hello I'm asking this question for my friend on Discord I'm wondering if you could help him get the answer WHAT AMOUNT OF HELIUM IN LITRES DO I NEED TO MAINTAIN AN ALTITUDE OF 11KM WITH A SINGLE HELIUM BALLOON. MAKE YOUR OWN ASSUMPTIONS ABOUT WEIGHT

Wondering how many helium balloons it would take to lift you up in the air? ... Note this is the minimum number of balloons you need just to take off the ground. To set certain altitude, use the second part of the calculator. ... the balloon and the string, we can approximate that every liter of helium has a lifting force of one gram.

it was given as a lesson and guide for prayer.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
