<p>How is energy conserved? Isn’t mass technically being converted to energy… </p>
<p>No…it was E=hf not E=mc^2</p>
<p>Energy is always conserved. Also I put internal and electrostatic.</p>
<p>Also i got a different momentum one for momentum of the system or whatever i got 116.something not 7.whatever</p>
<p>I faaaaaaaaaaailed. Bad.</p>
<p>Would matter be accepted (law of conservation of matter)? </p>
<p>It was 7.38. M1V1 + M2V2 = Pt</p>
<p>(7.28)(8.5)+(5.45)(10)=116.38kgm/s</p>
<p>i put mass and momentum is that okay?</p>
<p>So mass would be incorrect? </p>
<p>Would mass be accepted?</p>
<p>Mass if fine</p>
<p>You have to subtract it because it’s moving in the opposite direction </p>
<p>Oh now i understand</p>
<p>damn i got like 6 points off already</p>
<p>Was the which would emit a photon of visible light, 5-2?</p>
<p>Does anybody remember what they put for the question with the electron, does it produce a magnetic or electric field? Or both</p>
<p>BTW, curve is better this year than past years… </p>
<p>@jamesjunkers yeah i put 5-2</p>
<p>I honestly didnt know for that last one so I figured mass. And I put inertia even though it’s the same thing as mass. -flips hair- I’ll take my 55 with pride.</p>
