How Much Helium Is Needed to Lift a 4000 kg Load with a 600 kg Weather Balloon?

    Balloon Helium
AI Thread Summary
To lift a 4000 kg load with a 600 kg weather balloon, the volume of helium needed must account for the total weight, including the balloon and the helium itself. The buoyant force (Fb) is calculated using the difference in densities between air and helium, multiplied by the volume (V) and gravitational acceleration (g). The user initially struggled with determining the weight of the helium but ultimately resolved the issue independently. Understanding the relationship between the weights and densities is crucial for calculating the required balloon volume. The discussion highlights the importance of buoyancy principles in lifting heavy loads with helium-filled balloons.

Helium Balloon Question...Help!

A 600 kg weather balloon is designed to lift a 4000 kg package. What volume should the balloon have after being inflated with helium at standard temperature and pressure in order that the total load can be lifted? density of helium .179 and air is 1.29.

I have tried looking at problems that are similar and I set it up like this:

weight total = weight package + weight balloon + weight of helium

weight total = Fb = (density of air - density of helium) V g

However i don't know how to find the weight of the helium?

Help greatly appreciated!

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
