However, when you go to countries that use kilograms instead of pounds, knowing the conversion rate helps you know how much to purchase to get the same amount regardless of measurement scale. Knowing the cost per kilogram, instead of per pound, also helps you calculate how expensive it will ...
you would have to travel much faster than a passenger jet. If you know anything about Apollo 11 orwatched the moon landing in 1969(the furthest extent of human exploration of space), then you might have heard that the trip took around three days. ...
Some of the latest controversy about water's properties lies in how ice behaves when it melts. Some scientists claim that it looks about the same as it does when it's solid, except that some of its hydrogen bonds are broken. Others claim that it forms an entirely new structure. So for ...

Water is made from liquid oxygen and hydrogen in the space shuttle's fuel cells (the fuel cells can make 25 lb (11 kg) of water per hour). The water passes through a hydrogen separator to eliminate any trapped hydrogen gas (excess hydrogen gas is dumped overboard). The water is then ...

When challenged again about Nikola’s hydrogen production cost by the TeslaCharts podcast host [25:00], Trevor repeats the question, compliments the host on asking the question, claims he has “so much experience” with answering the question, says he “knows the stuff better than anyone he ...
NASA's goal is to reduce launch cost to only a few hundred dollars per pound within the next 25 years. They believe one way to do that is to dump the more than a million pounds of liquid oxidizer that is currently needed for combustion. "Air-breathing rocket engine technologies have the...
For example, you could get a fire going and then hold a pot of ice over the fire until the ice melts. Related:How To Dig A Native American Dakota Fire Hole But this will require a significant amount of time and effort on your part. You will be much better served by taking action to...
How much does 1 kg of plutonium cost? Since the energy per fission from plutonium-239 and uranium-235 is about the same, the theoretical fuel value of fissile plutonium can be put at $5,600 per kilogram. Reactor-grade plutonium also contains non-fissile isotopes, reducing its value to abou...
