What are the advantages and disadvantages of a helicopter?
Many advantages. If you are asking for a project, then think about their application. They are extensively used across a range of services from Military operations, to air ambulance, Coastguard, Police and aid drops. They save many lives where other vehicles can't get to. They however have a limited range and fly time and cannot carry many passengers. All the talk of them failing and crashing you could say any form of transport can suffer so not really a disadvantage.
What are the advantages and disadvantages of range? [maths]?
Advantages - takes into account all values Disadvantages - It has no mathematical value and is affected by outliers or extreme values or skewed data.
What are the median advantages and disadvantages?
Mean, median and mode are used to quantifying central tendencies of any data/distribution. These numbers quickly summarize the data. So they are also called the estimates.Mean helps us to quantify average value in the data. (This is highly susceptible to outliers i.e. extreme values)Median helps us to identify the range of the data. i.e. 50% of the data lies below or above median value. (Median is also called as 50th percentile)Mode is used to identify most frequent values.Lets take an example. Consider number of children per household in USA.It would make sense to consider median and mode values but it also depends on the question we need to answer.Median will tell us how many children does 50% of the population has.Mode will tell us how many children most of the households has.Mean, for example, average number of children per household is 2.5… Does this number make sense? Can anyone have two and half children? ( Two and half men is possible… LOL :P). Then why do we consider computing averages in such cases?The averages are computed for conducting some statistical tests. Consider a scenarios in which we have to compare the number of children an American household and British household has… We conduct some statistical tests (t-tests etc.) to conclude are these number statistically significantly different or they are similar.So Median, Mode and mean has its own advantages and limitations. We must choose proper estimates to answer real world questions.Thanks,Heramb
What are the advantages and disadvantages of living in a densely populated region?
AdvantagesMore people to supportMore social contacts.Good local facilities.Better employment opportunities.Good public transport.Shorter journeys.Modern high-rise buildings also provide breathing space for more affluent urban dwellers.Great range of recreational activities. Best museums, art galleries, restaurants, shopping stores and libraries etc are found in the areas which have high population to support.Cultural diversity and intermixing of different cultures and ideas.Better public spaces.Better sense of community.Acceptance of reduced parking (use of cars and private vehicles will be lesser due to high density and overcrowding).Professional organisation of space (not always).Better accessibility to great range of goods and services.Greater ease of living.More economic growth than the regions which are sparsely populated.DisadvantagesCost of living is high.Poor sound insulation.Overcrowding and traffic congestion.Poor public transport.High land prizes and thus reduced affordability due to restricted land supply.Higher construction costs. As a result there are few leniencies for wasted space and clumsy designs when there is less room to play with.Higher crime levels. Higher densities means more people and mostly diverse population. This raises a possible concern regarding crime levels.Lesser green spaces and trees.Air and noise pollution.Hierarchical residential systems based on economic strata are developed in densely populated regions. Slums are one of the best examples.Beauty of local landscape is lost.
What are the advantages and disadvantages of free range farming?
The answer to this question is almost the flip side of your other question. Free range farming is more human to the animals, as well as better health of the animals. The disadvantages are less food produced and less profit for the farmer. The main advantage to me is free range farming is a more enjoyable life style for the farmer as well as the animals..
What are the advantages and disadvantages of WiFi?
Wi-Fi is an abbreviation of the phrase Wireless Fidelity.AdvantagesConvenientUseful for smartphones, tablet devices and other portable devices to connect at any convenient location within premises.SimplicityTo connect a new device with a network, simply turn on the Wi-Fi and do the simple configuration settings.MobilityInternet can be accessed from anywhere, ie. Bus, train, coffee-shop, super market, etc.ExpandabilityIt is convenient to add more wireless devices with current hardware settings without any cost and time.EfficiencyWiFi enabled devices are used at offices for convenient to access their files at any location and it gives more productivity for the company.Cost ControlIn WiFi network devices can be added without any cost unlike cables needs to be get man power to do the job.Standardization of TechnologyWi-Fi technology has standardized for all countries, it helps for the mobile devices to connect the WiFi regardless of the location.DisadvantagesPerformance/SpeedAlthough Gigabit WiFi is available in the market, we cannot get the gigabit speed at all locations. Now cable network has 10 Gbps speed.Connectivity/ReliabilityWiFi signal is depends on the interference. Ie. Concrete wall will reduce the signal strength. Also, there is a limit for distance to connect WiFi signals.SecurityWiFi router has various encryption methods to secure our network password. Need to be done proper configuration before use the WiFi network.What are the advantages and disadvantages of WiFi ?
Litmus paper advantages and disadvantages?
Litmus paper turns blue in a base (pH >8.0) and pink or red in an acid (pH<6.0). It remains purplish in a solution with a pH between 6.0 and 8.0 Advantages: It's a quick method to distinguish between acids, bases, and neutrals, because the colour change is fast. The equivalence point is between pH 6.0 and pH 8.0, so it's acid range is equal to it's base range. It's cheap. Disadvantages: The colour change does not indicate how strong the acid or base is. It doesn't work so well in non-polar liquids. People keep dropping the strips in the sink instead of the garbage.
