<p>@singgus i think so thats what i put bc it has greatest resultant that way</p>
<p>It has to be the same for both because that signifies a 45degree angle…
Then it is 8 for both (as opposed to 6) because Vix is geared… </p>
<p>Wait and I’m still unsure about the two flint rocks- electromagnetic and internal?</p>
<p>do you guys remember the question for the linear graph and it asked for the (power?) exerted at t=2s and t=4s. was the answer the same? i think that was question 50 and i remember putting the same (think that’s choice 1) but for some reason i stored (3) on my calculator.
now i’m thinking i bubbled wrong :(… i always think like this lol </p>
<p>@singgus I believe I put that it stays the same, because work and time were directly proportionate to each other</p>
<p>@singgus Yep it was the same, the power = the slope and the slope never changed.
Are we SURE that a moving electron doesn’t create a magnetic field? My teacher taught us how EM waves work and that’s because a moving electric field causes a perpendicular moving magnetic field which causes a moving perpendicular electric field and so on. This would be a moving electric field since the electron has velocity, so wouldn’t that cause a magnetic field?</p>
<p>@rdward96 i put electromagnetic and internal. do you remember what choice “the same” was?</p>
<p>@DAIMYO it kind of does. When you strike 2 objects, doesn’t some small mass gets converted into nuclear energy? IDK why I thought that but the spark and electrostatic is making more sense :L </p>
<p>@Kgman04 yeah idk i put both cuz i thought it just had to be a charged and moving particle to create a magnetic field </p>
<p>For the hydrogen emission causing visible light, what did you guys get?
I think I got 5->2</p>
<p>@singgus almost certain it was choice 1</p>
<p>A moving charged particle does create a magnetic field.</p>
<p>Also, for drawing the resultant in the short answer, you had to move one of the vectors first, right? </p>
<p>I put 6 and 6 for the two velocities because of the Law of Sines (6/ sin 45) = (radical 72 / sin 90 ) where rad 72 was the hypotenuse and 90 was the angle opposite it.</p>
<p>Also what was the answer to the elevator question? It was like if a 750N person is on an elevator accelerating downward, the normal force is… the choices were equal to 750, greater than 750, less than 750, or 0.</p>
<p>I said less than 750</p>
<p>I put less than 750 for that one</p>
<p>@rdward96 sorry just one more question… do you remember if that was that question 50?</p>
<p>@jamesjunkers i also put 5-2</p>
<p>I said less than 750.</p>
<p>Why is it no nuclear and internal??</p>
