The purpose of homework is for you to learn, so get off the computer and do it yourself.

I can never understand people blatantly asking for homework answers on message boards. If you've worked through the problem and shown your reasoning, there are almost always people willing to check your work or show you where you went wrong.

But to say (in effect): " Here's my blank homework page. Gimme the answers. And explain how you got them."

Ain't gonna happen, kiddo. The purpose of homework is to solidify concepts and reasoning in YOUR mind, not someone else's mind.

Break the problem up to get a better picture of what it is asking.

The worksheet is actually helping you. It is helping you through the steps and giving you formulas on how to do each step.

Go through the chapter in your book. It has examples on how to do it. Maybe not on how to do it exactly like the problem, but most likely in bits in pieces. Google similar problems. Not to find the answer, but to see the logic behind how the problem is being solved. Then, practice with similar problems in the workbook.

Here is a link that will help you out:

Outsourcing homework to India

They will do your homework for you (at a cost). Of course you will learn nothing and probably fail your finals but what the heck, beats thinking doesn't it?

Those problems are pretty darn easy. If you're having trouble with those, then wait until it gets tough.

LMAO.... just for grins I tried a Google search on the problem that was in the PDF..

"Manganese-56 is a beta emitter with a half-life of 2.6 h. What is the mass of manganese-56 in a 1.0-mg sample of the isotope at the end of 10.4 h?"

And came up with roughly 7,500 hits.

This person is not only lazy but clueless.
