I'm not sure about the equation that's what I see in my textbook.
What you said about the element is what I meant I just didn't explain it very well...
so where does this leave me? Is comparing them by there mass incorrect? I don't really know what's different about them except like you...
I'm not really sure... that's pretty much where I am stuck... they have to be different somehow otherwise why ask this question... I guess one has more protons than the other right because its more positive... so I guess it comes down to the tiny amount of extra mass that one of them has... you...
I think I typed that funny, probably should be Fe^2+ and Fe^3+ With the 2+ and 3+ being tiny and up at the top. I believe it is the charge of the element.
Homework Statement
A sample of two different irons, Fe2+ and Fe3+, are accelerated by the same potential and then sent through the uniform magnetic field of a mass spectrometer.
a) Which ion moves faster after being accelerated? Justify your answer by referring to equations used in this lesson...
Does this make sense?
The impulse of your head hiting the ground without a helmit would be
J = mass of head * intial velocity - mass of head * final velocity
the final velocity in this case would be 0 since it just comes to an abrupt stop.
Where as if you place a helmet inbetween on your...
i've looked around there site a far bit, I'm looking into impulse now and trying to think of a way to connect it all with numbers. I looked at a bunch of stuff on the standards and I am still not really sure what to say exactly as showing some calculations...
I am doing a report on Bicycle Helmets and it's supposed to include calculations of some kind but as I am looking around and writing about it I'm not too sure what would be the best kinds of calculations to put into this that won't sound out of place. The report needs to tell about how it...
