Which of the following statements are true about the index of refraction of a substance? I- it is inversely proportional to the speed of light in the substance II- it depends on the properties of the substance III- it depends on the radius of curvature of the substance IV- It can have a value...

Hey SDN, I'm a non trad undergraduate Bio minor who's finishing up their pre reqs while working/volunteering in a clinical setting. I'd really like to take the MCAT this summer because I've been studying for a few months, and have taken all the gen chem, o chem, and bio chem pre reqs this year...

Why does a higher wavelength penetrate a tissue below the skin better? Why wouldn't it be a lower wavelength => higher energy that penetrates a tissue better? Thanks!

Passage says " The 4 strings of a violin all have the same length of roughly 12 inches. in an experiment students studied the 4 strings of an old violin and the four strings produced these frequencies string I : 196 Hz string II: 294Hz string III: 440 Hz string IV: 659 Hz The question asks "...

I understand how to use the E=hf / E=hc/wavelength formula, but this question threw me off because they give you the energy in terms of keV instead of joules and I'm confused as to how they get the correct answer. (I got the question correct, but it was due to an educated guess that ive never...

I am studying from TBR and I'm not sure I understand what the shock wave is. I know that shock waves occur when vobject > vsound but I don't understand what's happening to the pressure why is it increasing and then decreasing? Thanks!

I am a second year student at a reputable private university, and I feel like I am not being challenged enough to where I feel any satisfaction in doing well. I am a biology major, and the biology classes are an absolute bore. Adding onto that, the classes that I am most interested in, which...

So I'm a biochemistry major and most of my classes are biochem classes. I'm assuming that they will be added to my science GPA on my application, but will it be added to biology or chemistry?

Hi can someone help me with this question please! It's a passage but I will type out the part that we need: they gave us a circuit with a power supply- a resistor R1 and a capacitor with a solution of cell suspended in a solution known as a dielectric constant: they are talking about...

So I'm just wondering to what extent you need to memorize all the physics equations. I'm about halfway done with studying for physics and I have about 30 equations already. Do you need to know every equation, and every detail of it? Do passages provide equations at all? I'm just wondering if...

Hi all, So I am planning to apply during the 2017-2018 cycle. I've completed every pre-req except Physics and Biochem. I've recently completed my fall semester and due to personal circumstances, I did not do well in Physics I (C-) and did not grasp most of the concepts . My pre-health committee...

I took Physics I (calc based) at a university my senior year of high school and got an A (it was a real struggle though, I do not like the material). I'm now a junior in college registered to take Physics II (alg based). Is this doable? Should I be worried? How much of Physics I do I need for...

Hi! I just wanted other opinions on this matter:) I don't know if I should spend the summer taking organic chemistry (which would allow me to graduate a year earlier if I wanted) or physics - OR spend my summer continuing to do research, volunteer in some different things, tutor, and hopefully...

Hey guys, New to the forums and a bit on edge! Quick intro: exam 1/19, using EK and their 10 week study program, currently behind by 2 lectures (sigh. Working full time and was in school until a couple weeks ago). I'm doing well with my biology (scoring a scaled 127 on average for my 30 min...

Hello, I know that there are many posts like this, but I'd like an answer based on my current situation. So, out schools posted final grades today and, as you can see by the title, I made a C in physics. I made an A+ in a Biology elective, an A in Biochem I, and an A in Molec cell. I really...

Has anyone had any luck finding a winter session physics II course in NYC? I'm striking out! (a couple of the CUNY's offer physics I, but not II). I would also consider doing it in Boston if anyone knows of an option there, but NYC would definitely be better! Many thanks. (I know there have...

Which science class did you get the worst grade in? Please vote using the poll.

Hello all, I'm a recent college grad finishing up my pre reqs for med school to hopefully enter this upcoming application cycle next spring. I NEED to take Physics 1 this spring semester, and have found it at a local college I've already been accepted to. However, I just realized that, while...

I just want to help people. I am in Pre Nursing because you don’t need advanced math skills, nursing dosage and you are done. I don’t want to be that nurse who regrets not going for their MD/DO, but if I know that my math skills won’t cut it or it’s too late to catch up on them, I can live with...

Hi! I am currently a fourth year student specialised in Physics at Cambridge University. Even though I am interested in maths and physics, I have always felt the need to do something that has an impact on people. And over the past two years, I became increasingly interested in infectious disease...

I have to take Physics I & II over the summer or Orgo I & II to stay on track, so just in general which do yo guys think is worse to take over the summer. In summer I'll have to take physics labs so it's 5 credits in 5 weeks and another 5 for the second summer session. Organic chem lab is 2...

Hey Everyone, I am thinking about taking Physics 1 online at a CC. The final exam is proctored on campus, and I would take the lab portion at my university. Would this look bad to dental schools? Also how would dental schools know I took this class online? I looked at my transcript, and it...

I am a junior in college. Organic Chemistry I / Lab Physics I / Lab Calculus Abnormal Psychology Developmental Psychology I'm in class 9AM-6PM almost every day. I have organic lab twice a week and physics lab once a week. I have 3 typed lab reports due every week, and pre labs due, as well as...

Hey guys, I'm new here. Currently a junior math major, and physics/chemistry/biology minor. I took AP Physics in high school a couple years ago, and I'm just realizing now that many dental schools (including one of my top choices, UMDNJ) do not accept AP credit. It didn't occur to me that I...

I am selling the resources below for the price listed beside it, I will considered negotiating the entire lot for a fair price. I will update the ad when books are no longer available. These prices do not include shipping. I am located in the DMV area for anyone in the area. Examkrackers 101...

I just graduated this May and now work as a research assistant full time (40 hrs/week) at a hospital. I'm taking evening classes in a few weeks b/c I have to finish physics 1 & 2 (w/ labs) and biochemistry. Is taking physics 2 and biochem at the same time (spring 17) a bad move? I was hoping to...

Does algebra-based Physics II require a great deal of Physics I knowledge? Need advice... I plan to apply next cycle and take Physics afterwards next academic year. From all the threads I just read through, the consensus seems to be that D-schools "don't care about physics." I took...

I have a practice question that asks what the readout would be on a force sensor at the red dot if the arm of the apparatus were lengthened but F applied at the end of the arm remained the same. My thinking was the weight would increase due to the longer lever arm, but the answer says it will...

Hey all, I'm having a lot of trouble working through this physics question from coursesaver, mostly because I don't think the algebra of the solution is quite right: A 2000kg elevator is connected to a cable. What is the tension in the cable when the elevator is accelerating downward at the...

So sorry if this has already been posted, this is my first time hanging out here. I'm a rising junior currently taking Physics 2 over the summer at Georgetown University (have not taken physics 1) and I'm consistently doing badly in the class, particularly on the exams - I'm guessing I might...

Hey there! Was going through a couple of EK 1001 Physics questions and came across this question that I couldn't quite figure out so hopefully someone here could lend some much needed clarification. Here's a picture of the diagram and the question prompt: My attempt at a solution: a...

Hi All- I have been trolling these threads of late (as I am sure many people do) as I begin my journey as a pre-med student. To give you all some background- I am a 25 year old student (non-trad) that just graduated from University with a Bachelor of Arts in Psychology. I did very well in my...

can someone who recently took the OAT compare kaplans practice tests to the real oat? i am finding their physics sections hard and calculation based, is this an accurate representation of the real test

Hey, I'm an incoming high school Junior and I'm taking a Physics AP course this year. I'm wondering what Physics is really like. Is it more math based than theory based? How did you do in it in comparison to Biology and Chemistry? Also, what type of math does it use the most? Trig? Algebra...

I'm a rising junior premed. This summer, I am taking physics 1 at my university. Unfortunately, it is not going very well so far (2/3 exams through). I currently have a B in the course. The problem at my school is that physics counts as 5 credit hours, so it has a heavy impact on GPA. My GPA...

This post may be controversial, but I'm hoping someone with knowledge of the medical school inner world can answer. Why are two semesters of physics required? I feel like anything medically relevant in physics can be learned on the fly in medical school and undergraduates would be better...

Hi all! I submitted my AMCAS primary about 10 days ago. Though my advisor said that "fit [to schools] is more important in some cases than metrics," I would appreciate some help in balancing and broadening my top-heavy list. I'd love to attend where there are plentiful resources and lots of...

Has anyone taken these class with these professors at UC Berkeley Extension? Could anyone comment on the quality of professor and level of difficulty? I can't seem to find any recent threads on this... Genetics (online) with Susan Parkinson Immunology (online) with Monica Ranes-Goldberg...

Hi SDNers, So basically, I was having a bit of a trouble deciding when I should take Physics I and Physics II in college- I had originally planned on taking Physics I in my first semester of junior year and Physics II in the second semester but then I realized that if I want to take the MCAT...
