To lift 400 pounds, you would need approximately 74.3 cubic feet of helium. Helium is lighter than air, so it provides lift when contained in a balloon.
You would need approximately 65 cubic feet of helium to lift 1 pound. Helium provides lift because it is lighter than the surrounding air, creating buoyancy.
To lift 200 pounds of weight, you would need to apply a force equal to the weight being lifted, which in this case is 200 pounds. This is because the force needed to lift an object against gravity is equal to its weight.
The lifting capacity of a balloon depends on its size, shape, and the type of gas used to inflate it. Typically, a small helium-filled balloon can lift a few grams, while larger balloons can lift several pounds. Specialized balloons used for scientific purposes or hot air balloons can lift much heavier loads.
To lift a 60 pound rock with a mechanical advantage of 4, you would need to apply 15 pounds of force. This is because the force needed is the weight of the rock divided by the mechanical advantage (60 pounds / 4 = 15 pounds).
The force needed to lift a weight of 200N would be 200N. This is because the force needed to lift an object against gravity is equal to the weight of the object itself.
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

Depends on the weight. Check the MythBusters website, they did an experiment on this.
That takes 80 foot-pounds, equivalent to about 59 joules.
depends how big the helium balloon is and how many
It won't - at some time the balloon would burst or become the same density as the atmosphere, so stop rising. The above answer is correct. At about 110,000 feet or ~ 21+ miles (when the shuttle was well into the stratosphere) the balloon will burst. However to get the space shuttle into the stratosphere it would take 2,029,203,000 liters of helium and would cost approximately $ 146,102,616. Assumptions: Space shuttle weighs: 2,029,203 KG 1 Liter of helium can lift ~ 1 gram. Helium costs approximately 7.2 cents per gram. According to the NASA website it costs $450,000,000 to launch a shuttle. Maybe they should look into using helium to get them the first 20 miles.

650 pounds
An empty blimp can weigh as much as 12,840 pounds. This is without being filled with helium. When full of helium the blimp may only weigh as much as 200 pounds.
To lift 300 pounds using two pulleys, you would generally need to lift half the weight, assuming the pulleys are set up in a way that provides mechanical advantage (like a block and tackle system). Therefore, you would need approximately 150 pounds of force to lift 300 pounds with two pulleys. However, the exact weight needed can vary based on the efficiency of the pulleys and any friction involved in the system.
