<p>how many points do you think i’ll get for the slit eperiment question if i didn’t include the equation but just said to measure the fringe length…? i set it up all correctly</p>
<p>That’s perceived weight not actual weight though as the spring scale is flawed. If you measured the whole thing with a scale, the weight would definitely decrease if you took the ball out of the water. Think of it this way, does the weight of an apple dunking tank filled with water weigh the same as if there were 100 floating apples in it? No.</p>
<p>You’ll get some points just not full points. We don’t know what exactly they’ll give points for though, so it’s hard to say. Maybe one or two points less than full?</p>
<p>does anybody remember the exact number they got for total weight of the entire apparatus?</p>
<p>55 Newtons.</p>
<p>54 if you use 9.8 for g</p>
<p>can anyone tell me if these answers look familiar?</p>
<p>25 m
.8 newtons
100 joules</p>
<p>MC was ok for me, a lot like what i was expecting…
FRQ was crazy though. i took an honors class and opted for the test, i got low 4s on the practice tests my teacher gave me, but it seemed like they took everything my class didnt get to and put it into the FRQ.
My favorite was the experiment question, i filled both pages with every detail i could think of about how to use a ruler to find the distance between the two plates. I just want a 3 I dont really care anymore. Oh and the second graph on the #2? FRQ i drew a nice heart beat moniter slowly growing smaller then flatlining and under said “this is me taking this test”</p>
<p>7 N was buoyant force right?</p>
<p>@Skorpius
Yeah, weight was 3N and tension was 4N. Buoyant force opposed them and velocity was constant (0), so buoyant force = weight + tension.</p>
<p>@failure
Hahahaha, those graphs were horrible.</p>
<p>failure i’m in the same boat as you…i’m a self-studied honors physics kid since ap physics isn’t taught in my school…all the topics i focused on were the topics that WEREN’T focus on this test …I was hoping for a 4 as my goal but i’ll be happy with a 3 on this … :P</p>
<p>I seriously just put “…i tried.” on my frq. For #3 I put the most illogical thing ever. I was about to say “just use the ruler” but then I knew that wouldnt be right so I started putting crap on that didnt make sense.</p>

<p>What pressure did you all get?? I recall like 2000 or 20000 Pa. (I forget which one exactly)</p>
<p>It was 2000 because I remember putting 2 kPa for some reason</p>
<p>1960 if you used 9.8</p>
<p>how come i dont remember anything…btw guys did we ask to calculate the electric FIELD or the electric potential for the copper sphere problem?? Thanks!! :)</p>
<p>I think my FRQ scores worked out something like this:</p>
<p>1 - 15
2 - 5
3 - 5
4 - 10
5 - 13
6 - 5</p>
<p>For a total of 53/80…i self studied this like 2 weeks before the test though so w/e.</p>
<p>I think i got 50/70 Multiple choice. 4 for sure, 5, maybe.</p>
<p>For the fluid pressure question, the weight of the whole contraption was just the sum of the different weights. I don’t really know how to explain it but i can tell you this, i weighed a bucket of water with apples in it, and then weighed it again with no apples. I then weighed the apples separately. The total weight of the bucket + apples = weight of bucket + weight of apples.</p>
<p>EDIT: Btw, would a 65% total be a 5? Would a 70% be a 5?</p>
<p>i think for this year’s exam…a 65%+ would be a 5</p>
<p>1 - 15
2 - 4
3 - 6
4 - 10
5 - 0 (used a ruler to measure width)
6 - 8</p>
<p>I got 67-68/70, is this a 5?</p>
