What is called covalent bond? Covalent bond, in chemistry, the interatomic linkage that results from the sharing of an electron pair between two atoms. The binding arises from the electrostatic attraction of their nuclei for the same electrons. Where is the covalent bond in DNA? The DNA double helix has two types of bonds, covalent […]

What are the 6 classifications of sediment sizes? Sand and silt may be further modified by the terms (very) coarse, medium, and […]

Why is elbow so important? In conjunction with the shoulder joint and wrist, the elbow gives the arm much of its versatility, as well as structure and durability.

What is Stokes law and its derivation? The law is derived considering the forces acting on a particular particle as it sinks through the liquid column under the influence of gravity. The force that retards a sphere moving through a viscous fluid is directly proportional to the velocity and the radius of the sphere, and […]

Why are the mirror fitted on the outside of cars convex? Convex mirrors have the ability to cover wider field of view by forming diminished and virtual image of the objects. Thus, the mirrors fitted on the outside of cars are convex so that larger view of the road can be observed by the driver […]

How many whooping cranes are left today? We appreciate your contribution to the recovery of the Whooping Crane Eastern Migratory Population. This report is produced by the International Crane Foundation. The current estimated population size is 80 (39 F, 38 M, 3 U). Seventeen of these 80 individuals are wild-hatched and the rest are captive-reared. […]

What force acts on the marble to slow it to a stop? Friction What was the force that was acting on the marble? A “push” centripetal force acted on the marble: this force, supplied by the bottom of the cup, kept the marble going in a circular path and not flying away in a straight […]

What is the focal point of an artwork? The focal point of a painting is the area in the composition to which the viewer’s eye is naturally drawn. It is essential to classic art, although abstract artists may deliberately create compositions without focal points. Focal points may be of any shape, size or color. Is […]

What is the difference between a conceptual framework and a conceptual model? Framework indicates the components, dimensions, and directions of the study prior to methodological approach of the researcher, while Model is a theoritical concepts that underscore the dimensions and components of empirical investigations. What is conceptual framework example? A conceptual framework is an analytical […]
