hello,
So I'm currently enrolled in an MS physics program thesis option.This is my first semester and I have realized that I will not pursue a PhD. I know my university offers ms in physics with a profesional track to which I will have to do some form of internship. In the case that I decide to...
@Student100 Not really, sadly my GPA won't oscillate much at this point even if i get straight A's, and that is what I will graduate with. But to answer your question, I think I'll do better because when i got into college I came with no knowledge of how college was going to be. I got accepted...
@Mark44 I've taken scientific computing and advanced scientific computing which accumulated to 1 year of experience learning Python, plus in my senior seminar I had to write code for my project which took me about 6 months to get it done, and I am currently working in campus research doing more...
@Choppy so that means that eventually I will have to consider to go to grad school? but if I have such bad "major GPA" to which every university i this country will decline me. Why did I even consider getting a degree in physics if I could of gone to a technical school for the jobs you...
HI,
So I am graduating this Spring 2016 with an overall gpa of 2.91 and a major physics gpa of 2.54. I have talk with some of my physics professors about the possibilities of going to grad school, and they told me that it is up to me if I feel prepared, but based on my physics upper division...
What do you mean by monoprotic?? never heard of this before. hahaha!! All i know is that oxalic acid reacts with 2 moles of NaOH to neutralize the concentration.
Homework Statement

Never mind what i was doing was wrong i was subtracting .18-90 and the sine of that time 0.2m is .199m
but what hypnosam is doing seems right
I did y= 0.2sin[0.18(0)+90(0)-pi/4] but i just don't know how he got 0.707 when inmy calculator i get 0.013 for sin(-pi/4) wth.
Homework Statement
y=0.2msin[(0.18rad/m)x+(90 rad/s)t - pi/4]
What is the displacement at position x=0 and t=0?
Homework Equations
y(x,t)=Asin(kx-wt+phi)
The Attempt at a Solution
y=0.2m[0.18-90]=-0.199m
the answer is -.141 m help?

OK this is what I'm doing
1. cool to freezing point
q=(.250kg)(4186J/kgK)(273K-283K)=-1.046*10^4J
2.Freeze
MLf=(.250)(3.33*10^5)=8.32*10^4 J
3.Cool to final temp
Q= (.250kg)(2090j/kgK)(-283K-273K)=-2.90510*10^5
so when i sum up Q1+mLf+Q2= -2.177*10^5 J
Like seriously what am i doing wrong?
Homework Statement
How much heat is released when 250 g of water at 10 degrees celcius freezes into ice and cools to -10 degrees celcius?
Homework Equations
Q=mcΔt
The Attempt at a Solution
q= (250g)(4186)(283-273)=1.046*10^4 J
than q=(250g)(2090)(263-283)=-1.045*10^4 J
when i subtract...
