i am doing this experiment to find the surface tension. as i am using silicone oil and water. the needle is dipped in the water and produced silicone bubble and took images. i found the angle but i don't know which equation to use. please if anyone can help me out with the equation. thanks

What are the characteristic that make sponge more important for domestic?
Holes inside the fabric retain water via surface tension
What makes water have surface tension?
Surface tension is The attraction of molecules to each other on a liquid's surface? Surface tension of water is the physical property of hydrogen bonding that makes the water molecule. The way that this works is that a water molecule (H2O) is a polar molecule. This is because the oxygen has a much higher electronegative value than the hydrogen. This means that the oxygen gets a lot higher 'share' of the shared electrons than the hydrogen does. This gives oxygen a very high partialnegative charge, and the hydrogen a very high partial positive charge. Because of these high partial charges on each end of the molecule, they are very highly attracted to each other
What material is melted to provide magma to the cascade mountains?
Magma is semi-molten rock heated by the earth's core.
Where do receptor molecules end up after receptor-mediated endocytosis?
Its NOT 'on the inside surface of the cell membrane' Probably ' on the inside surface of the vesicle'
What forces inside earth shape earth's surface?
Heat deep inside Earth is constantly reshaping the planet's surface.
Why is surface tension helpful to some oragisms?
Many insects and microscopic organisms need to be in direct contact with the air to feed, live, and reproduce. The surface tension on water allows many insects to "walk" across the surface making the capture of prey much easier. During the hatching cycle, many insects larvae come to the surface of the water, using the surface tension for support while releasing the larvae inside.

What is vaporization that occurs on the surface of a liquid?
That would be evaporation; the particles inside the liquid escape from the surface and into the atmosphere/air.
The sustance that reduces surface tensin in the alveoli is?
Surfactant is a substance which lines the inside of alveoli. It is composed of a phospholipid bilayer, which have hydrophyllic and hydrophobic properties. This allows it to reduce surface tension.
What is the water tension?
Cohesive forces between liquid molecules on the surface cause a phenomenon known as surface tension. Due to the lack of surrounding molecules, surface molecules adhere more strongly to another than they would inside a liquid. Surface tension is measured in newtons per meter (N/m) or dyne per centimeter (dyn/cm). The formula to figure surface tension is gamma equals the ratio of the surface force to the distance along which the force acts or gamma = F / d. Variables such as temperature and solution purity can cause F to vary. Pure water at 20 degrees (C) has a surface tension of 72.8 dynes/cm.
Why does water have a meniscus if you put it inside a graduated cylinder?
It is a problem of surface tension of water and contact angle between water and glass (or a plastic).
How do soap bubbles become round?
A sphere is the shape that has the largest volume and smallest surface area. the surface tension pulls the surface of the bubble in but the volume of air inside the bubble remains constant so the bubble wants to become a sphere.
Can bubbles be square?
The bubbles can never be of square shape for surface tension reasons as well as the reason that the pressure inside the bubble is distributed equally through all directions.

What red fluid could be dripping on my right ankle inside my car as I drive?
Automatic Transmission Fluid

How does soap bubble?
adding soap to water weakens the pull of the surface tension, and makes the surface of the water much stretchier. It spreads out enough for you to blow air inside- it's ability like blowing balloons up with water-thanks for reading loolx
