Amazing facts about everything

How does the Arctic  Ocean freeze? Arctic sea ice is one that forms on the Arctic Ocean during the winter months. Pure water, which does not contain any other molecules, substances or impurities, freezes at 0 ° C (32 ° F). On the other hand, about 3.5 percent of the world's seawater contains dissolved minerals and salts. This additional material reduces the freezing point of seawater to about −2 ° C (28.4 ° F) because the freezing point depends on the number of molecules present in a solution, as well as the type of molecule. During the winter months, when air temperatures in the Arctic begin to drop dramatically, a deep layer of seawater begins to develop minuscule ice crystals; This dirty water is called Fragile Ice. Another drop in temperature causes Friesil's ice to become thick. Pockets of salty slash accumulate until they become so heavy that they begin to sink. This leaves the top layer of icy crystals with a significantly lower salt content. The freezing poi...

Amazon How does bulletproof glass work? When a normal pane of glass is struck, there is nothing to absorb the energy, and the weakly-bonded particles break apart, allowing a bullet to travel directly. To prevent this from happening often, hard, lexible plastic sheets, often Polyvinyl butyrals (PVBs) are sandwiched in between, and heated repeatedly and are known to tear the two together. When a bullet moves, the glass layers break. Normal, but as they break, force is absorbed and intermittently diffused by strong and lexible PVB. This slows the bullet down, preventing it from passing. The broken glass pieces stick to the plastic, causing them to lie away and cause injury.

What is comets? Comets are objects made of ice, dust and rock in the solar system. They have a hard core and long tail of gas and dust. Every now and then they appear within sight of the Earth, before disappearing into deep space. TWO TAILS When a comet becomes close to the Sun, its ice melts and forms two tails: one made of gas and one made of dust. Halley’s Comet Halley makes a full circle around the comet The sun every 75 years, and it has been recorded by historians for more than 2,000 years. Beyklem  which tells the story of the battle of hasting shows it moving in the sky In the year 1066. Circling the sun Comets revolve around the Sun. Their tails are always away from the sun, but in slightly different directions. As the comet is closer to the sun, the tail grows longer.

How do flare guns work? A flared gun works in the same way as any conventional firearms have a significant difference: it must ignite its projectile and raise it high into the sky. Typically credited to Edward Way, the first gun that could flare, was tested back in 1882 by the American Navy. When the trigger of a flared gun is pulled, a chain of events begins. First, the flare propellant is ignited as the gun hammer hits the detonator cap. The signal is then pushed out of the barrel of the gun via deflection regression, a subsonic combustion process, where pressure is produced by rapid burning of gases in a small space. It takes less time to ignite the propellant which is also sufficient to ignite. These items burn so brightly because they contain magnesium, an element also used in firevert. Other chemical additives can produce different colors. In some cases, the flare will also have an in-built parachute (usually for military use) that prolongs its collapse on Earth ...

World largest seal The name of the world's largest seal is SOUTHERN ELEPHANT SEAL This seal is also called BEACH BULLDOZER. The largest carnivore that breeds on land is ten times heavier than the male southern elephant seal polar bear. Males also weigh five times more than females. Elephants spend up to eight months in the open sea, traveling large distances in search of food. During a fishing dive, they can hold their breath for up to two hours - the longest for any marine mammal. SIZE:- 6½–20 ft (2–6 m) long; 790–11,025 lb (360–5,000 kg) in weight (males much longer and heavier than females) HABITAT :-Stony beaches and adjoining seas. LOCATION:-  Islands around the Antarctic and southern tip of South America. DIET :-   Fishes and squid. When the elephant seal dips in cold water, their heart rate decreases to circulate blood around vital organs. This dive reflex also occurs in humans, but is less effective.“At sea, elephant...

Why mars surface is red? The red color that we usually see in images of Mars is actually the result of iron rust. The rocks and soil on the surface of Mars contain mostly iron and a small amount of dust. Other elements such as chlorine and sulfur. The rocks and soil were then wiped out by the wind and the resulting dust was blown across The surface of the planet by the activity of ancient volcanoes. Recent evidence suggests that dust along with water also extends to Mars. By the presence of channels and ducts on the surface of the planet. The iron contained within the dust reacted with oxygen in the atmosphere, creating a distinctive red rust color, while the sky appeared red as the storms lifted up the red dust. Planet's atmosphere. This dust surface, which is between a few millimeters and two meters deep, also sits on top of a layer of hardened lacquer mostly composed of basalt. Iron concentration This basalt is found to be much higher than basalt on Earth, and ...

Where is the Kuiper belt? The Kuiper Belt, sometimes called the Edgeworth Kuiper Belt, is a circumstellar disk in the outer solar system, extending from the orbit of Neptune (30 AU) to about 50 AU from the Sun. It is similar to the asteroid belt, but as far as 20 times wider and 20 to 200 times larger. Like the asteroid belt, it consists mainly of small bodies or remnants, when the solar system is formed. While many asteroids are primarily made of rock and metal, most Kuiper Belt objects are largely made up of frozen volatiles ("Eys"), such as methane, ammonia, and water. The Kuiper Belt is home to three officially recognized dwarf planets: Pluto, Humia, and Makemake. Some moons of the solar system, such as Neptune's Triton and Saturn's Phoebe, have originated in the region. After the discovery of Pluto in 1930, many speculated that it could not be alone. The region is called the Kuiper Belt which was envisaged in various forms for decades. It was on...

What is the event horizon?  Black holes have three basic elements. In the middle of a black hole and to an infinite density is a singularity made of stellar matter. Outside the singularity is the inner space of the black hole, where the laws of physics as we know it are bent and broken, and where space and time are stretched and constricted Putty.  If your spacecraft has entered the interior of a black hole, it is too late for you. You are crossing the third component: the event horizon. It is also known as the Schwarschild radius, the part that tells us where the black holes are outlined in black. This indicates no return for anything falling next to it, as it requires a faster travel than the speed of light to cross again, as far as we know it is impossible. . No horizon is attributed only to black holes' just a remarkable phenomenon that they possess. According to some principles To control the expansion of the universe, there are regions that will never be obse...

which is the first high level programing language? The first high-level programming language was Fortran. It was Developed in 1956 by the IBM team headed by John Backes. Fortran Became commercially available in 1957. Names from earlier versions of the language through Fortran 77 were traditionally written in all capitals (Fortran 77 was the last version in which the use of lowercase letters in keywords was strictly non-standard). The capitalization has been removed with reference to new versions starting with Fortran 90. Official language standards are now referred to as the "Fortran" language rather than the all-cap "Fortran". Many of its compilers have been written, such as IBM (native), HP, GNU and many more. It cannot write more than 72 characters in a line. There is no semicolon at the end of the line. In this context, it can be compared to languages like C / C ++ which require a semicolon after the instruction is over. The development of Fo...

Do we know how many tigers are left in the forest? The International Union for Conservation of Nature (IUCN) records the population size of thousands of threatened species. Their i gures are estimates based on many surveys. Regional Conservation Body. It is a mixture of direct observation, cameras are found on water holes and draping or claw marks. The most recent i gures, which are from 2011, suggest that there are about 3000 tigers left in the forest. The tiger has been listed as endangered in the IUCN Red List since 1986. As of 2015, the global wild tiger population was estimated to number between 3,062 and 3,948 mature individuals, down from around 100,000 in the early 20th century, with most remaining populations. Being in a small pocket separates them from each other. Major causes of population decline include habitat destruction, habitat fragmentation, and poaching. This, coupled with the fact that it lives in some of the more densely populated places on Earth,...

How do electric eels hunt? The electric eel is a formidable freshwater predator, capable of emitting a powerful voltage of electric water to submerge the passing water. The release of electric pulses has a direct ef ect on the muscles of the i sh, causing them to twitch or convoy, turning the predator away from their position. Electric eels are capable of this feat because they have electric parts that can store electricity like batteries. When an eel plans to attack, A burst of electricity up to 600 volts will discharge thousands of specialized electrocyte cells within its organs. Because of their poor eyesight, electric eels will use the same technology to navigate hunters' wards and their gloomy freshwater surroundings. Electric eels have three pairs of stomachs that produce electricity: the main organ, the Hunter's limb and the true limb. These organs make up four fifths of its body, and give electric eels the ability to produce two types of electric organ...

Why do dogs lick people? Ever wondered what your canine companion is after? Although it is believed that dogs lick humans to show affection, there are several other theories to explain the behavior. One is that we taste great. Salty sweat and food residues not only look great, but also give information about where we are and what we have eaten. Lick is also considered a learned behavior. Puppies learn to lick to keep themselves clean, but also communicate to greet each other and strengthen relationships within the group. In adult dogs, licking is also a way for a dominant pack member to show humility, so it is likely that dogs lick us for the same reasons.
