<p>was the one with the least current the trial that had 880 as its resistance? my reasoning was a greater resistance would equate to less current (v/r)… i might be wrong</p>

<p>Elizabeth, I’m pretty sure it was Trial 5 or Student 5 or something.</p>

<p>What do you guys think a -3 and - 4 are in this test?</p>

<p>for the projectile motion where it asked would the maximum height of X on earths surface be higher or lower… it was lower because the force due to gravity is greater right?</p>

<p>by greater i mean a stronger force due to gravity</p>

<p>elizabeth12345, was that the first option?</p>

<p>it was the first or second i believe</p>

<p>any thoughts on the curve?</p>

<p>^ Yes it’s 2x4
You wanted to longest one with the smallest cross section.</p>

<p>What’d you guys get for the voltage problem that asked something like, “If the switch was in the off position, how much voltage went through?” The answers were like .000 v, .100v, .200v, etc. This might’ve been an easy question, but I didn’t really grasp the concept</p>

<p>yeah, i put that too. Im pretty sure it was mashed potatoes</p>

<p>Yea so I put lower @ Elizabeth. I put students 1 2 and 3 for mass constant because it said before each trial conducted that they are using a 5kg thing. Also what did students 1 and 2 differ on. Was it the plasmid being cut? Because each trial they cut a different plasmid.</p>

<p>wouldnt it be 1x4? that was the one with the smallest cross sectional area and length.</p>

<p>Was that the last option?</p>

<p>2&3 were constants!</p>

<p>I put 1x4 cause in the table I saw that the lower the cross section the higher the number</p>

<p>If the 1x4 was the last option, then it was the right answer.</p>

<p>Yuppie 2x4</p>

<p>I dont think 1x4 was even an option…</p>

<p>1x4 was an option and it was the correct answer based on the charts.</p>

<p>I got a 35 on the science on the June test and honestly this science test seemed A LOT harder to me. Then again we all have different brains, so maybe my brain just didn’t function very well on this passages.</p>
