What are some simularities and differences betwee the pure copper penny and the copper/zinc penny? Why did they decide to change this? And how can you tell the difference (chemically and, hopefully, physically)?

I'm doing a science experiment. can someone help me that if u have 3 balls that weigh each differently, ( none is heavy, one weighs medium and one is light weight), and i pushed them all with the same force, and my hypothesis is that the heavy one is slowest, but it was really the opposite. so, to write a conclusion , how does mass affect the speed of the balls.

As it rises it gets orange, then yellow. Eventually it is white. I know it has to do with the electromagnetic spectrum and red is the longest wave length. What conditions make it appear red?

The earth moves at tens of thousands of kph around the sun. The sun moves at hundreds of km/s around the milky way. (217km/s apparently)

The galaxy is measurable but the universe in unimaginably big. Is the galaxy moving around the universe at a far higher speed than this? Could this speed be depicted as thousandths or hundredths' of C?

If yes, would there be severe time dilation between different galaxies if they were travelling at different speeds?

let's say we play basketball on the moon, will the ball accelerate faster or slower when coming down. what about when coming up

there are 2 sides to the story,

the ball would accelerate faster:less air resistance

the ball would accelearte slower: moon has lower gravity and acceleration


so which stand is correct?

Are there certain parts of the country where they are more common, or are they found everywhere? I live in the Chicago area, and I've never known them to be around here, but someone else was saying that they are bothered by them all the time. I had heard of them in downstate Illinois previously, but never up here.

The things move so slow, they seem like they should be extinct by this point. If something tried to attack them, would they move fast enough to strike them with those huge claws they have?
