please help me.. PLEEEEEASE.. ill love u 4ever
I'm working on my physics science fair, and I'm doind the errors (like you know when you have to calculate errors based on half the smallest increment).. well, you know how ur suppose to use only one significant digit for it.. what if my value of...
PLEASE! This is an emergency!
My biology science fair is due in four days, and I have a HUGE problem.:cry: I was suppose to get pills or liquids that contain hCG, then add different substances to it to see if the pregnancy test would still read positive, but when I went to the pharmacy today...
hmm.. I don't kno.. isn't Newton's law about the difference in temperatures between the two things? I need something that deals with surface area and heat loss.
Am I right, or am I just confused?
I am doing a biology science fair. Here is my plan: I am going to ask my pharmacist for HCG containing pills, and put them into 5 different cups - one which will remain as a constant I can compare the others to. To the other four, I will add different chemicals, then test them for HCG using...
Hi guys,
I'm doing a physics science fair, and I was just wondering if you guys know any cooling laws related speifically to surface area.
You see, for my science fair, I got three jars that had the same volume, but different surface areas. Then I filled them with hot water to see which...
