<p>So far 3 wrong 1 omit. How r ur scores going?</p>
<p>What was the answer to the work done in the pressure vs volume problem. I think I said it absorbed everything but red light(maybe$</p>
<p>sometimes only 59points will be 800,but sometimes 66 will be 800</p>
<p>What about how would you change theta/vo for maximum distance and max time</p>
<p>for the theta/vo one, i put increase the velocity but keep the same angle for max dist and max time</p>
<p>somewhere between 3-7 wrong so far, 2 omitted</p>
<p>what did you guys put for the one which the mass attached to the string on the pulley with the spring scale that weighted .2 kg and read as 1 N?
the choices were:
.8 kg
1 kg
1.2 kg
then two others that were def wrong</p>
<p>So, I definitely got 4 wrong, and I omitted 1. What score do you guys think I’ll get?</p>
<p>800 10char</p>
<p>Are you sure? I heard somewhere that what people say about -16 being 800 isn’t true. And it was more like, -3 being 800. ._.</p>
<p>Haha no way. Physics has a HUGE curve. </p>
<p>Is the theta vo for the soccer ball one? Because I put that vo increases but angle stays constant.</p>
<p>Does anyone remember the one question about being in a dark room, and which object you’d be able to see? I guessed the heated wire, but I wasn’t sure…it probably was really easy</p>
<p>^^ thats what I said</p>
<p>tungsten wire was correct - it illuminates with white light</p>
<p>Tungsten is the wire used in lightbulbs so if it’s heated to over 1000 degrees… Yeah it’s gonna light up.</p>
<p>Yeah, that question was weird… I just felt that none of the other answers made sense.</p>
<p>Anyone remember the answer to the one with the mass hanging off a pulley with a 0.2kg spring scale measuring 10 Newtons?</p>
<p>That was 1 kg. The weight of the scale doesn’t affect the measurement.</p>
<p>Even if the scale was appended to the wall with the string? The question didnt specify</p>
<p>Yeah, the scale only measures the force applied to it’s hook thingy (technical term, btw), which is the tension. In this case, the tension equaled the weight of the block.</p>
