Answer: You need to get to a sufficiently high altitude or distance from the Earth to being to see the curvature. A minimum heihgt of around 60 to 70,000 ft is required to be able the see the curvature of the horizon.
Answer: The j curve is when the population pyramid has a lot of children and few elders. So the pyramid would look like a j for example Kenya would be a good example. because it has a great amount of children and as the number gets higher the number of people gets lower.
Answer: It starts off high (because of fixed costs divided by a very small quantity), drops until it reaches a minimum, and then starts to rise again as diseconomies of scale kick in because of higher marginal costs. This creates a "U" shape.
Answer: Bell curves are used because they represent an exactly normal distribution. A normal distribution means that all of the values are centered around a single mean value, with the probability density decreasing equally on either side of the mean. This is the distribution that is most widely used in statistics because it is often found naturally (truly random data follows a normal distribution), and also because it follows from the central limit theorem.
Answer: The usefulness of bathtub curve include the decrease failure rateas the first part, also known as early failures. The second part isa constant failure rate, known as random failures. The third partis an increasing failure rate, also known as the wear-out failures.
Answer: Depends a bit on conditions and whether you are driving a front or rear-wheel drive vehicle. Generally speaking, you should steer into the skid, and lift off throttle (in rear-wheel drive). In front-wheel drive, do not lift off throttle completely, but keep power on to pull you out of the skid. Obviously, as the car comes out of the skid, straighten the steering.
On ice, it is possible at low speed to control the skid by balancing the understeer generated by the front wheels by creating oversteer pulling on the handbrake. This can ONLY be done on front-wheel drive cars, AND AT LOW SPEED!.
Answer: ANSWER: Its called an airfoil. Its what gives the plane lift during flight.-------------------------------------------------------------------------------------------An airfoil is the totality of the wing. There are various designs of airfoils. One such design was of a wedge shape, which is contrary to the accepted design of the curved upper surface. The basic airfoil includes the upper curved surface of the wing, the bottom flat or less curved surface of the wing, the cord thickness and total wing span. I had given a more thorough lay explanation of how lift is produced, but for some reason that explanation was removed. Go figure? My past background is as a flight instructor/mechanic/cropduster pilot.
What is strength curve?
Relates to any exercise, Analyzes the components of strength production, Has seven factors
Answer: Marginal Revenue is the derivate (rate of change) of total revenue. Total revenue is = Price x Quantity. For instance, if the demand curve was Q = 100 - P, find the inverse demand (P = 100 - Q). Total Revenue = 100Q-Q^2 Therefore marginal revenue is the derivative of 100Q - Q^2. MR = 100 - 2Q (thus twice the negative slope).
In short: inverse demand x Q, find the derivative.Source(s):Microeconomic Theory Class
Answer: The relationship between these two curves is that a long run average cost curve consists of several short run average cost curves, each of which refers to a particular scale of operation. both curves are u shaped the short run avg cost curve rising because of labour specialisation and better spreading of fixed costs and it rises due to the law of diniminshing returns. the long run avg cost curve falls because of economies of scale and rises because of dis-economies. the long run avg cost curve must comprise of all the lowest points of each of the short run avg cost curve because no firm will operate at a level of higher costs in the long run than in the short run. the long run avg cost curve must always be equal to or lie below any short run avg cost curve because in the long run all factors of production can be variable.
Answer: movement on the curve is simply things going along as expected, like ok I want that and other people do too, so the demand curve is high. A shift occurs when the demand changes, like I found something new and everyone wants that thing now, so the demand for that other thing has shifted because nobody wants it anymore.
Answer: The material has to stretch (strain) first before it breaks. Forductile materials, when stretch reaches a certain point itpermanently deforms (yield) and continues to carry load until itthen breaks as load increases.
For brittle materials like glass which do not permanently deformthay simply break without yield.
Answer: Phillips curve defines the relationship between the changes in therate of employment towards inflation. This is an economic conceptthat shows how unemployment affects and raises the rate ofinflation.
