Yes.
No,it is balanced forces
Coplanar forces are a set of forces all of which act in the same plane. Non-coplanar forces are a set of forces in which at least one act in a direction incline to the plane formed by two of the forces.
the principle that resultant of the external forces and kinetic reaction acting forces is zero
Three. Equal forces, two.
Probably the movement on a swing can be approximated by assuming that the magnitude of each swing will be a certain percentage of the previous swing (because of lost energy).
Yes, water beads up on wax paper because its cohesive forces are greater than the adhesive forces.
Water has stronger adhesive forces than adhesive forses. Mercury on the other hand has stronger cohesive forces than adhesive. cohesive forces hold molecules of the same substance together , vice-versa for adhesive forces
If the shape of the meniscus is concave up then the cohesive forces are weaker than the adhesive forces. If the shape of the menicus is concave down then the adhesive forces are weaker than the cohesive forces. So capillary rise is where adhesive forces are stronger.
cohesive force and Adhesive force
yes, as the molecular force is attractive at larger distance apart in case of similar molecules rather than dissimilar molecules. Kamal panda_kamal@rediff.com
Cohesive forces in given case are greater than adhesive forces. So water molecules form spherical shape. This behavior is more prominent in mercury.
Water has both cohesive and adhesive forces. They are similar.The cohesive of water describes how the molecules of water are attracted to one another. We observe the cohesive forces of water when we see a drop of water sitting on a surface. The water does not spread because the molecules are attracted to one another. Surface tension of water is due to its cohesive properties.The cohesive forces of water are due to hydrogen bonding between molecules.Adhesive properties of water are how the molecules are attracted to other substances. We observe the adhesive forces of water when we see the edge of water in a glass is attracted up on the sides of the glass. This is most apparent when the diameter of the glass vessel is less than a centimetre. It is called a meniscus. Trees use this adhesive property of water to help suck water up from the ground. If the diameter of the glass is small enough, as in a glass capillary, the water will rise up the tube by itself due to adhesive forces.
Surface tension; Capillary action; and Turgor Pressure.
Meniscus is not composed of anything its a physical properties due to surface tension of liquids. It is dependant on the: cohesive forces - binds similar molecules together. adhesive forces - bind a substance to a surface. Water for example in a glass tube the meniscus is U-shaped, we say, that the adhesive forces between the water and glass are greater, than the cohesive forces between water molecule, but for mercury, the meniscus is curved downward therefore we would say ..... One other thing in narrow tubes the rise of liquids is called capillary action.
it helps clean dust and provides the cleanes and pupliters in the cloth time warmere it is .
I think you mean 'capillarity' which happens in very thin tubes because the adhesive forces between water and glass molecules is greater than the cohesive force between water molecules alone. In narrow tubes, this is enough to pull the liquid up the tube.
The liquid rises up due to the forces of adhesion between the capillary and liquid.. It rises till the extent when adhesive and cohesive forces and external forces balance each other...
