How does a Stun Gun work? How is it different from Taser?

Tasers and stun guns are built on the same fundamental concept: both employ a less-than-lethal electrical charge to ward off an attack. While both a stun gun and a Taser are considered the same weapon under the law, making them legal to carry in most states, there are some major differences to consider between these two types of self-defense weapons.

A stun gun generates a high-voltage electrical charge between two small prongs; when this electrical current makes contact with the body, a painful charge is delivered. The amperage, however, is too low to seriously or permanently injure an individual and yet is typically strong enough to briefly immobilize someone, buying you precious seconds to escape unharmed. Hence, this is a generally safe and effective self-defense weapon to employ.

A Taser also delivers an electrical charge between two electrodes; however, these electrodes shoot out from a compressed gas cartridge inserted in the Taser, which launches the two prongs up to 15 feet from the Taser, similar to how a gas-charged BB gun works. The electricity, then, does not pass directly between the prongs, but rather through conductive wires which are attached to the gun’s electrical circuit. Small barbs on the ejected electrodes are able to hook into an attacker’s clothing or skin, which deliver the electrical current. When these electrodes shoot out, they travel in slightly opposite trajectories so that when they attach to a target’s body, they create a larger field of electricity. This larger surface area of electricity traveling between electrodes is what not only delivers a painful shock, like a stun gun, but also has the ability to immobilize an attacker, potentially for several minutes, without causing unconsciousness. This superior, longer duration immobilization is why police and law enforcement use a Taser to subdue and apprehend bad guys. Taser® calls this ability their “muscular override technology.

How do Ants sense Food?

S ugar has a slight odor, particularly granulated beet sugar. While all species of ants can differentiate between a wide variety of odors, the smelling range differs from a few centimeters to meters. Desert ants can smell sugar from up to 3 meters. the food sources that ants cannot smell from a distance they 'smell' it (contact chemoreception) by touching it. So in a way, all the food they detect, they detect it by smelling. So yes, ants smell (although contact chemoreception is more like taste) the sugar. The ant colonies send scout ants to search for food in various directions, often up to a range of 100 to 200 meters.(Depends on the territorial boundary and time of the year). The scout marches steadily in less circuitous paths initially if it has memories of previous feeder locations. (Ants use visual landmarks, and a stereo-smell system to create an odor map and navigate) Periodically it will halt and look for olfactory cues. It will then take into a more circuitous rando...

What is the smallest possible Distance in The Universe?

In physics, the Planck length, denoted ℓP, is a unit of length that is the distance light travels in one unit of Planck time. It is also the reduced Compton wavelength of a particle with Planck mass. It is equal to 5.72938×10⁻³⁵ m (Lorentz–Heaviside version) or 1.61623×10⁻³⁵ m (Gaussian version). It is a base unit in the system of Planck units, developed by physicist Max Planck. The Planck length can be defined from three fundamental physical constants: the speed of light in a vacuum, the Planck constant, and the gravitational constant. It is the smallest distance about which current, experimentally corroborated, models of physics can make meaningful statements. At such small distances, the conventional laws of macro-physics no longer apply, and even relativistic physics requires special treatment. The smallest possible size for anything in the universe is the Planck Length, which is 1.6 x10 -35 m across. It is impossible to determine the difference between two locations less than one ...

What is The International Space Station?

The International Space Station is a large spacecraft. It orbits around Earth. It is a home where astronauts live. The space station is also a science lab. Many countries worked together to build it. They also work together to use it. The space station is made of many pieces. The pieces were put together in space by astronauts. The ISS consists of pressurized modules, external trusses, solar arrays and other components. ISS components have been launched by Russian Proton and Soyuzrockets as well as American Space Shuttles. The space station's orbit is about 220 miles above Earth. NASA and other space agencies uses the station to learn about living and working in space. The first piece of the International Space Station was launched in 1998. A Russian rocket launched that piece. After that, more pieces were added. Two years later, the station was ready for people. The first crew arrived in October 2000. People have lived on the space station ever since. Over time more pieces...
