What else can I help you with?
True or false forces aways act alone?
No,it is balanced forces
What is the definition of coplanar and non coplanar 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.
What is d'alembert's principle?
the principle that resultant of the external forces and kinetic reaction acting forces is zero
What is the minimum number of unequal forces whose vector sum can equal zero?
Three. Equal forces, two.
What are the conditions for coplanar parallel forces?
Coplanar parallel forces are forces that lie in the same plane and have the same line of action but different points of application. The conditions for coplanar parallel forces are that they must have the same direction, be non-collinear (not acting along the same line), and have magnitudes that are proportional to their distances from a common point. These forces create a system in which the net force is equal to the vector sum of all the individual forces.
Water beads up on wax paper because its cohesive forces are greater than the adhesive forces?
Yes, water beads up on wax paper because its cohesive forces are greater than the adhesive forces.
What is the difference between adhesive and cohesive forces in materials?
Adhesive forces are the attraction between different substances, while cohesive forces are the attraction between molecules of the same substance.
What is the difference between cohesive and adhesive forces in materials?
Cohesive forces are the attraction between molecules of the same substance, while adhesive forces are the attraction between molecules of different substances. In materials, cohesive forces hold the molecules of the material together, while adhesive forces allow the material to stick to other surfaces.
Capillary rise is due to the action of adhesion . is it right or wrong?
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.
What are some forces that can act when in contact?
cohesive force and Adhesive force
Are cohesive forces greater than adhesive forces?
It depends on the material. In some materials, cohesive forces (forces between molecules of the same substance) are stronger than adhesive forces (forces between molecules of different substances), while in others, the opposite is true. Generally, cohesive forces tend to be stronger in materials with similar molecules, such as water.
Is the interaction between wax paper and water cohesive or adhesive?
The interaction between wax paper and water is adhesive. Adhesive forces are when two different substances stick together, whereas cohesive forces are when the same substance sticks together. In this case, the water molecules are attracted to the wax paper, causing them to adhere to each other.
Why is water rise in capillary tube wheras mercury falls in capillary tube?
This happens due to the difference in adhesive and cohesive forces. Water molecules are more attracted to the walls of the tube (adhesive forces) than to each other (cohesive forces), causing water to rise. Mercury has stronger cohesive forces compared to adhesive forces, so mercury is more attracted to itself than to the walls of the tube, causing it to be depressed or fall in the capillary tube.
Why does meniscus of mercury curve in opposite directions?
The meniscus of mercury curves in opposite directions depending on the container it is in due to the difference in adhesive and cohesive forces. In a glass container, adhesive forces dominate causing a concave meniscus, while in a steel container, cohesive forces dominate causing a convex meniscus. The direction of the curvature is determined by the balance of these forces.
Why does water wet glass and mercury does not?
Water wets glass because the force of adhesion between the glass molecules and water molecules is greater than the force of cohesion between the water molecules and glass molecules. Mercury does not wet glass because the force of cohesion is greater than the force of adhesion
2 How can you explain Cohesion and adhesion in term of water molecules?
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.
What special abilities do water molecules have because they are polar?
Water molecules have special abilities due to being polar that include cohesive forces, where water molecules are attracted to each other, allowing water to form droplets; adhesive forces, where water molecules are attracted to other substances; and high surface tension, allowing some insects to walk on water.
