<p>It was a bit harder than i thought it would be, but i did alright... i think</p>
<p>okay, the question: Why can't drivers see the road clearly when it rains?
Anyone know?</p>
<p>Can someone also refresh me on what the last Question was (took it in Hong Kong) It was on magnetism/electricity</p>
<p>even i think i did decent.. the answer to the question i believe is because the wet floor reflect light or something.. im not really sure..
not so sure about the last question..</p>
<p>for the question with the spaceship and the probe going at .7c and .6c, what was its speed relative to earth</p>
<p>0 < c < .1?</p>
<p>I really hope I got a 650+ 'cause I didn't prepare very well.</p>
<p>I skipped like 3 and knew (80% sure) maybe a little over half the questions... the rest I only had a slight idea of (40-50%?)</p>
<p>Sigh... I need this score to be good for ED to Rice.</p>
<p>You think it would hurt if I got ~600-700?</p>
<p>for the space probe thing:
i blv,</p>
<p>0.7c<x<c</p>
<p>nothing can attain the vel of light so the upper limit of c and since the other thing was moving faster as compared to the saucer so the vel of the thing should be greater than the vel of saucer,0.7c</p>
<p>hey what do you guys think 7 omits and 2 wrong translates into? (for Nov. Physics) Do you guys think the curve will be generous?</p>
<p>^You'll get a 800 if you did that well.</p>
<p>The curve is very generous.. you only need a raw score of like 60. So in your case, you would get 800 easily.</p>
<p>Question: Ball of mass x slides down curved track. Which of the following increase? Which of the following decrease?</p>
<p>Potential Energy
Force track applies on mass
Sum of Kinetic and Potential energy</p>
<p>does Potential energy decrease and the applied force increase, because the sum of KE and PE will stay the same?</p>
<p>potential decreases, force increases? sum of KE and potential never change right?</p>
<p>seemed like there was a lot of magnetic force, charge, eletric force questions on there. Kind of sucks, since those are my weak points. From what i heard usually theres more mechanics, dynamics, momentum and hardly any eletricity etc. It really surprised me</p>
<p>yea i agree and more thermo stuff than i expected</p>
<p>btw can someone verify my answers?^</p>
<p>1/9
1/4
4
9</p>
<p>Those were the answer choices to a question. does anyone remember what the question was</p>
<p>it was about a satellite orbiting the earth with a radius of 4R, I put 4g for the centripetal acceleration as the answer</p>
<p>I thought it was 3R from the centre of the earth, in that case, it would be 1/4. Please, can someone confirm this?</p>
<p>yea I put 1/4 also</p>
<p>can u pls tell me the logic behind this? i think it is 1/9 . f =k/R^2. R gets multiplied by 3. therefore f=k/3^2 => 1/9</p>
<p>the particle that got emitted was alpha rite?</p>
<p>I put neutron.</p>
<p>An alpha particle is +4 atomic mass and +2 protons.. which wouldn't work because it needed only a +1 for mass.</p>
<p>What was a positron again? I forgot.</p>
<p>And for the planet one I put 1/4 also. It can't be 1/9 because you have to account for the radius of the planet... so its 4R.</p>
<p>What did you guys put for the one where it gave you a table of distance traveled in increments of time? I think it said what would most likely represent this table. I put that it was frictionless at first then friction came into effect.</p>
<p>Not sure how well I explained that lol</p>
