**Economics**

Claculate REAL GDP GROSS DOMESTIC PRODUCT for each year (2005=100) Year p q p q 2005 $1 100 $2 50 2006 $2 150 $3 100

**economics**

The domestic economy's consumption possibilities curve can be greater than the domestic economy's production possibilities curve. Why is this true?

**Physics check**

An excited atom decays to its ground state and emits a green photon. If the atom decayed to an intermediate state instead, the photon emitted could be.... red or blue?

**Physics check**

The mass of an atomic nucleon (proton or neutron) is about ..... times larger than the mass of an electron. 33?

**Physics**

Supppose an atom has four distinct energy states. Assuming all transitions are possible, how many spectral lines can this atom produce? Answer with a number only.... ? have no idea

**Physics check**

Heavier atoms are not appreciably larger in size than light atoms because the nuclei of heavy atoms have more.... nuclear energy?

**Physics check**

The spectral lines for elements are sometimes called atomic..... spectra?

**Physics check**

ok,shat about several photons in a series of transitions to the ground state

**Physics check**

According to Bohr, an electron in an excited state could give off ..... a continuous cascade of photons for a high-level transition.

**Physics check**

In 1923, Robert Millikan won the Nobel Prize for discovering the mass of the .... electron?

**Physics check**

I checked out the website, thanks. These are multiple choice and the correct answer is not a choice. electron proton neutron nucleus

In 1906, J. J. Thomson won the Nobel Prize for the discovery of the ..... electron?

**Physics check**

nucleus?

In Rutherford's Gold Foil experiment, he bombarded gold with alpha particles and discovered the .... electron?

**Bio**

Might want to look them up one by one.

**Biology**

I believe they detected the proteins involved, they knew those long before they even knew what DNA exactly did or looked like.

**Math**

So this means that the original price had 20% or .2 of the original price added on. After that, the price was 54. So, 54=(.2x)+x because x is the original price plus the 20% of the original price. want to know something weird? x+.2x=1.2xwhen you add them, imagine a 1 in front ...

**Math**

It looks to be 0...

**Math**

do you have a calculator? divide 1 by 1/4 (or .25) and see...

**Math**

yes.

**Math**

b is the same as x, just a different letter. how do you think it would go if it said 12x<12

**Proofreading**

Okay, I skimmed through it and I get where you are going, but you see the part where it mentions credibility of the source? When you call the article casual, that can be misunderstood as average, inadequate, anybody's old paper. They just mean it doesn't have to be a g...

I love your beginning :). When you say "These reasons make it vital..." it sounds a bit awkward. Take that out and keep "It is vital for parents to help..." You could even begin it "For this reason..." You really were only giving one whole stateme...

**Math**

very good. See, you get it.

**Math**

yes!

**Chemistry**

Does a catalyst affect a reversible equation like the kind in my earlier post?

**in text citation**

It depends, but If you are quoting or paraphrasing, I believe you can say "blahblahblah(Frankenstein)." remember to put the period after the citation, no matter how you do it, with a title or name.

**Math**

Yes! You got it! If you check back with my line explanation, since it is underlined, you darken in the circle and draw in a line for every number less than 3

**mATH**

I got 4 when I divided 1 by .25 (.25 also means 1/4)

**mATH**

If this is underlined < that means it is less than and equal to. No line just means less than. I explained this problem earlier, it looks harder, but it's the same. Get rid of the number beside the x by division.

**Math**

Yes. Draw a line from -5 to 5 and fill it out from there.

**Math**

Not that I can think of...I think I remember using a line graph where you circle the number (2 in the last case) and since it is not equal to x, you don't darken it in, then draw a line that extends to all numbers less than 2. x is somewhere in there.

**Math**

yes! and dividing by 6 would make sense because it would read x<2 or x is less than 2.

**Chemistry**

You know, that is entirely obvious, I think I'm just making things too difficult by overthinking them. Thanks much for shaking me out of that stupor.

**Chemistry**

I am in an AP high school course and the teacher pulled a fast one on us by asking us what happens to K in an reversible equilibrium equation if the equation is flipped. K equations I am talking about go K=(Products)/(Reactants). The options were they take the square root of K...

**Proofreading**

You have excellent grammar and reasoning, but the first thing they taught me in high school is never begin a paper with "I'm going to write about..." or "This paper is going to be on..." Maybe that is the way they told you to write this paper, and if so...

**Science/Lab**

I was able to see that the cold water took longer for the diffusion and the hot water was really fast. almost half the time. I am assuming that it is because the molecules move much more quickly in the hotter water. Am I correct?

**Science/Lab**

Can anyone tell me what happens when you do the diffusion lab? It is the one where you take food coloring and drop it into hot, cold and room temperature water and tell the differences.I need all the info.... please help.

I have this exact question. It sucks. This is the worst class I've ever taken in my life. No joke. There's too much information to learn in one year and the review book even tells me that. It has ruined my entire junior year.
