How To I Get My Message About Homework Out

My friend wants to copy my homework?

So my friend wants to copy my chemistry homework. We were given this assignment like last thursday and it's due tomorrow. It's a LOT of problems though (it's balancing chemical reactions). And my friend wants me to take pictures of my work and just send it to her. She keeps saying she understands it but cant concentrate or focus on it or whatever. But to me, I think it's unfair because I spent a long time working on it and it's not fair that she just gets the answers and no work! She said she would buy me starbucks for lunch tomorrow if i give the answers to her, but honestly i don't think that it's worth it. She could've gone to our teacher for help during his office hours but she didn't. And I mean she's a good friend and stuff but still. I already told her I would send her the answers (texting) but Im having second thoughts now. And I asked her to try at least like 10 problems and she was like well...could you still send me the answers? And then like 10 minutes later she asked if I wanted to skype, which means she isn't even trying them! I'm sorry this is so long. I'm just frustrated. Should I let her copy? Should I tell her no, even though I already said yes? What do you think?

ASTRONOMY HOMEWORK HELP!!!?

I really hate to just give the answers because I believe it is more important for you to learn, not simply have the facts to momentarily answer your homework questions. Tell me (via Edit>Additional Details in your question) which ones you THINK belongs in which section and why. And then I will edit my response to tell you if you are correct or incorrect and why.

--------------------------------------...
Added: No sorry. C does not match 1. The fact that the Andromeda galaxy (a local group member) is moving towards us contradicts or does not support the expansion of the universe. This is because the members of the Local Group are gravitationally bound (for now) and their own peculiar motions relative to one another is stronger than cosmological expansion. Incidentally, the Coma Cluster is NOT a part of the local group, and is not even close to us. You may be confusing our local group with the local supercluster of galaxies which our local group AND the Coma cluster both belong to.

In the case of section 3, I guess you are basically right, except perhaps for B. F: there are few galaxies moving towards us outside the local group. They would be a rare exception to the expansion of the universe. E: is an untrue statement. There is no difference in the speed of the galaxies in our summer or winter. B: is only true in an overall average way. The speed of recession is dependent on the distance of the galaxies receding from us.

Section 2: D: you have backwards. The further away the galaxy is the faster it is receding. And essentially, a galaxy twice as far will recede twice as fast as a galaxy half the distance. This IS how the expansion of the universe was deduced. G: is an untrue statement. The type of galaxy has nothing to do with how fast it is moving.

Since you made an effort to at least try to understand, I will now give the (to the best of my knowledge) correct answers:

Section 1:
A, B, D

Section 2:
C,
F (only if F is a fact which I am not sure how many if any irregular galaxies outside our local group are actually moving towards us. They're not very far outside of the local group if that is the case)

Section 3: Non-facts (fallacies) do not support nor contradict the expansion of the universe.
E, G, and probably F if no facts actually support it.

Need help with java homework?

Back with some more java homework help. I am close to being done with this assignment, but ive hit a bit of a wall, so hopefully someone can help me. The task is to use abstract classes and subclasses to create welcome messages. Here's exactly what it says:

Define an absrtact class WelcomeMessage with a method

public String getWelcomeMessage();

that returns a welcome message. Define 3 subclasses WelcomeEnglish, WelcomeSpanish, and WelcomeFrench, whose getWelcomeMessage method returns a welcome message in English, Spanish, and French, respectively.Write a test class with a method

public void print(WelcomeMessage msg)

that prints out msg. Add a main method that calls print 3 times, passing it welcome messages in different languages.

Now i have the WelcomeMessage, WelcomeEnglish, WelcomeSpanish, and WelcomeFrench classes done, and i will paste them below. I am having trouble with actually getting the different messages to print. Im pretty sure I have to make another class with a System.out.print message, but im not positive. Here are the 4 classes:

WelcomeMessage:

public abstract class WelcomeMessage

{
abstract String getWelcomeMessage();
}

WelcomeEnglish:

public class WelcomeEnglish extends WelcomeMessage

{
String getWelcomeMessage()
{
return "Hello";
}
}

WelcomeSpanish:

public class WelcomeSpanish extends WelcomeMessage

{
String getWelcomeMessage()
{
return "Hola";
}
}

WelcomeFrench:

public class WelcomeFrench extends WelcomeMessage

{
String getWelcomeMessage()
{
return "Bonjour";
}
}


And those compile with no error, so i just need to know how to get the print messages there, im just confused on that. Thanks if anyone can help.
