Any potential producer of a product or a service needs first to determine the need for such goods. This is usually done through companies that do research by contacting either the public through surveys, or to specific companies that might require those services. They also inform you as to what othe…r people or companies are also providing those services or goods, and if there is any available room in the market for a new comer. This then determines demand. This also determines the available supply to fill the demands. It is much like water always attempting to find equalibrium. (MORE)
Running/walking can be explained through newton's third law-for every action force, there is a reaction force that is equal but opposite in magnitude. The action force when you're running is stepping on the ground. The reaction force pushes your feet and goes foward.
The most obvious application of physics in DNA fingerprinting involves the separation of fragments of DNA based on their mass and charge. This is done in a "gel electrophoresis" apparatus that pulls the fragments through a gel using an electric field. The physics therefore is that of the electric f…ield, electric charge, and the resulting force to mass ratio. (MORE)
It is about isoelectric precipitation. This involves the principle on isoelectric pH of a certain solution. Casein has its isoelectric pH at 4.6. Therefore, it is insoluble in solutions with pH lower than 4.6. The pH of milk is around 6.6 which gives casein the negative charge and makes it a soluble… salt. Once you add an acid to the solution, the negative charge of casein becomes neutral, precipitating the neutral protein (casein). (MORE)

Answer . A proof of principle experiment is one designed to see if the idea is workable. Usually little if any data is collected.. Example: " I wonder what happens if I push this button?". Better example: " Can energy be generated by wind?" To do a proof of principle experiment, it would only …be necessary to generate "some" energy from "some" wind by "some" method. It would not be necessary to collect data or decide the practicality of a particular method. (MORE)
The melting point of a solid is the temperature range at which it changesstate from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. During the melting process, all of the energy added to a substance is consumed as heat of fusion. A solid holds together because …there are bonds b/n the molecules that make it up. Melting involves the breaking or weakening of these bonds. The exact type of bond depends on the substance (MORE)

A sonometer is an apparatus for investigating the vibration of a string or wire under tension. The equipment allows the length of the string and its tension to be varied. See Wikipedia entry 'sonometer' for more details
It is commonly used in Melde's experiment. A sonometer demonstrates the relationship between the frequency of the sound produced by a plucked string, and the tension, length and mass per unit length of the string. These relationships are usually called Mersenne's law after Marin Mersenne (1588-1648)…, who investigated and codified them. (MORE)
A variable represents things that are involved in an experiment.The control is the variable that doesn't change regardless of theexperiment.
The principle of change is involved in both the chemical and psychological processes of sublimation. It could be said in both cases to be instinctive within a set of given parameters in which a higher state is considered more acceptable than a lower, as when ice vapourises without passing through a… liquid state, and when expressions of love are maintained Platonically due to the inappropriateness and unacceptability of anything sexual in nature.

To draw valid conclusions from an experiment, there must be two kinds of conditions observed: 1. An experimental condition (the particular manipulation of a variable being studied), and 2. A control condition (the situation that unfolds without manipulating the variable being studied). Only comparin…g these two conditions will enable one to know that the factors changed by experiment are what led to the results of the experiment. For example, if you apply heat to water in order to produce steam (an experimental condition), you must also have some water that is not heated (a control condition) so you can be assured that water does not convert to steam simply because time passes without heat. In the social sciences, wherein it is common to study groups of people, the experimental and control conditions may be referred to as separate groups. (MORE)
Your goal here will be to dissipate the kinetic energy of the falling egg in some way rather than breaking the egg. Energy is going to be conserved, one way or another. Any of this energy that can be used to do work on something else is work that will not be available to break the egg. This means th…at you want to build a structure to surround that will undergo "controlled crushability". You want the structure to collapse without completely coming apart. Assemble your structure so that paper will tear, straws will bend, tape will rip etc. You will also want the structure to distribute any force that is applied to the egg evenly across the surface of the egg. The real issue here is "energy conservation". (MORE)

Galileo's experiment to show that mass had little effect on the speed of falling objects involved two cannonballs of different sizes being dropped from a certain height. This showed that, in a vacuum at least, falling objects fall at the same speed no matter their mass.
Distance and time mostly go together. And speed also goes along with these two.. Below are some equations related to distance and time:. Time = Distance / Speed. Distance = Time * Speed. Speed = Distance / Time. From this we can see that if any one of these three measurements are changed, one o…f the other two or both will always change. (MORE)

BACKGROUND INFORMATION: Parachutes are used as emergency lifesaving devices, to transport and deploy supplies, equipment and people and to assist in slowing down an object for landing. Food and medical supplies are dropped by parachute to disaster struck areas. Parachutes are used to drop very heav…y equipment onto land and life rafts and other survival equipment in air-sea rescue operations. Some high speed airplanes use parachutes to slow down during landing. During the early years of the space program, parachutes were used to slow returning space capsules after reentering the Earth's atmosphere. The X-38, the new escape vehicle for the International Space Station, also uses a parachute to assist in its reentry. Parachuting is also a sport! You may think of a parachute as a type of flying machine, but parachutes really do not fly. Parachutes are considered "deceleration" devices. Deceleration means "to slow down". A parachute allows for a much slower and safer landing. The first record of a parachute design was found in the notes of the famous artist and inventor, Leonardo Da Vinci. Dated 1495, Da Vinci, wrote "if a man have a tent of closely woven linen without any apertures, twelve braccia across and twelve in depth, he can throw himself down from any great height without injury." The word "braccia" comes from the Italian word for arm; so experts believe that "braccia" refers to an "arms length". Da Vinci sketched a diagram of a person floating down attached to a pyramid shaped parachute. (A pyramid has a polygon as a base and its faces are triangles - in Da Vinci"s diagram the parachute had a square base.) Even though Da Vinci's design was never built, many experts believe his parachute would have worked. Although several individuals claimed to be the first parachutists, in 1797 thousands of people witnessed balloonist Andre Jacques Garnerin parachute from his balloon over Paris. Garnerin's silk parachute looked like a giant umbrella and was "unvented" (there were no openings or as Da Vinci advised "without any apertures"). Unfortunately, Garnerin's parachute erratically swung back and forth (oscillated) as air first spilled out of one side of the parachute and then the other. To prevent this from happening, other early parachute designers added a vent or hole at the top center of the parachute. The vent allowed some of the air to escape and reduced most of the oscillations. This made the parachute more stable (helped keep the parachute along the same path). Parachutes were first used in balloon exhibitions. Parachutists would draw and excite crowds of people by performing stunts from an aerial balloon and then float down. At that time, people did not think of parachutes as an emergency life-saving device. The first parachute used in an emergency was in 1808 over Warsaw, Poland, when Jodaki Kuparento escaped from his burning balloon. Even with the airplane's invention in 1903 and rapid advances made in aviation before World War I (WWI), parachutes were still considered a stunt person's tool. During World War I, balloons and aircraft were used to observe and spot artillery and troop movement of the opposite side. Early aviators from both sides were known to wave and greet one another. Unfortunately, this comradery did not last. Although balloonists who were shot down used parachutes, pilots believed that their flying machines were far superior to a parachute. It was even considered "dishonorable" to abandon an aircraft and use a parachute. Pilots were shot down and could not escaped because there were no parachutes. Towards the end of the war, several Austrian pilots used parachutes to bail out of aircraft and were saved. Subsequently, both the Austrian and German pilots used parachutes and later the United States adopted the practice for pilots. After the war, the United States government supported the development of the parachute. As aviation grew and planes were surplused after the war, air shows became popular as did parachuting exhibitions. Different parachute designs were developed. As in most of engineering, these designs were used to solve a variety of problems parachutists experienced and to address different needs. These new designs made parachuting safer, strengthened the different parts of the parachute, minimized the violent oscillations parachutists experienced and allowed the parachute to open slower and reduce the sudden jerk felt by the parachutist. There were also different designs for different uses: high altitude, high speed, cargo, supplies, sport jumping. Slots and holes were added to traditional round canopies. These openings allowed air to escape through the parachute and provided more control. One of the most important improvements was the development of the parafoil in the 1970's. You can see how different the parafoil looks. Air inflates the parafoil which acts like an airplane wing and creates lift. Even the language changed: while you "jump" with a parachute, parafoils are "flown". Why do we need parachutes? You know that when you drop an object it falls down (towards the earth) until it hits another object in its path or reaches the ground. Have you ever dropped and broken a raw egg? Does the egg always break? If you drop an egg 1/4 inch from the kitchen counter, it probably will not break. The egg will probably not break if you drop the egg 1/2 inch from the counter. What do you think will happen if you drop the egg from 1 foot (12 inches) onto the counter or from a much taller height? The egg will break. Why does the egg break in this case and not when it is close to the counter? What's the difference? The difference is the force or more specifically terminal velocity (the final speed) the egg has. Newton's Second Law states that: Force = Mass X Acceleration What is mass? Mass is the amount of material an object has. In general the mass of an object does not change. What is acceleration? Acceleration is the rate of change of velocity. What exactly does that mean? Here's an example. Look at a car's speedometer. If someone is driving steadily at 30 miles/hour then they are not accelerating (speeding up) or decelerating (slowing down). If you start to speed the car up to 50 miles/hour, then you are changing the velocity and you are accelerating; if you apply the brakes to slow down, then you are decelerating. Believe it or not gravity is not really a force, it is an acceleration and on Earth it is about 32 feet/sec 2 . This same science principle applies in decelerating devices like parachutes and parafoils. The parachute decelerates or slows down the fall of the object. The speed as it reaches the ground is slow enough so that the parachutists (or cargo) is not hurt or damaged. In aeronautical engineering, different forces act on different types of air vehicles and devices. The forces of lift, drag, weight, and thrust act on an airplane in flight. These different forces all act on the airplane at the same time. Lift created by the wings keeps the airplane aloft. The thrust of the engine pushes the airplane forward. The drag caused by the air resistance tries to hold the airplane back; drag acts in a direction opposite to the flight path. The weight of the airplane pulls it towards the ground. Because parachutes do not have an engine, there is no thrust. Also parachutes (unlike parafoils) do not create lift. Parachutes have two forces acting on them: drag and weight. The weight pushes the parachutist down, while the drag acts opposite the direction of flight (up). So even though gravity acts on an object at a rate of 32 ft/sec 2 , if you do not account for the drag acting in the opposite direction, you will not calculate the forces acting on the parachute correctly. It turns out that in a free fall stable position, a parachutist reaches a terminal velocity of about 174 ft/sec or about 118 miles/hour. (This is before the parachute is opened.) This terminal velocity is reached within 12 seconds of jumping and the parachutists does not fall any faster. Once the parachute is opened, the parachutist begins slowing down. Although it will vary, ideally, the parachutist will land at about 14 miles/hour. The main part of the parachute is the canopy - the fabric which inflates. Strong lines attach the canopy to the harness which the parachutist wears. (MORE)
