On a laterally convex slope, water disperses as it flows downslope, and erosion rates will generally be less than for a uniform slope case. MRT determines the shape of the curve. PPC is concave to the origin. That is, as we move down along the PPC, the opportunity cost increases. To explain the concavity of PPC we have to understand the meaning of opportunity cost and marginal opportunity cost too. If the society is able to increase the resources due to the process of growth, new curve GH is formed. These points are generally not local maxima or minima but stationary points. 2. If the graph is concave (curved upward), the slope is increasing. For example, if we increase the production of wheat, from 3000 units to 6000 units, then we lose 3000 (12000 – 9000) of guns. The shape of transformation curve is changed by. The decrease in hydraulic conductivity with decreasing saturation results from two effects: (1) ... the projecting shoulder between the concavity below and the convex slope above marks a hill-plain junction, ... episodic exposure takes on a regional aspect that implies long-term increasing relief amplitude and thus impacts upon general theory. The opportunity cost of 100 kg of rice produced on a land which can also produce 80 tonnes of wheat is: If the graph is concave downward (curved downward), the slope is decreasing. 1. The slope is decreasing, decreasing, decreasing, decreasing until that point, and then it starts to increase. Remember that the gradient of a line measures the rate of change of y with respect to the change in x.

Important: Probably the most difficult thing to understand about PPFs is that the slope of the curve is equal to the opportunity cost or trade off of changing which goods are produced.The most basic PPF is a linear one, where the opportunity cost or trade off of switching between goods remains constant. This article consists of MCQ related to the topic “Central Problems of an Economy”. 1. 6. The above PPF shows that the opportunity cost remains constant as we increase the output of one good. First, it is important to define increasing and decreasing functions. ... or our PPC, it looks like a straight line. These rills cut closely spaced furrows of very small depth, which impose a slope profile the same as their own on the crests of the low ridges between them, and therefore on the whole furrowed slope … Since resources are use specific, therefore, each time when one more unit of a commodity is produced a larger quantity of the other commodity is required to be sacrificed. The point where a graph changes direction from increasing to decreasing (or decreasing to increasing) is called a turning point or inflection point.Turning points can be local maxima (high points) or local minima (low points). As we move down along the PPC, to produce each additional unit of one good, more and more units of other good need to be sacrificed. A positive derivative implies that the function is increasing; a negative derivative implies that the function is decreasing; and a zero derivative on an entire interval implies that the function is constant on that interval. The Sign of the Derivative Increasing, Decreasing, Stationary. Suppose the second derivative f is positive on an interval I.This implies that the first derivative f must be increasing on I, so the graph of f is concave upward on I.Similarly, if f 0 on an interval, then f is decreasing there and the graph of f is concave downward. 8. That is true. In other words, it states that inflection point is the point in which the rate of slope changes in increasing to decreasing order or vice versa. Locate any inflection points. Production Possibility Curve (PPC) is concave to the origin because of the increasing opportunity cost. 2. centration of wash into rills.
