to move freely inside it's housing. Check the bottom of the housing at the needle seat to make sure it is clean of dirt. Reassemble, and you should be ready to go.
How do you clean float needle on 16.5 HP Briggs and Stratton Engine?
To clean the float needle on a 16.5 HP Briggs and Stratton engine, first, remove the carburetor from the engine. Disassemble the carburetor to access the float and needle assembly, then carefully remove the float and needle. Clean the needle and seat with carburetor cleaner and a soft brush to remove any debris or varnish. Reassemble the components and reinstall the carburetor, ensuring all connections are secure.
Why does 302 2 barrel engine diesel?
I would suspect a bad needle valve and seat in the carburetor. The float level can also be set too high. I would replace the needle valve and seat and check float level.I would suspect a bad needle valve and seat in the carburetor. The float level can also be set too high. I would replace the needle valve and seat and check float level.
Where is the carburetor needle valve?
It is in the float chamber of the carburetor.
What will happen to a needle place in water?
A needle placed in water will float due to surface tension. The surface tension of water allows the needle to be supported on the surface rather than sink.
