Why The Free Surface Of Water Is Concave? When liquid water is confined in a tube, its surface (meniscus) has a concave shape because water wets the surface and creeps up the side. Mercury does not wet glass – the cohesive forces within the drops are stronger than the adhesive forces between the drops and
What Happens When Light Strikes A Concave Lens? A concave lens causes parallel light rays to spread out. The focal point is the point at which parallel light rays meet after being reflected or refracted. Distort means to change the shape of something by twisting or moving the parts around. A convex lens forms an
Why Does The Production Possibilities Frontier Curve? Why Is the PPF Often Curved Instead of Straight? The curved shape reflects the law of diminishing returns. This law states that there comes a point where an added production factor has less of an impact. For example, adding additional resources toward the production process may initially result
Which Is Thick In The Middle And Thin At The Edges? A convex lens can be defined as the lens which are thicker at the center and thinner at the edges whereas the concave lens can be defined as the lens which are thicker at the edges and thinner at the center. Convex lens is
What Would Cause The Production Possibilities Frontier To Be Bowed Outward? The production possibilities curve is bowed in shape because of the law of increasing opportunity cost, which explains the idea that the more units of a product are produced, the less capability the economy has of producing other products. What causes a PPF to
Is Concave Or Convex Better? Concave is better if you press and drag the analog sticks to move them. Convex is better if you push the analog sticks with your thumb to move them. What’s better concave or domed? You’ll be quick to move and ready to quickly aim. For defensive players, like rifle or
In Which Case Magnification Is Less Than 1? In a concave mirror, when the distance of the object is less than the focal length, the magnification will be greater than one. When the distance of the object is greater than the focal length, then the magnification is less than one. Which mirror magnification is always
Is Our Eye Concave? Some lenses converge the light rays whereas some diverge the light rays. The light entering our eyes must be converged at a single point. Therefore, the lens in our eyes must be a converging lens and a convex lens is a converging lens. Therefore, the lens present in a human eye
What Does The Slope Of The PPF Show? The PPF captures the concepts of scarcity, choice, and tradeoffs. … The slope of the PPF indicates the opportunity cost of producing one good versus the other good, and the opportunity cost can be compared to the opportunity costs of another producer to determine comparative advantage. What
What Is The Concave Rule? The concave-convex rule states that if a concave surface moves on a convex surface, roll and slide must occur in the same direction, and if a convex surface moves on a concave surface, roll and slide occurs in opposite directions. Who proposed concave-convex rule? Note the shift of axis of
