to lift 1 kg or 2 pounds you need 0.16 kg of helium so for 2000 pounds you need 160 kg of helium or 320 pounds at 1 atmosphere
In order to know how many people it would take, you would have to know what the activity it. While it may only take one person to murder someone else, it would take an army to fight a war.
To determine how many latex balloons inflated to 9 inches will cover a ceiling of 285 square feet, we first calculate the area of one balloon. A 9-inch balloon has a radius of 4.5 inches, giving it an area of approximately 63.6 square inches (using the formula for the area of a circle, A = πr²). Converting 285 square feet to square inches (1 square foot = 144 square inches) gives 40,560 square inches. Dividing the total area of the ceiling by the area of one balloon, you would need about 637 balloons to cover the ceiling.
It would take 80,000 years.
it would take about $170,243,286,935 to reach the moon proven by M.I.T
It would take thousands of balloons to lift up the average house, as houses are heavy and balloons can only lift a small amount of weight. The exact number of balloons required would depend on the size and weight of the house, but it would be an impractical and unsafe way to try to lift a house.
10000000 helium balloons
Assuming one party balloon can lift about 14 grams, it would take approximately 129 party balloons to lift 64 pounds. However, this is a rough estimate as variables such as balloon size, air temperature, and altitude can affect the lifting capacity.
It would take approximately 480 helium balloons to lift a 20-pound frozen turkey. Helium can lift about 0.04 lbs per balloon, so 20 lbs divided by 0.04 lbs per balloon equals 500 balloons.
The number of balloons needed to lift a child would depend on the weight of the child and the size of the balloons. On average, it may take around 80-100 helium-filled balloons to lift a small child off the ground. It's important to consider safety measures and proper balloon handling if attempting such a stunt.
To lift about 110 pounds it could take any where from 100 to 150 balloons to lift a person, a lawn chair, food, and many gallons of water. A man by the name of Kent Couch from Oregon demestrated this for us by flying from his home all the way to Idaho. I would'NT try this unless you have a parachute of some kind of device to help you have a better landing. The Balloons could be about the average party balloons (large ones) that are about 11in in diameter. Now remember this is very dangerous and could even be lethal.I hope this helped you.Thanks for looking--Tiana5701
It would take roughly 67 weather balloons to lift a 190 lb person. Each weather balloon can lift around 3 lbs of weight, so dividing the person's weight by the lifting capacity of one balloon gives the approximate number needed.
well it depends how much the person weighs so do this take the persons weight and multiply it by five the divide it by how many inches the balloon is around then last but not least you add how much time it takes to blow up the balloon (this is because different heilium machines have different presure gages) and there is how many balloons it takes to lift a person off the ground wit regular party balloons
assuming that temperature is constant and that we're talking about regular party balloons (a "regular" 2-gram party balloon can hold ~ 16 grams of gas), you would need 6,156 baloons to hold your weight in equilibrium. you would need an amount greater than this to actually lift you (the more extra balloons, the faster the lift), and this is not accounting for the weight of the string. extrapolated from: http://malaysia.answers.yahoo.com/question/index?qid=1005123102737
It takes about 300 balloons to lift 200 pound manballoon filled with exactly 1 sq ft of helium yields about 28.2g (upward thrust)453.6 grams/Lb453.6(1Lb) /28.2= about 16 blnsSo to get one pound off of the ground it would take about 16 balloons16x200= 3200it would take 3200 balloons to lift a 200 lb person....Only hoover not continually rise on account of the uneven weight distribution and the temp differences in each balloon helium isn't as buoyant when cold, unless the temp is consistant. Wind is a factor; as well as the amount of static charge in the air
One ... if its big enough.
The number of ducks required to lift an elephant is dependent upon the strength of the ducks and the weight of the elephant,
