<p>Yes . Considering e/m ratio proton deflects by lesser margin.</p>
<p>300K … Not 200 i guess</p>
<p>what did you guys say for the tornado speed question?</p>
<p>I got 17m/s. The given speed of sound is 340m/s. First thunder was 20 seconds after lightening. Second was 18 seconds after lightening. 20-18=2s. 340m/s * 2s= 680 m traveled during the interval. There was a 40 second interval between the thunder so 680m/40s= 17m/s. I think this is right</p>
<p>hm. usually a 59 or 60 is still an 800. Was momentum conserved in all three cases. Isn’t it usually always conserved?</p>
<p>momentum wasn’t conserved in the last case i think, because it has to be conserved in both the x and y direction. So the last case was probably not even possible</p>
<p>For the question with the converging lens, was the image the same size but inverted?</p>
<p>Yeah, what is the magnetic field on electron? Is it down? Also there was a question involving proton and movement. The magnetic field for that is 0?</p>
<p>I’ve never taken SAT Physics before but it was really really hard
Is there anyone here who took it before? Was it harder than usual??</p>
<p>Do you guys think the curve will be rather lenient or harsh?</p>
<p>magnetic field on the electron was out of the page, cuz velocity was forward and u wanted the force to point downwards. So u just had to use right hand rule. And ya I also put no force for the proton cuz it was moving in parallel to the field.</p>
<p>I thought it was way harder than usual, there were so many weird questions that I’d never seen before (telephone message, sunset, etc.) so hopefully the curve will be really lenient. I did the CB blue book test yesterday and got 67 raw, but on today’s test I skipped 9 and probably got more wrong -_-</p>
<p>Was the question asking about magnetic field or force, sorry I forgot. Is the telephone one due to total internal reflection?</p>
<p>fairly certain it was magnetic field.</p>
<p>Lenient; Around 59 raw for 800.</p>
<p>About the question asking to find the force on a charge moving in a magnetic field
I think the force is zero because the angle between the velocity and the field is 180, so sin180 = 0</p>
<p>Did anyone get a table with time periods in the left column, and distances in the right? I think both questions were pretty hard.</p>
<p>yeah I’m pretty sure the force on the proton was zero, also because right have rule doesn’t work.
did anyone get what is always changing when an object has an unbalanced force?</p>
<p>I think I put momentum</p>
<p>anyone want to put an answer list together? I’ll do it later tonight when I’m home if no one does.</p>
<p>Giggsy, ill be highly grateful if you do!</p>
