Which weighs more, a pound of feathers or a pound of gold?
130823
One pound of feathers is more than one pound of gold because the "pound" unit is different. The most commonly used system of weights in the US and Great Britain is the avoirdupois system, where 1 pound = 16 ounces. This is used for most solid objects, except for precious metals and gems; gold is weighed by a special system, called the troy system, where one troy pound = 12 troy ounces. Where one avoirdupois ounce is 28.35 grams, one troy ounce is about 31.10 grams. To convert from avoirdupois pounds to troy pounds, multiply the first by 1.2152 to get its equivalent in troy measurement. Therefore, one "pound" of feathers in troy weight is actually 1.2152 pounds (one avoirdupois pound), compared to one troy pound of gold. And the feathers win.\n\nOr in monetary terms, 1 £ won't buy you a lot of gold, it will buy a lot of feathers...

The feather is wider and has to push a larger amount of air out of its way while falling, which requires more force. The faster the feather falls, the faster the air has to get out of the way, which means it has to be accelerated away, via F=ma. At some point, the force required to accelerate this air out of the feather's way balances the force of gravity. The same happens for the pebble, but since it's smaller, a smaller amount of air has to be accelerated, so the force is small until the pebble is falling so fast that air has to be accelerated out of its way very quickly (large a) and so it also reaches a terminal velocity, but a faster one.

Okay...  let x = amount of gold to add.\n\n.583(50) + x = .75 (50 + x)\n\nwhich means .583(50) is the weight of gold in 14k gold (58.3% of 50dwt) + X weight of pure gold will equal 75% (18k) of the TOTAL weight (50 + x).\n\nfractionally it would be 14/24 (50) + x = 18/24 (50 +x)\n\nmultiply the equation by 24\n\n14(50) + 24x = 18(50 + x)\n\ncalculate\n\n700 + 24x = 900 + 18x\n\ncombine\n\n24x - 18x = 900-700\n6x = 200\nx = 33 1/3 dwt pure gold

Yes it is true! But, it REALLY REAAAAAAAAALLLLYYYYY a VERY small amount. The process involved to remove it is not cost effective. You would spend more money getting the gold than what it is worth.

Actually, contrary to what some people obviously believe, gold is really soft. If you can make a mark on it when you bite down, it is real.

You'd probably be killed by either one. A ton of anything falling on you would not be a good thing. However, if I absolutely had to choose one, I'd choose the feathers and hope that they were dropped from a great height. That way, maybe the air resistance would slow them down and scatter them enough that I wouldn't be hurt.

Mark: \nMoney. Normally means the silver mark, a measure of silver, generally eight ounces, accepted throughout medieval western Europe. Although they were sometimes "clipped" or "debased," the English silver penny contained a standard weight of silver and so could be traded across Europe. In England the mark was worth thirteen shillings and four pence, ie. two thirds of £1. Equivalent to present value of the Euro.

According to Google:\n1 ounce = 28.3495231 grams\n\nYou can double check this if you know that there are about 454 grams in a pound.  454/16 ≈ 28+ grams

Gold is sold by the ounce. Find out the cirrent market value for gold and that's where you get your price.

i would say into metals or energy! Because the price of oil and gold are just keep going up and up!

I bet you are looking for word play with the pounds, right?

Each bill weighs one gram (I actually weighed a 1, 10, and 20), no matter what demonination. There are 454 grams in a pound. So it would take 454, 20 dollar bills, or $9,080. Also the US Bureau of Engraving and Printing agrees with this calculation, check out the link.

A 3-4 pounder is something to be happy about, 12 pounds is a HOG! Your friend was expounding on a topic he knew little about.

That would be simple assuming the piles of gold were made up of similar pieces, like gold bars or coins of a supposed known weight and the scale was a simle weighing device instead of a balance type scale.  Take 1 piece from the first pile, 2 from the second, 3 from the third, and 4 from the fourth.  Weigh all the pieces.  The pieces from the good pile would weigh 10% more than the bad ones.  Assume each bar is supposed to weigh 1 ounce/gram whatever.  There are 10 bars on the scale (1+2+3+4).  If all of them were of the correct weight, then they would weigh 10.0 grams or whatever, but we know that at least 6 and at most 9 will weigh less.  If the pile weighs .6 ounces less than 10.0, then the real pile would be #4, because 4 weighed correctly and 6 did not.  The same logic applies if the weight is .7, then the third pile would be correct, .8 less means the second pile is real, and .9 less means the first pile is real.\n\nIf it was a balance type scale or if the piles of gold were gold dust, something else would need to be figured out.

Both are Same Weight , 1 Kg\nbut Volume is different

They both equal a ton!
