A carbonate residue is a chemical deposit left behind by the reaction of a carbonate compound with an acid, resulting in the release of carbon dioxide gas. On the other hand, an impression refers to a negative imprint or mark left behind on a surface due to pressure or contact with an object. While carbonate residues are formed through a chemical process, impressions are physical marks created by pressure or contact.
that in one you can contact but in the other its normal
The difference between bifocal and multifocal contact lenses is that biofocal contact lenses do not provide so many different angles as multifocal contact lenses do. Biofocal contact lenses do not allow the user to see as good as with multifocal contact lenses.
so as you can see when pie2 =1178 the direct contact is the same
contact tob continuous with others
There is no difference between adult contacts and regular contacts. There are two kinds of contact lenses; extended wear and disposable. There are also colored contact lenses.
contact force:when two objects are in contact with each other it is called contact force.non-contact force:when two objects are not in contact with eachover
The pressure of the plate or blanket as it comes in contact with paper.
Contact metamorphism is a type of metamorphismwhere rock minerals and texture are changed, mainly by heat, due to contact with magma.
Buoyancy is a contact force that acts on an object submerged in a fluid. It arises from the pressure difference between the top and bottom of an object.
The flow of heat between two objects in contact is determined by the temperature difference between the two objects, the thermal conductivity of the materials involved, and the surface area of contact. Heat will flow from the object with a higher temperature to the one with a lower temperature until thermal equilibrium is reached.
Contact forces and non-contact forces are both types of interactions that can cause an object to accelerate or deform. The main similarity between them is that they both involve a force acting between two objects, but the key difference is that contact forces require physical contact between the objects, while non-contact forces can act at a distance without direct contact.
