What does the formation of heavy elements tell us about the age of the solar system?
Q. What does the fact that heavier elements are formed from supernovas tell us about the age of our solar system? Part of my physics project - I need a few pointers as I'm a bit stuck! All I can think of is that it tells us our solar system is ancient because supernovas happen after billions of years of a sun being 'stable'. Is that on the right track? So if these elements are only produced from supernovas, then does that make them virtually non-renewable?

A. In the early days of the universe, all that existed was hydrogen, helium and traces of lithium. That's all. All other element were formed in the core of stars and was liberated when those stars went supernova. The heavier elements enriched the cosmic gas, which can then form solar systems and planets with a higher proportion of those. Therefore, given that our system has a fair amount of heavier elements (oxygen, nitrogen, silicon, iron, etc.) then it has to have formed from gas that had been around quite a bit (actually, estimations are that our sun is a 3rd generation star), therefore cannot be as old as the universe, since it had to wait for those 1st and 2nd generation stars to go supernova to provide the raw material. So, it is a (rela [cont.]

What should I do about an apartment complex unfairly charging us for an extra half month?
Q. We had several difficulties with them, including false accusation of property damage. We had a lease that ran through March. We called to see what kind of notice we needed to give about moving out, the assistant property mgr told us 30 Days. Now they are trying to collect pro-rated rent for April because they say we were supposed to give a 60-Day Notice. We don't feel that we should have to pay for thier mistake when we called ahead in advance to ask.

A. I don't know what state you live in, but almost all state have a Fair Housing Board that is governed by the state. You canusuallyy find them in thegovernmentt pages in the front of your phone book. Thirty day notice is the norm. Check out Legal Aid in your county or state also and a lot of states have a listing for renters rights too. If you call one and don't get the answer your looking for ask them who would know or who can help you. Google rental laws for where you live. Good luck. A lot of landlord will takeadvantagee if they can or maybe they don't know whats legal. There are usally firm laws reguarding damage. They cannot make you pay for normal wear and tear and they have to prove the other damages.

How do I go about purchasing a SIM card in the US for use in international European travel?
Q. I'm going to be traveling to Europe in a couple weeks, and I'm trying to get cell phone service while I'm there. I've got my hands on an unlocked GSM phone, but I'm curious how I go about purchasing a SIM card for use in international travel. I know that you can buy SIM cards for one country at a time, but can you buy a SIM card that will work in multiple countries? Are there any companies in the US that sell these SIM cards so that I could buy one before I travel? Thanks!
Asked by jackbellows2003 - Mon May 7 23:27:33 2007 - - 2 Answers - 0 Comments

A. Actually, torskie is somewhat correct. you will need an unlocked quadband gsm phone. Quadband allows you to use it anywhere in the world. But wrong about that you only need the phone. You do need a prepaid SIM card. And it's only possible to buy a SIM card for multiple countries IF that service is availble in that country. I'm posting a link at the bottom that lists a SIM card that will work in multiple countries; I hope this helps you.

Q. I have been living abroad for over 10 years and have never filed income taxes in that time. I don't owe anything, but I know I should have filed anyway, I was just too lazy to figure out how. Now I'm married and am expecting our first child in a few weeks. We're ready to move to the US but I'm worried about the tax thing. Will this be a major issue? Can I overcome this? Also, is it possible to live in one country but apply for immigration in another? We live in China, but my husband is from a small African country.

A. I assume you are a US citizen. If you did not owe any tax then failure to file is not an offense and there is no penalty. If your non-liability for tax depends on claiming the foreign earned income exclusion, then you need to file back tax returns for six years (although the IRS is not excluded from demanding earlier returns or claiming tax for earlier years, it generally does not do so, nor does it usually want nonfilers to bother with earlier tax returns). In general the IRS is glad to cooperate in nonfilers regularizing their status. If you work in China for a US organization or a subsidiary of one, then your spouse may be eligible for "expedited naturalization" irrespective of never having lived in the USA.

If you have an idea as to the amount of uranium you start with, and compare it with the ratio of lead to uranium you have now, you will be able to figure out relatively how old the rock is. It is all based on the half-life of uranium.
