can somebody pleaseeeeeeeee help me with my homework ???

Please rewrite your question it does not make sense. Why does the middle fall of?

I'm assuming that you're talking about a coin with a different coloured middle, like the Canadian toonie. When you put the coin the fridge, the two metals (inside and outside rings) will contract at a different rate. I've never done this experiment, but it would make sense that the metal in the middle contracts faster than the metal on the outside. If the two parts aren't fused together well, the inside will fall out!

That really sound odd. Have you personally tried this?

As in middle fall off. Are your referring to the actual middle of the coin or the middle layer of brass/copper?

i'm in straight forward terms 18, so i'm no longer possibly at your point, yet I agree. i did no longer have any cyber web get admission to till I moved to college. i could hear people say that they could use the cyber web for an essay on a e book, or something like that. individuals are lazy, (no longer all of them) and that i do no longer think of this is honest that they could get the comparable grade because of the fact the youngster that labored his butt off to do particularly nicely. i do no longer possibly understand. in step with threat you ought to have your scholars cite their artwork, or something. i won't be able to think of of the rest. I desire i ought to help extra. yet yeah, they are going to be working our us of a, and who is conscious, in step with threat they're going to commence doing their artwork. Or, bear in mind the saying, "cheaters on no account prosper?" they're going to proceed to attempt to have somebody else to the artwork for them, in spite of the undeniable fact that it won't final long, whilst it comes all the way down to it. the youngster that labored his/her butt of for this is going to circulate out in front and be the prosperer. (is that spelt appropriate?)

i say metal cannot withstand the temperature.
