Firstly i need to heat a wire to around 20 degrees or over using a low power battery which could last up to 24hours. what kind of wire is easiest to heat up? would AA battery's work? what would be a long lasting battery source? can it be done? please help me! thanks

I just want to know if there is any theorem that can forbid certain degrees of freedom in the Theory of Everything. Supposed quantum mechanics and generel Relativity are just classical limits of a third theory and the theory of everything. Is it possible for applications of this Theory of...

Hey everyone, was looking for some input please! I just finished my Associates in Mechanical Engineering Technology and am looking to move on to my BS degree. I got accepted to Rochester Institute of Technology and Temple University. RIT has the traditional MET degree, while Temple has a BSET...

One common explanation of the concept of D.F. is this: Suppose you have n numbers (a, b, c,...) that make up a sample of a population. You want to estimate the variance of the population with the sample variance. But the sample mean m is being calculated from these numbers, so when...

In the UK, following the Bologna process, any undergrad degree taking 4 years, assuming sufficient amount of credits is obtained, one is awarded a Masters degree. A 3 year course results in a bachelors. Why is it that in the US, one is awarded with BS after 4 years of study? Is it because of the...

Trig right triangle solving question How do you know if you should pick tan, cot, etc for the last part? if b = 2 , A =40 , find a,c, and B I found all of them except for c , how do you get c There's a part almost at the end that goes like tan40 degrees = a/2 and Cos 40 degrees = 2/c Why do you...

Question #1: Can you have current in a wire without voltage? I was having a discussion with someone today and I said that it's impossible to have current with no voltage... He said, "oh yeah, well when I short this battery out, you will measure zero volts across it, but you've got all kinds...

Sorry this isn't for a particular question, just wondering if anyone knows how to determine degree of static indeterminacy (or degrees of freedom) in an arbritary frame? Any help greatlly appreciated thanks.

I know that 65° = pi/180 = 13pi / 36. But when I divide 65 / 180° I get. 3261. How would I convert this into 13pi/36 ? I know I am forgetting the basics..

Hi, I'm a total layperson, haven't taken a physics class since AP in high school. Trying to figure some stuff out for some writing I'm doing (poetry, bizarrely enough). So excuse if this question is super-simple or if the terms of the question are nonsensical somehow. "Degree of freedom" in...

Greetings, Are there degrees of quantum entanglement? After entangled particles interact with others particles do they continue to be entangled to some degree? Becoming less entangled the more interactions that occur? So that there is complex network of entanglements? If so, could it be...

Hey there, I'm still at undergraduate level studying Physics right now, but looking ahead at the possibility of pursuing a PhD I'm slightly worried about what some people are saying. I'm currently studying at quite a good university, but seeing as I wanted to do a year abroad to learn a...

Hi all, I'm currently studying Physics with Astronomy and Space Science in my final year. I've decided not to go for the Honors degree so I will be graduating with a general one in a few months. I'm sorry to admit that I didn't enjoy studying this (although I love the astronomy side of it...

I have read that many tea masters insist that when infusing a tea that requires less-than-boiling water, you should first let the water reach a full 100 degrees C and let it cool back down to the target temperature, rather than take it off the burner as it is approaching boiling. I think it was...

Hello Everyone! I'm currently in my last year of high school and my application dead line is coming up (Jan 12). I know that I want to study theoretical math, as I've always enjoyed it above anything else. But I also really like the more math heavy physics, and am thinking it may be a good...
