Can YOU answer my science questions?

Question

1. Explain how to use parallax to measure the distance to objects. (I understand what the question's saying, but I don't get what parallax exactly is...)

2. Where are elements heavier than hydrogen and helium made? (I can't find it in the book!)

3. What causes a star to die?

I'm sorry about your wife. :(

Answer 1

hmmmm

1 http://en.wikipedia.org/wiki/Parallax

I give up.

My life has fallen apart. My wife beat the dog doo out of a good friend of mine and I can't take it anymore. I split up with her yesterday and now I'm just kinda brain dead.

sorry. thanks for the shoulder.

2 are you referring to within a star?
3. when a star gets so violent it beats up everyone around it and they don't want to play any more, then its head gets so big and furious, but theres no one else around for it to take its rage out on, then it dies from lack of friends / fuel.

I guess.

minus the == signs ya got there "#2"
nice link though

"...1. Explain how to use parallax to measure the distance to objects. (I understand what the question's saying, but I don't get what parallax exactly is...)..."

To help you understand exactly what parallax itself is do this -- Draw a dark circle on the wall in your room (..don't worry, we won't tell mom who did it..) Stand about 10 feet or so away from that circle and look at it while you cover first one eye then the other. You should notice the spot appears to move back and forth slightly. That's parallax and is caused by the distance between your eyes. As to explaining how that fits in with measuring the distance to far away objects, a picture is worth a thousand words so go here ==>http://instruct1.cit.cornell.edu/courses/astro101/java/parallax/parallax.html

"...2. Where are elements heavier than hydrogen and helium made? (I can't find it in the book!)..."

Most of the heavier elements are "cooked up" within super-massive stars when they explode in an event called a 'supernova.' Until that explosion happens, the temperatures within the star just aren't quite high enough to produce heavier elements.

"...3. What causes a star to die?..."

Simply put, stars die when they run out of the fuel needed to keep their nuclear fusion going. When that happens, the star cools drastically and gravity squeezes them into ever smaller spheres. Some dying stars end up as white dwarf stars, neutron stars, or go supernova.

Answer 3

1) distance object=distance observer base/ tan(angle)
http://en.wikipedia.org/wiki/Parallax
2) they are made by fusion in stars
3) Its fuel supply gets converted to heavier elements that require more energy to fuse while simultaneously being in an environment of decreasing energy. As the fuel runs down the star contracts and collapses in on itself at an excellerating rate. This builds up energy to the point of a critical mass and BOOM!
