<p>Reflected angle should have been equal to incident angle, and the refracted ray should’ve bent away from the normal.</p>
<p>@DAIMYO Woo got it right then, thanks!</p>
<p>@DAIMYO for 47 I got 3 …</p>
<p>It had to be the 8x8 vectors.</p>
<p>Air bag question? I put it decreases the distance of which the force occurs or something, anyone else?</p>
<p>For the question where you had to draw the vector I was dumb and put 1 cm=1 m instead of 10 but I drew my vector correctly. However when they asked for the magnitude of the resultant I put 10m knead of 100m. Will they still give me a point if I went by my conversion?</p>
<p>air bag question was an impulse question. J=F*t. the time is increased so it lessens the force
and how come for the arrow on the wave question it wasn’t an vertical DOWN arrow? cuz it was traveling right so that point would initially move downward</p>
<p>and 35 I put 4. it was 180 out of phase. I said d and h because they were the only ones 180 degrees (Pi radians) away, if u look at it like a sine graph</p>
<p>im pretty sure the answer was ONLY electric because i think a magnetic field is only induced if the particle is accelerating. but all electric charges produce an electric field</p>
<p>@maxweissman I put points A and C for that question (choice 1 I think) because one full wave is 360 degrees.</p>
<p>The open ended questions were really easy, I was suprised :0 pretty sure i failed the MC though </p>
<p>what was the answer to the question that asked how many joules was lost to internal energy when they gave you the kinetic energy was .02 joules???</p>
<p>@bankofyizmerica yep,that’s what i put. pretty sure that’s it</p>
<p>@rdward96 well that was what was given in the problem but i was stuck between .22 joules or 220 j even though 220 doesnt really make any sense haha i put .22 though</p>
<p>For the last question would charge and mass be accepted? Like charge regarding to the electron? </p>
<p>In the question regarding Charon’s accel. magnitude, how did you get a velocity to put into the centripital acceleration formula? I used the Fg value from the previous question as my centripital force and solved for velocity Did anyone else do that?</p>
<p>@bankofyizmerica Wait, really? I was pretty sure .02 was an answer, that’s what I put haha</p>
<p>@rdward96 yeah it was but i didnt know how to do the question like i found the potential energy and subtracted it with the kinetic and the difference was .20 joules so i just put .22 bc it was the closest i have no idea though</p>
<p>i got .02 as my answer too. i converted the mass into kilograms. i noticed that a lot of the b1 questions make you convert.</p>
<p>The answers is .02 </p>
