<p>no but if the two blocks are at the same temperature..</p>
<p>oh damn... i thought the 5kg block would be NATURALLY bigger than the 2kg one, and thus it would have more heat!! (since the one with more volume has more heat if they're at the same temp) </p>
<p>you're right, mass doesnt have anything to do with this...</p>
<p>For the one about the beta decay, about why its momentum isnt constant, was it because a particle is emitted? I know the atomic number changes, but I don't see what that has to do with anything</p>
<p>wat do u thnk the curve will be this time..??</p>
<p>Degeneration: You are correct. A neutrino particle is released in a beta decay.</p>
<p>wat is the answer of the block question.??
isnt it that heat transfers only from hotter to colder and mass doesnt have any part in it??</p>
<p>....read above.</p>
<p>ehhh... the previous posts confused me alot..</p>
<p>thnkx</p>
<p>yeppy +1!!</p>
<p>Anyone remember the question with wires of different thickness connected in series. I believe it was constant current.</p>
<p>The smaller the cross section of the wire, the higher the resistance.</p>
<p>the higher the resistence, the lower the current .. isnt it??</p>
<p>i screwed up on the current question too, the current doesn't change because the resistors were in series. </p>
<p>does anyone remember the answer for the first three questions which compares the values of the two columns?
what about the acceleration of the car from that table...i put the acceleration was closest to 1.0 m/s^2, not sure if that was right?
doesn't turning off the current and moving a magnet through the coil induce an emf?</p>
<p>im pretty sure the acceleration of teh car was 1.3 b/c each succesive second the distance travelled in creased by about 1.3 meters. and wow I feel stupid about the different resistance of the wires with the current one. I totally overlooked that it was in series.</p>
<p>I got so lucky on that current question (with the resistors in series). I realized the current was equal right at the very end, and fortunately had time to change it.</p>
<p>The resistances are different but the current stays the same. :)</p>
<p>Yep. I had originally put it down as different, before changing it.</p>
<p>ohhh noo.. there goes another -1 :-(</p>
<p>What did everyone put for the electric shock question? (girl is getting out of a car, what least affects the electric shock she would get?)
Options were:
-Running car engine
-Distance she slides
-Humidity
-Clothes she wore
-Surface of the car</p>
<p>yeh... wat was the answer 2 that???</p>
<p>whether the engine was on or off, i think?</p>
<p>Damn. I guessed distance she slides.</p>
