June 2006 - Physics

<p>I said II, III, I, since for the first one, the net force was into the center I thought. I didn't learn it in class, but that seemed to make sense.</p>

<p>yeah if the motion stayed in a circle it would be II III I, but that was so weird</p>

<p>I said I for that one escuis.</p>

<p>resistance does vary with temp, right</p>

<p>definitely I. 99.9% sure.</p>

<p>No, temp doesnt matter I don't think. I wasn't 100% sure though. So it was definately I for the Kepler one? How about the pictures of forces? III, then II, the I?</p>

<p>what's I? which question?</p>

<p>anyone remember the jupiter question</p>

<p>temperature DOES affect resistance</p>

<p>absolutely.</p>

<p>I thought hte formula was p(L/A)? Or does p depend on temperature?</p>

<p>why did the big ball drop faster?</p>

<p>I guessed A.. which I don't even remember</p>

<p>was it bouyancy?</p>

<p>Greater gravitational force. Was the one with the bird really above the actual position? Can someone explain to me? I didn't really get it (I said it was inbetween the water's surface and the actual position).</p>

<p>Oh crap, I just realized I did it wrong. Darn</p>

<p>was the 2nd question (electron hitting TV) really KE?</p>

<p>damn it.. I put electrical energy..or something like that</p>

<p>the formula is (pL0)/A, but temp still affects it separately</p>

<p>Man. I skipped 3 and already got 3 wrong. Im in trouble.</p>

<p>It's not greater gravitational force because even though that's true, the acceleration would theoretically be the same for both masses.</p>
