This would explain why when they are playing at the same time, there was an odd but clear sound that they were not supposed to produce.
The reason for this is because whenever any objects vibrate or moves, it produces interference. When one object moves in a particular direction or changes its motion suddenly, there will be waves forming in all directions. If another object has these waves hitting them as well while moving around by itself then there will be interference which will result in having waves being lost or changed.
The concept of physics used is applied in the principle of interference. When two or more objects cause vibration or motion, there will be waves colliding with each other and either being canceled out or changed by a small fraction. This is an example of interference that can lead to many different problems down the road. less

Here when they both play the guitar simultaneously both of them produce waves of similar Frequency. These waves are produced interact with eachother & produce constructive & destructive superposition. This leads to amplitude at a few points to become double as displacement at that point is high. This leads to the loud noise as high amplitude is responsible for high sound. To avoid this they need to play different cords or change the frequency of the waves produced. less

the acoustic guitar synchronously,two sound waves were generated from two guiters at the exact same time.I mean each one produced the same sound wave and both the waves were in same phase.Now,what is phase!
If two waves have the same amplitude,same frequency and same wavelength,then it is said that both the waves are in same phase.
So when two or more same-phased
waves arrive at the same point (when both started playing their guitar),the waves superimpose themselves on one another.Actually the amplitudes of the wave superimpose.This term is known as-Superposition.So,the resultant wave will simply be the addition of the amplitudes of the individual waves.This superposition
produces Constructive Interference which produces a wave that has twice the amplitude of the individual waves.The higher the amplitude,the louder the sound
will be.
On the other hand,it can be said very easily... less

each other,the resulting amplitude is zero which is known as-Destructive Interference.It means the two waves cancel each other.Therefore,no sound will be produced.
From this discussion,it has been realized that when Sarah & Ali started playing at the same time,the sound waves generated from their instrument superimposed on each other and created the wave which had twice the amplitude of that individual wave.So a loud thumping noise was
generated.But their ear were get used to it slowly.So,it didn’t affect that much later less

actually this happens due to resonance frequency . this is the frequency where superposition of waves can generate. same happen in the case of Sarah and Ali frequency of both musical instrument match suddenly this create loud thumping noise.

in India. The local people alongside Sundarbans are completely dependent on this forest for their livelihood. They cut trees, catching fish, collecting honey, harvesting Golpata, etc. Above some of the work they are doing illegally. The main challenge is to improve their lives without degrading the Sundarbans if we will plan sustainably. Although economic gains are important, ecological and environmental issues must be considered in long-term development plans. The Sundarbans mangroves region is a UN Educational, Scientific, and Cultural Organization World Heritage Site, a Ramsar site, and a Class 3 tiger conservation landscape of global priority. If the local people will work jointly with the tourism board, some people will get a job like; tourist guide, driver guard, etc. They can accommodate tourists as well as provide some... less

So, they are highly dependent on forest. And the main reasons of this dependency are the mono-cropping characteristics of their agriculture, low literacy rate, lack of awareness, lack of facilities etc.
So, Govt. And other agencies Should focus on their education, sanitation and other facilities. As most of them are farmer and do fish farming can practice different agroforestry systems but for this, more researches should be done to ensure which crops, trees grow well in these areas because salinity is a big problem here. And obviously sustainable dams need to be built so that tidal water does not reach the locality.
If they get their needs which they get from Sundarbans, our forest will be safe. And those projects harm Sundarbans, they should be stopped. Besides Eco-tourism can be a safe way for economic... less

Where there are several roads for going one place to another, everybody uses the shortest path or the widest roads; that causes traffic jam.Dividing up the vehicles properly into roads can help everybody to get rid of the problem. For this, existing google map can be updated more (as it can already show which road is jam packed and how much time we need to go through that path) or new apps can be developed for this purpose.All drivers will be connected to the app or that updated google map for getting more details every minute to choose a path to avoid the chance of creating a jam. less

Cobra, mamba, viper, rattlesnake and many other venomous snakes send chill down our spine. Needless to say, their venom is deadly when injected! Love them or hate them, they always get our attention. Even though their venom can be deadly and kill a human, it may also help save lives! We already know that venomous snakes go through a milking process in which their venom is collected in a container and freeze dried. Their venom is later injected into an animal in small amounts. The animal then produces antibody to neutralize this venom. This antibody is later collected and finally prepped to be used by humans as antivenom. But other than making antivenom, snake's venom can help us in many other ways. If you were a scientist, how would you use snake venom in a modern and creative way to bring change in this world!

But researcher's somehow found their way out to use snake venom for the welfare of the humankind. It's a massive win for us in the field of medical science and bio-chemistry. But if we look at the compounds of snake venom, we can find some very interesting compounds which can be used to make some revolutionary effect on some growing sectors of modern world. Researching on snake venom, you can see that there is an enzyme called Phospholipase A2 which is common in all species of snake. We all have heard about biodiesel. One of the obstacles of biodiesel production is overuse of food which can create food scarcity in the world. In this case, Phospholipase A2 can be very much useful for enzymatic biodiesel production. Moreover,another compound called Factor-X activator can be used in developing diagnostic kit for research. There are also some other compounds too.

Pretty much all Bangladeshis's know him today as he had been doing agricultural/horticulture shows since the 80s. His job is to find out problems and solutions that many gardeners and farmers face. Horticulture can be difficult if there are harsh weather, large cost of farming technology, and transportation issues. In addition, beginning gardeners might get frustrated as it takes knowledge, time, effort and the perfect combination of water, light, temperature, humidity, and nutrients to grow perfect plants every time. Our quiz this week is, how can you invent a technology that can solve all these horticultural problems and speed up the horticultural process? Just a reminder, that the internet has tons of solutions to these problems, but we will award $3 to the person who comes up with the wildest idea that has not been mentioned anywhere.

The following to simple steps will make horticulture handy.
1. Just like "International Movie Database (IMDb)", we need to create a database for horticulture where every possible corps along with its most suitable natural property (humidity, temperature etc) and market values will be included.
2. Spreading soil testing labs locally. Even small labs can be set up in vehicles to go to distant places.
A farmer will get his soil sample tested from the nearest lab. He will enter his soil properties and environmental properties to the database through its API-generated mobile app, and the database will suggest the most suitable crop of highest market value according to his condition.
The database will also provide him the scientific methods to produce that crop which will eradicate the 'lack of sufficient knowledge ' problem. less
