Every polygon is either convex or concave. The difference between convex and concave polygons lies in the measures of their angles. For a polygon to be convex, all of its interior angles must be less than 180 degrees. Otherwise, the polygon is concave.
The difference between regular and irregular polygons:
1. All sides and all the interior angles of the regular polygon are equal.
2. Since, all the interior angles are less than 180°, therefore they are convex in nature.
1.Either the sides are not congruent, or the interior angles are not congruent, or both the sides and the interior angles are not congruent.
2. Since, one or more of the interior angles are greater than 180°, therefore they may be either concave or convex.
Finding the area for both regular and irregular polygons is different.
In case of regular polygon, it is equilateral and equiangular, we use a segment that joins the polygon’s center to the midpoint of any side and that is perpendicular to that side(APOTHEM) to find the area that is:
But, in case of irregular polygons, finding the area is quite difficult unless we know the coordinates of the vertices as each side and angle can be different.
A square is a regular polygon.
A scalene triangle is an irregular polygon.
Basically, the difference between natural and organic stems from an official designation set forth by the United States Department of Agriculture (USDA) for organic foods. In 2000, the USDA published its official positionon organic foods and made its production a matter for strict supervision and legal regulation. While there are several criteria for organic foods, in order to be labeled "organic," food must have been grown without the use of synthetic fertilizers and pesticides (with some rare exceptions), antibiotics, irradiation, genetic engineering, or growth hormones. According to the USDA, "organic" is a labeling term that denotes products that are produced under the authority of the Organic Foods Production Act. Additionally, organic farming involves growing systems that enhance biodiversity, biological cycles and soil biological activity.
On the other hand, natural foods have no legal or federal supervision at all, and are not defined by any law or criteria. While the USDA does require that products list their ingredients in descending order of concentration, there is no official stipulation for the amount of natural ingredients a food must contain to be deemed as such. A food labeled "natural" is usually considered to contain less preservatives and chemical additives than other kinds of processed foods, though since there is no way to legally supervise the product, no sure answer may be set forth.
A sonar System measures distance by determining the time it takes for sound waves to bounce off a surface
SONAR : SOund Navigation And Ranging
Its a device used to locate the position, distance and direction of objects under the surface of water.This device is fitted at the bottom of the ship.
Source : Ultrasonic wave producing object .
Detector : It receives the reflected wave and convert it into electrical signal.
d = distance betweeb source and object
2d = total distance from source to detector after reflection of wave
t = total time taken by wave to reach the detector
v = velocity of sound wave
If time is known then 2d can be calculated using formula.
Hence distance can be calculated from time to bounce off the surface
Differences between regular and irregular objects are:Regular object Those substances which have fixed geometrical shape are called regular objects.For example: Books,pencils etc.Irregular objectsThose substances which do not have fixed geometrical shape are called irregular object.For example: A piece of stone, pieces of broken glass etc.
Hope this helps...
Good luck on your assignment..
Regular cola is better
The banking industry has quickly advanced in the previous couple of decades. Banks have turned out to be worldwide foundations, working in numerous nations around the globe—and, maybe more significantly, online.
Present day customers have started to put more significance on the online banking capacities of their budgetary establishments, constraining European banks to dispatch new items and modify their digital systems to keep up. Less customers are visiting nearby offices; truth be told, there have been numerous reports asserting that online banking is the main source of the disappearing of neighborhood bank offices crosswise over Europe.
The greatest contrast between conventional banking and online banking is a physical presence: a traditional bank has a home office, just as territorial HQs, with branches situated over the nations in which it works. Numerous traditional banks work their very own ATMs, however littler conventional banks may combine to work a substantial number to share costs. Conventional banks, with their nearby offices, were at first picked for their benefit — for example which bank had a branch nearest to home — just as their eye to eye client administration.
Online banking is of most extreme significance to present day consumers.To remain aggressive and guarantee their customers are fulfilled, most customary banks have fused web banking in their administrations. Online entrances enable customers to view their balances, exchange cash, open new records and even apply for a home loan to purchase a home or contribute — which is all accessible 24 hours every day, seven days seven days not at all like physical branches. Online client administration, including email and talk and video call, have started to surpass telephone calls and visits to the bank's nearby office. Such administrations permit customers
