Do you collect your pennies in a separate jar or piggy bank?

Two things: The jar will contain no air.... It'll be a vacuum. Unless it's very strong, the jar would likely be crushed by the air pressure in the room. Assume the jar *is* strong: so, it's going to be hard to get the lid *off* the jar.

If you did, then the air in your room would rush in to fill it, as there's pressure outside and none inside. There would be nothing *in* the jar (assuming it's still unopened) to fill the balloon with - the balloon will remain uninflated.

The moon hardly has an atmosphere. It's not that much different than the vacuum of space to be honest. The average daytime abundances of the elements known to be present in the lunar atmosphere, in atoms per cubic centimeter, are as follows: Argon: 40,000 Helium: 2,000-40,000 Sodium: 70 Potassium: 17 Hydrogen: fewer than 17 There's would be hardly anything in the jar.

It wouldn't float. EDIT: I hate douchebags that thumb-down everything that wasn't their answer. It must suck to be dumb, but don't take it out on us.

It's always obvious who it was...

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
