<p>oh and for the 6V, i jsut said that was right bc it told you the voltage different across the battery was 6V and it was parallel to the rest of the picture, but yeah i still got 6V, just in different ways</p>
<p>ya, i got 2v for the one about period and g increasing.</p>
<p>and for the cross-product one, i got 90* too.</p>
<p>no i think this was a uestion regarding some spring and equlibrium position</p>
<p>i mean it wasn’t hard bc of the material, it was just how it was tested, very time consuming. I finished with only 2 minutes left, and usually i finish earlier than that. I think it was a fair test though</p>
<p>i think i got root2v, because in a spring as the length goes up, v does also but radically because the equation is T=2pie times root l/g</p>
<p>and yeah the cross product was 90</p>
<p>also does anyone know the exactly answer to the man’s weight? and to the mechanical engergy vs momentum vs KE one?</p>
<p>The eave that was not possible? 0J or 110J</p>
<p>did any one get gravitational potentional as an answer to the question that asked what did not follow the relationship</p>
<p>basketball, i think it was something like T^2 (the variable might be something else,)
and the variable was doubled, so then it became 4T but after square-rooting it, the ratio ended up to be 2 times greater. so i got 2v.</p>
<p>did any one get gravitational potentional as an answer to the question that asked what did not follow the relationship?</p>
<p>i put the one that had x ~ 1/r i think it was electrical potential one. all the others (Fg, Fb, light and sound intensity) had x ~ 1/r^2 relationship.</p>
<p>i’m not sure then, i don’t remember this question really. can whoever ask it be a little bit clearer?</p>
<p>i chose momentum only for that one.</p>
<p>I’m pretty sure the satelite one was the other two and NOT angular momentum.</p>
<p>Angular momentum is directly proportinal the the radius, and the radius changes in an elliptical path.</p>
<p>at laure327. was that choice E? bc then yeah i definitely put that, cause the equation for electrical potential energy is kq/r.</p>
<p>at Blackroses216. Angular momentum is proportional to mass x velocity x distance. Mass stays the same and yes distance does get smaller, but velocity then increases as the radius gets smaller. So i think angular velocity stays the same.</p>

<p>well, the others were potential energy and something else, and i think they are wrong</p>
<p>does anybody remember the thermal physics problem, with a graph and lines marked A, B, C, and D. not sure what it asked, but it was pretty challenging i remembered</p>
<p>“does anybody remember the thermal physics problem, with a graph and lines marked A, B, C, and D. not sure what it asked, but it was pretty challenging i remembered”</p>
<p>It was something like, during time 1 and 3 the temperature didnt change and during time 2 and 4 something else…idk</p>
<p>I said that the temperature after going through the entire process was the same, but I wasn’t sure.</p>
<p>i got “at the end of interval A” for a question</p>
<p>the other one was acceleration… the acceleration of gravity is a constant, therefore it stays the same? and there was no answer for just II, it was I and II so i put that. :/</p>
<p>If what basketball1 said about the velocity increasing, then idk. 
whatever, it’s done with! haha</p>
