<p>it was difficult but I think it will have a very generous scaling. I guess a score above 58-60 will be an 800</p>
<p>I recall Physics have about 70~80 questions (I can’t remember exactly), >58-60 to be 800 might be too generous. It seems that SAT II marks are probably prone to be inflated.</p>
<p>Is this for the international test, or the domestic test? I took the international version as I’m currently overseas. I thought the questions were fairly easy, but I had difficulty with the timing (I didn’t pace myself well enough). Still, I feel confident about at least 50 of the answer choices I marked - probably because I studied like crazy prior to the test.</p>
<p>D is taking the test as we speak. She’s a bit worried since there are a lot of E & M questions and her class hasn’t done E & M yet in any kind of detail. Second go for her in this - she took it last summer (bad timing) and didn’t do so hot.</p>
<p>I hope the curve is generous. I had very bad timing and omitted like 8 
and I legit studied! When do the scores come out.</p>
<p>Just got home in Central Time Zone.</p>
<p>Mechanics and kinematics was easy but I struggled with some of the electromagnetic conceptual questions. </p>
<p>Ask questions as they arise!</p>
<p>It seemed more built around tedious calculations than my practice tests were. Maybe there were a few more kinematics and dynamics things, which would be more about math than theory and would result in more time per question. </p>
<p>Does anyone remember the answers for the Earth to Moon spaceship question? I think I said the one with most force of gravity was the one right next to Earth and the one with least was the second point from the moon, but I was kind of shooting from the hip.</p>
<p>The problem went like:
The Earth is about 81 times the mass of the Moon. A rocket produces thrust until point A (right next to Earth), then only the forces of gravity act upon it. At which point is the force of gravity on the rocket most (question 1)? Least (question 2)?</p>
<p>I’m not completely sure of this part but I think the points are A, B, C, D and E. All the points are on a straight line between the Earth and the Moon. A is right next to Earth, E is right next to the moon, B is a quarter of the way from Earth, D is a quarter of the way from the moon, and C is in the middle.</p>
<p>Those were questions 7 and 8. I left 7 blank and guessed E for 8, the point right next to the moon, for the least gravity on rocket.</p>
<p>What about the problem with the frequency?</p>
<p>Can you remember anything else?</p>
<p>It was that with period ,from the first questions</p>
<p>Well, period is the reciprocal of frequency. I know what question set you’re talking about; numbers 4-7 or something. I don’t remember the specifics but I felt pretty good about my answers.</p>
<p>I’m not sure. One about properties of waves that I wasn’t sure about asked which property affects how much diffraction occurs at a grating. The choices were wavelength, frequency, speed, maybe period and phase. I said wavelength.</p>
<p>In general, frequency is equal to one over the period. Frequency is also equal to the velocity divided by the wavelength. Wavelength is velocity divided by frequency. Velocity is wavelength times frequency. You have to remember that frequency does not depend on medium, though, so if a medium slows the velocity, only the velocity and wavelength change.</p>
<p>i think that frequency was the answer for two questions</p>
<p>I agree with both of you. I said wavelength as the answer for comparing light and sound as they go through a doorway. I also think I used frequency twice</p>
<p>I think so too, if you’re referring to the same set of questions as me.</p>
<p>One I had trouble with showed a square of wire in a magnetic field. The field was directed into the page. The question gave three conditions (I,II,III) and asked whether the field would induce a current under each condition. I think choice I involved rotating around a vertical line down the middle of the square, II involved rotating around a horizontal line across the middle of the square and III involved rotating around a point in the middle of the square. I think I said I and II would induce a current, but it seemed like III should also hit perpendicular to the current. I didn’t think they would be that tricky though.</p>
<p>i screwed up big time. didn’t even answer half. marked like 20. gonna cancel…</p>
<p>III is wrong because in that case the induced current will have to be in the same direction(or opposite) as the direction of rotation because the current should only travel along the wire…which is not possible according to right hand rule…</p>
