All EM waves travel at the speed of light, but for example an Xray has more energy than a microwave.

So were has the 'extra' energy of the Xray come from? It can't be kinetic because both waves have the same speed

help please

Assuming the buckets are weightless, or their weight is negligible.

This is some weird conversion thing my mom needs for her company stock. I know it's odd...I have no idea what to do.

I'm assuming I put this in the right area...

Someone told me once that it is impossible, not matter the size of a piece of paper, to fold a piece of paper in half more than 7 times (or 6 times or something like that). Is this true?

All right so I've got this question asking how to correct certain formulas. They gave me Fe2O. Since Iron has a full valence, and oxygen needs 2 more electrons for a full one, would that formula be correct? Or is that even an ionic bond? Obviously since it's between a metal and a nonmetal (oxygen) then it ought to be ionic. But what should I do for the full valence? Sorry, it might be a stupid question but someone ought to know.

Ok, i just want to check if Im right

The number of dollars per month it cost you to own a car is function of the number of kilometers per month you drive it. Based on info. in an issue of Time magazin. the cost varies linearly with the distance, and is $366 per month for 300 km per month, and $510 per month for 1500km per month.
a. Write the particular equation expressing cost in terms of distance.

My answer: driven= -55/2 c+9540

D=driven
C= cost

If im wrong would someone please tell me why.
