What causes the outer core of the earth to be in a liquid state?
Q. In the original question the answer is supposed to come from looking at a diagram. It says-What information from the diagram supports the theory that the outer core of the earth is in the liquid state? Diagram shows crust, mantle, outer core, inner core, densities, pressure, temp and depth below surface of the earth.

How can the rovers survive to the outer space conditions?Why when you send a laptop in the outer space?
Q. Why when you send a laptop in the outer space it disintegrates? How could the rover Voyager 1 reach one light-year? How can the rovers survive to the outer space conditions and travel so far without disintegrating and send us information from light-years away? What is the source of their energy? Why only Russia and USA know how to build them and other countries don't know?

How do I get an outer div to expand with the inner content in Firefox?
Q. It works fine in IE. The outer div, which is just the background color to differentiate from the page's background color, does not expand vertically (it has a width defined). The content inside the two divs within it will expand, and they expand, but the outer div does not. I can set the div a specific height, and the color will expand as it should. But I need the height to be based on the content, not set in the code. What do I do?

What happens to electrons in the outer magnetosphere?
Q. I know that the outer radiation belt gathers charged particles from the solar wind but how do these charged particles affect Earth at the ground level or do they?
Asked by ivorytowerboy - Wed Aug 1 20:56:57 2007 - - 1 Answers - 0 Comments
A. Particles trapped in the radiation belts get swept toward either of the magnetic poles, north or south, depending on their charge. There they collide with atoms in the atmosphere at high altitude, which makes for a pretty light show we call an aurora. They pose little danger to us because, a) this only happens at extreme latitudes where people normally don't live anyways, and b) the collisions in the atmosphere absorb most of the particles before they reach the surface.

A. you have to use that diagram that shows the sequence of layers of electron by Linus Paulin. you distribute the electrons into the layers according to how many they support until you get to the last layer. here is an example of the diagram: if you follow the arrows you will see that you end up with 1 electron at 3p plus 2 electrons at 3s.. a total of 3 electrons at the outer shell. (the small numbers indicate the max of electrons supported in that orbit) edit: what the guy above said is also right and more simple.

A. Okay! Time to learn! Grab your Periodic Table(or get where you can see one) and lets take a look! The rows(horizontally aligned elements) are called "Periods". H and He are in Period 1; Li, Be, B, C, N, O, F and Ne are in Period 2; K, Ca, Sc, Ti...

An atom's outer energy level, or shell, is called its valence level. That's what your looking for. In an electron configuration, the number (1-7) is the energy level, the lower-case letter (s,p,d,f or g)is the sublevel, and the superscript number (that's the little ones higher up than the others)is the number of electrons in that sublevel.

A. It depends on alot of different factors. The type of bacteria, the seriousness of the situation, the strength of your immune system. These all come into play when it comes to infections. With the help of antibiotics, the pain should go away in 2-3 days (not always the case), and you should be fully healed after a 10-day dosage. Make sure you don't stop the antibiotics (if you're taking any) before the prescription is up. Otherwise, the infection could come back stronger than ever, and the previous antibitiocs you were using may be rendered useless against the resistant bacteria.

Asked by ROFLMAOLOL - Mon Sep 28 17:13:56 2009 - - 1 Answers - 0 Comments
A. The valence electrons and outer electrons are the same thing. They are the ones in the highest energy level; in the case of nickel, the two 4s electrons. Oddly enough, the 3d electrons have a higher energy level than the 4s orbital, and so they may enter into chemical reactions along with the 4s electrons, but the 4s electrons are those that are lost first when nickel combines chemically. Notice that the most common valence shown by nickel (and other transition metals) is +2. That comes from the two 4s electrons being lost first. Hope this helps.

A. Do push-ups with your feet up on a chair. This will place the center of gravity slightly different and cause different fibers to be worked. Then do some push-ups with your hands slightly lower than shoulder width for the same reason. Also vary your hand placement from close together to slightly wider than shoulder width. And mix up all of these to help define the whole pec. Add some extra weight to your body so there is greater resistance during the push-ups. Do one superset to exhaustion every other day.
