I am in the manufacturing business and there are going to be two job openings in the near future: One for an estimator and one for a project manager. They are both on the engineering aspect of our "jobs". I was thinking about applying for them to gain experience with engineering. I have my bachelors in computer information systems and enjoyed math but have no other engineering experience. The HR manager said they would train me but I'm wondering if I would enjoy this side of manufacturing. What are the tasks these two positions would have? Has any one else switched from an assistant to something engineering?

If a number is raised to a negative power, is the answer always negative? For example, if I have 2 raised to the negative 2 power is the answer -4 or 4? Or if I have 2 raised to the -3 power, is the result 8 or -8? I'm a little rusty on my Algebra/Calcus. Please help...

I got pee from someone last night, I kept it in my car today under some clothes so it would stay warm (now it's raining and not very warm) I have to take my test in a few hours and I planned on hiding it on my body against my body but maybe running the bag under hot water first or something than taping it to myself, Is this going to work? It's a simple pee in a cup test but I need to know if someone can please help with any detail they could. Thanks!!!

i am trying to find a plant that i had a few weeks ago. From what i understand, it is a plant that is not indigenous to the US, but is similar in movement to that of the venous fly trap, in that when it is touched, the leaves will retract in a matter of seconds. it is more of a bush with stems coming from the main tree and on each offshoot/stem of the tree there are a row of leaves on one side of the stem and a row of leaves on the other side. if you stroke down the middle of the stem, the leaves on both sides will retract into each other. please help and let me know the name of it! thank you!
