A rocket can be an aircraft, spacecraft or a missile which is propelled by a rocket engine. A rocket engine works on the principle of Newton's Third law, that is, for every action, there is an equivalent and opposite reaction. Rocket propellant is the fuel which burns and produces thrust to propel the rocket.The propellants are usually fueled together with the oxidants. Oxidants are required to burn the fuel efficiently. Thus the chemical reaction in the combustion chamber produces the required energy for thrust.The propellant is burnt in a controlled manner in the combustion chamber of the rocket engine and ...

Neptune is the coldest planet in the solar system as Pluto has been excluded as it was regarded as a dwarf planet. It is the eighth and farthest known planet from the Sun. It has 17 times the mass of Earth and is the fourth largest planet in the solar system. It takes 164.8 years for Neptune to finish one revolution around the sun and the elliptical orbit of Neptune is inclined 1.77° compared to that of Earth.Voyager 2 is the only spacecraft that visited Neptune. It analyzed Neptune's rotation, tilt, weather conditions and also its moons and ring systems.Physical ... Read More

Robonaut is a NASA robot, which is designed as a humanoid. The artificial intelligence makes it easier for Robonaut to do the same jobs as a human. Robonaut could help with anything from working on the International Space Station to exploring other worlds. The core idea behind the Robonaut series is to have a humanoid machine work alongside astronauts. Its form factor and dexterity are designed such that Robonaut can use space tools and work in similar environments suited to astronauts.These new space explorers won’t need space suits or oxygen to survive outside of the spacecraft. Thus they might help ... Read More

Both scramjet and Ramjet are types of jet engines. A ramjet is an air breathing jet engine which is usually associated with supersonic transport. Ramjets can start at supersonic speeds only, so as a result they cannot be started at zero velocity and cannot produce thrust as there is a lack of airspeed.Hence assisted take off flights or rockets are needed to or accelerate it to a supersonic speed from which it starts producing thrust. This makes ramjet engine to be efficient only at supersonic speeds as it can accelerate to speeds of about Mach 6. Ramjet has revolutionized Rocket ... Read More

A turbojet engine is used in Aircraft. These are air-breathing engines which suck in air from the atmosphere for combustion. It has various components like inlet, compressor, combustion chamber, turbines, and nozzle. Air is drawn into the turbojet engine, compressed, mixed with fuel, and burned continuously.The exhaust product of this burning operates the turbine for the compressor, producing thrust which propels the aircraft. Turboprops are used in smaller and slow-paced air crafts as turbojets are not efficient at low speeds whereas turbofans have better specific fuel consumption than the turbojet. These engines are generally installed below the wings or near ... Read More

Quantum figuring contemplates hypothetical calculation frameworks (quantum PCs) that make coordinate utilization of quantum-mechanical marvels, for example, superposition to perform operations on data. Quantum PCs are unique in relation to binary digital PCs in light of transistors.While regular advanced registering requires that the information is encoded into twofold digits (bits), each of which is dependable in one of two distinct states (0 or 1), quantum calculation utilizes quantum bits, which can be in superpositions of states. A Quantum Turing Machine is a hypothetical model of such a PC and is otherwise called the general quantum PC.What are they?Starting at 2017, ... Read More

Choosing which out of Hike or Whatsapp is better depends upon so many parameters which may be used for comparing them.Comparison b/w Hike or WhatsappAccessibility: There are so many of our friends, relatives who are already on WhatsApp but not on Hike. So in order to talk to them, we cannot ask them to install hike first. Thus, in this case, the accessibility and availability of WhatsApp are more than Hike.Popularity: Both WhatsApp and hike are popular, but for different purposes. The hike may be charming for its nudge feature, while WhatsApp for its video call facility. While hike may ... Read More

Chatbots − Little bots can answer questions and give information based on queries in natural written language. It is also possible to place orders with them. Many companies already use chatbots. Among them are Uber, Sephora, KLM, and Whole Foods.Microblogging − Short message postings from a social media account. Facebook statuses and Twitter posts are two examples.Tweeps − Twitter + People = Tweople. Twitterati is also used for Twitter users.Meme − A means of taking viral concepts and making them everyday lingo.User-Generated-Content (UGC) − An article describes UGC as being Latin for "crap" which is, quite frankly, well-put. UGC is ... Read More

This question occurs in our minds when we have to transfer files and all old methods start giving us enough troubles. The one way is to synchronize your phone with the USB cable, but you cannot carry the cable everywhere. You can transfer your data through email or other conventional methods, but again these tricks come with a lot of mess. However, you can get this done through some easy tools mentioned here:Push BulletYou can connect your phone and PC completely with the help of this tool, which also gives you a feeling that both your device and PC are ...
