<p>The one with the sun angle and the fence post and stuff. Are their seriously going to be questions like that on real thing?! Like am I going to have to remember what angle the sun is in during every hour of the day/!</p>
<p>You completely missed the point of the question.</p>
<p>The question was just a trick to get you to see the problem in terms of similar triangles. All you need to realize is that height is proportional to shadow length and then set up a proportion between the two shadows.</p>
<p>^Exactly. And if you wished to know, the sun moves 15 degrees every hour.</p>
<p>How could anyone have missed this question?</p>
<p>IQ, people miss questions all the time. And missing the question is a lot better than guessing and hitting the correct answer by accident.</p>
<p>By the way, it is the the Earth that is revolving. The Earth takes 24 hours to revolve 360 degrees, or 15 degrees per hour as you correctly stated. ;)</p>
<p>^Good point on the earth revolving. :p.</p>
<p>Always eager to turn the topic to physics (my day job): It is NOT incorrect to say that the Sun is circling the Earth – it is a question of choice of reference frame, and sometimes choosing the reference frame of the “stationary” Earth is more convenient. Other times, of course, it makes things much more complicated, like when you are trying to explain the motion of the planets in the night sky. [Though to be sure, on a standardized test, if someone asks you whether the Sun moves around the Earth, give them the answer that they are no doubt looking for!]</p>
<p>Now, I know why I often read your CC name as Kepler. :)</p>
<p>Would you not love a SAT question that starts with “The perihelion shown in the above graph indicates …”</p>
<p>Keller’s laws/Kepler’s laws – an easy mistake.</p>
<p>I will say that learning physics and learning how to deal with the SAT really have a lot in common. They both take great concentration and serious attention to the details. I often tell both types of students: read everything carefully and then don’t put answers that you know are wrong! You would think that advice is so trivial as to be unnecessary, but my experience tells me it isn’t.</p>
<p>Pckeller warped my mind of all perspective. </p>
<p>I am not an object in the universe spining; rather, the universe is the object around me spinning - I am stationary. When I walk, I am not moving forward, the universe is moving backward.</p>
<p>Mind*****ed lmao.</p>
<p>^Chiasmus ftw :);</p>
<p>My apologies. Hope it wears off.</p>
