Supernovas. First generation stars only had Hydrogen to convert into Helium. There were no other elements until the first supernovas and second round of star making occurred.
It's in 1st intercostal ( space between 1st rib and 2nd rib ) and 2nd intercostal space ( space between 2nd rib and 3rd rib)
a 1st class lever there are 3 types of levers, 1st 2nd and 3rd class. 1st: fulcrum between effort and resistance 2nd:resistance between fulcrum and effort 3rd: effort between fulcrum and resistance Fulcrum = a pivot point on a lever. Effort = force applied on lever Resistance = load 1st example:see-saw/scissors 2nd example:wheelbarrow/car door 3rd example:someone raking/ hockey stick being usued
i think its a 1st class lever pivot between effort and load = 1st class load between effort and pivot = 2nd class effort between load and pivot = 3rd class
The neck is 1st class lever because the neck is between the head and body
Ups doesn't have first class or priority. That's the USPS (united states postal service or post office for short). First class and priority are pretty much the same service but first class has a maximum weight of 13ozs. So a package has to go priority in order to get there in 2-3 days.
The difference between the 1st and 3rd generation iPod is slightly different. the cases will still work, the difference between the two generations is that the 3rd generation is slightly slimmer than the 1st generation.
Well, the 2nd generation version is thinner, and that's about it!
A lot slowerBack is differentDoes not support some appsNot as sexy
well the 2nd generation has built in speakers, youtube, access to email, and a bunch of other crap.
There are certain games that you cant get on the ipod 1st generation also you you cant update ipod 1st gen with the new softwares but with the 3rd gen you can carry on updating it.
Well, mainly its just an updated version and 1st generation doesn't have built-in speakers like the 2nd does.
the second generation is thinner and has better software
The 1st generation has a box shaped outershell while the 2nd generation has a more comfortable curved grip. The biggest difference is that the 2nd generation has external speakers that can be adjusted with the external volume control. The first generation does not. There are also minor changes like better graphics and a wider variety of apps.
Well... the difference between the 1st generation iPod Touch and the 3rd generation iPod Touch is SLIGHTLY different. The cases will STILL WORK!!! (you are relieved :) ) The difference between the two generations is that the 3rd generation is slightly slimmer that the 1st. The thing is the cases made for the 1st generations might me a little big... (by a few centimeters!)
The new ipod has a sleeker design than the first and has an internal speaker....with supposedly faster internet and better sound quality...

Our Sun is a population I star, that does not mean it is first generation - that title is held by population III stars. Our Sun is a 3rd (maybe 4th) generation star. See related question.
