with any certainty that a meteorite, found here on Earth, is from Mars? With all the heavenly bodies out there, isn't it more probable that it came from somewhere else?
They don't know enough about the make up of Mars, to say the meteoric composition is identical to it, and they know virtually nothing of the make up of other celestial objects. Definitely not enough for an absolute comparison.

If you have a steel container with 2" thick walls, you fill it with water and weld a 2" plate on top you will have a strong container completely full of water.

If you then freeze this container how much pressure would be generated inside? Will the water still turn to ice? I know engines have cracked due to a lack of anti-freeze in winter and mountains are cracked via freeze-thaw.

Any ideas appreciated.

I read that debris, space dust and asteroids from outer space is constantly penetrating our atmosphere so does that mean our planet is getting heavier?

Or lighter? Because we are using up earth's stored fuels ie. gas, oil, coal.

Hi, i factorized this thing, and i would like to know if i did correctly and if there is any way to do it.

A=(3-2x)^2-(7x+2)^2
=[3-2x)+(7x+2)][(3-2x)-(7x+2)]
=[3-2x+7x+2][3-2x-7x+2)
=(5x+5)(9x-5)

Thanks


Thanks
