At what ratios would methane, ethane, propane, butane, and pentane combust in normal air? 

By looking at an image of an object, lets say the earth, with a diameter of 12,756 km. Can the altitude of the satellite at the time be determined. I was thinking that maybe you could using the length of the object in the image compared to the actual object assuming the the camera is not zoomed in.  

How much of the oil produced in the us is made into plastics? Also what types of hydrocarbons are used and are these found in shale oil?

Not the browse function just a straight up list of everyone on pandora radio.

I understand that positive gravity attracts matter, but how does negative gravity repulse it?

During the period of the shows and the movies the way they designed ships changed in Star Trek. Many of the designs fall into a similar architectural styles. Is there a name for these styles, if there are what is it?

People currently living in Wyoming that were born outside of the state.

More specifically, I was trying to find data in regards to the number of people per house hold, number of single person homes, number of family homes, and shared house holds (like a roommate and couples without children).

I looked through some US census data for 2017 and 2010 but could not fine this. What did find was total US population and number if total households.

Can a strong magnet stop a speaker from moving and thus making noise without breaking it. Can it just hold it in place.

Using a stronger magnet, can a magnet stop a speaker from moving, and thus making any sounds. Specifically wondering if this is possible without breaking the speaker.

We have these speakers that give off sound when unplugged. It sounds like a voice or something like that. its not spooky in any sense just odd. To me, it kind of sounds like walkie-talkie communications

I have been told by a astrophysicist that i talked to a while back that in small amounts atoms fuse in the upper layers of the stars atmosphere. What layer is this happening in?

What forces cause this? What inpact does this have on the stat if any? Thanks.

I have been told by the hosts of Astronomycast that, in very small amounts, the combinations of forces in a stars photosphere and/or corona sphere nulcear fusion occurs. I was wondering if a jupiter type planet with a lot of hydrogen was close enough to their parent star would this process occur here.

The matter and energy in each galaxy would collected together by dark matter and dark energy, i was wondering when two galaxies collide what happens to the dark matter. Does it scatter, quickly recombined, or nothing. I know our knowledge on dark matter/energy is limited.

I was thinking about how a spaceship could work in the real world, and I came up with this question. I was wondering if it is possible to have an object with a strong gravitational field in front of an object with a strong magnetic field. The gravitational field of the (what I am assuming larger) object would pull the (smaller) object while it would push with its magnetic field. I would like to imagine them slinking across space.
