Would an acidic "atmosphere" remove oxygen from the area it affected? By that, I mean, if you could make an area of air acidic, would it suck oxygen away from the surroundings?

They must be the same.

Homework Statement If the translationa speed of the water vapor molecules (H2O) in ir is 648 m/s, what is the translational rms speed of the carbon dioxide molecules in the same air? Both gases are at the same tmperature. Homework Equations V^2 = (3kT)/m The Attempt at a Solution...

The future? That's perfect. Thanks.

I need help thinking of ideas for slides. I have "How it works", "benefits", "challenges", "Physics behind it", "Hydrogen vehicles", "Why Hydrogen", "What is a fuel cell", "Uses", "efficiency", "Fuel cell configurations". I can't think of anything else.

I need to ask 10 opinionated questions about space exploration. I have 9, but I need ideas for the final one. My first 9 are as follows: 1. Do you think space exploration is worth the cost? 2. If you could, would you go into space as an official NASA astronaut? 3. If you could afford...

EMF = the derivative of flux vs time.

But what about it's value?

The induced current is counterclockwise.

I don't need to know the direction of the current, I need to figure out what it's equal to.

But I need an actual number for the equation to work. The flux would be decreasing, too?

It's actually slightly below 9.5 A The Magnetic field strength is decreasing.

A is the cross-sectional area of the wire.

Ok, thanks.
