Answer to:
The earth orbits around the sun at approx. 18642mph. A shuttle uses approx 14,500mph to get out off earths gravitational pull. When a shuttle launches out off earths orbit, does it add on earths orbital speed or stay its own and why or why not? Yes it does add on the earth's orbital speed. HOWEVER, since the shuttle ends up orbiting earth, which travels at the orbital speed, this boost is essentially useless. If the shuttle didn't add on earth's obital speed, the moment it left earth, it would just stay in one spot, while the earth moved away from it along its orbit. However, the shuttle does use the earth's...

What happens to the initial reaction rate as substrate concentration increases? The reaction rate is given by [substrate]^N, where [substrate] is the concentration of the substrate and N is the stoichiometric coefficient in fron tof the substrate in the reaction equation. Ie, CH4+2O2 -> CO2+2H2O the reaction rate is a constant * [CH4]^1 * [O2]^2 More generally aA+bB+cC->products reaction rate is k*[A]^a*[B]^b*[C]^c

Answer to:
Do Khaki and light purple go together? Yes they do. An easy way to tell if 2 colours go together is looking at a colour wheel. If the 2 colours are on opposite sides, they complement each other (ie go well together). The colour wheel is yellow-red-blue. Khaki is beige, so it's close to yellow. Purple is the combination of red and blue. So purple is approximately on the opposite side as beige. Thus, they go together.

Shooting the enemy is a much better way of staying alive than hiding in a protective shell.

I have windows XP prof on a laptop with 17GB. I am using about 14GB of it. I am NOT able to delete or copy anything in Windows Explorer (not even right mouse . It just hangs (hour glass);eventually the screen goes blank for a few seconds. Why? Virus? Help Also, operating systems require overhead to run. Windows XP pro and new operating systems especially require a lot of overhead. It is possible the 3GB that seem "free" are being used by the OS. Try getting a larger hard drive. For XP pro, I suggest at least 40GB

What's the difference between digital and optical zoom? To add to the other answers: Never use digital zoom. If you decide later that you actually only want that one part of the picture, you can always crop it and enlarge it on your computer. However, if you use digital zoom, and you later decide that you wanted the rest of the scene, then there's nothing you can do.

Answer to:
WHY the heck do the AA batteries go dead after about 30 seconds of using my digital camera??? (Samsung digimax s600) What should I do? I have had the same problem. For me, it was probably because the camera was very very old, and was very inefficient at power consumption. For you, there may be a short circuit somewhere. Are the batteries very hot when you take them out dead?

Answer to:
How many "megapixels" should I look for in a camera for casual use (vacation shots, parties, etc.)? If you are looking for a camera for casual use, you shouldn't be concerned about megapixels. Almost all camera's between 100 and 300 dollars will give you good resolution. Instead, you should be more focused on ease of use. For casual camera, you should probably buy more of a "point and shoot" camera, rather than a very complicated one with a lot of settings you will never use.

Answer to:
What materials are in a digital camera? Lots of electronics. Glass for lenses. Metal and/or plastic for the case. Batteries and whatever they contain. Light bulbs for flash. CCD (ccd's are also very sensitive to heat, which is why they glare when you point them at an incandescent light bulb)

In the game of Big 2, If I play three cards of the same value, can the other person beat that with a for of a kind and a single card? My three cards do not include a double, just three. No, because the 2 hands are of different types. The one you played is of the triple type, while the other one is of the "poker hand" type (ie full house, flush, straight, etc). Generally, to beat a hand, you must play something of the same type. The only exception i've ever seen is that a 2 can beat a double (except a double 2). Some people play by this rule, but most people...

Does anybody know how to bend the fabric of time and reality, besides reaching light speed and stopping time? just wonderin. Time is actually just light, and light bends with space, hence the term "spacetime". Thus, anything that bends space will "bend" time. The best example is a black hole. Because it has such a high mass, it produces a lot of gravity. Gravity is the bending of space. For a black hole, its gravity is so great that even light can not escape. Thus, inside a black hole, light does...

Then, you will need software to record the music. You...

If Microsoft products have so many problems, why do most people use Microsoft products? A lot of people say that Mircosoft products suck. This is simply not true. The only reason why they SEEM to suck is because more people are using them. Thus, there is a greater chance someone will stumble upon an error. Also, I must agree that to a certain extent, it is that people are too lazy to change. Also, there is the issue of compatibility with most other computers.

Will it ever be possible for trains to exceed the speed of sound? The problem with trains is that they are extremely non-aerodynamic. Even the high speed bullet trains, with their pointed noses, produce much more drag than a typical fighter airplane. Also, at such high speeds, drag increases as a function of speed squared. So going twice as fast would produce 4 times more drag. At supersonic speeds, This would be a lot of drag, that the train would have to...

Could someone make a full-size train that uses a wind-up spring to power it? Also, a spring is not very efficient at storing energy, compared to gasoline or diesel fuel. Also, there is a question of safety. If fuel is left on its own, it will not do anything (ie explode). However, a wound up spring, if left on its own, would unwind instantly. In order to power a train, the spring would have to be wound up really tight. There would be thousands or millions of joules of...

What g-forces can jet pilots take, and can this amount increase with training? To add to the answer by anonymous, the number of G's you can sustain can and will increase with training. First of all, pilots are trained to tense their muscules to squeeze blood to the brain when you are experiencing positive G's (where you are pressed to your seat). Additionally, regular exercise will make your heart stronger and more able to pump blood to your brain.

Answer to:
How come airships (or blimps) made today aren't as large as the airships of yore? Blimps are only used now to make a platform that will float in the air. A helicopter uses a lot of fuel to hover. For these purposes, blimps are the cheapest. There is no need to use blimps as a form of transit, such as the huge Hindenburg (it burned down) because jets are much better.

Answer to:
Couldn't it be made possible for the pilot to gas all passengers to sleep to prevent a hi-jacking or plane takeover? Even at the possible loss of a baby, or young child on board, wouldn't this be better than arming pilots with guns? It would be ineffective. If airliners started using gas, then terrorists would simply bring gas masks with them. Even if border security stopped allowing gas masks on airplanes to counter this, think about it this way. If they can sneak weapons onto a plane, a gas mask is no problem.

Answer to:
On average, how many commercial flights DON'T crash every day? For the person who asked the question: Rarely do planes crash. The only reason why we hear about them is that because it is such a rare event, the media makes a big fuss about it. I have read several times that if you are going on a flight, the chance of your plane having an accident is less than the chance of your car being involved in an accident while you are driving to the airport.

Answer to:
Can an jet airliner jettison a jet engine or more during flight? No. One reason is because they are extremely expensive. Additionally, there is no need to. If the engine does catch on fire, the pilot/copilot can turn off fuel supply to that engine, and the fire will burn itself out in a matter of seconds.

When you travelling in a jet plane, why do objects on the ground look as though they are still or moving slowly? This is kind of a continuation of ErikaJ's answer. The reason why things seem to move slowly is because of how your eye works. First of all, the eye can not detect distance. If you close one eye, there is no way for you to determine whether it is a large box far away or a small box up close, unless there are other visual clues. How humans percieve distance is because there are two eyes....
