<p>dont remember.. sorry..</p>
<p>EDIT: oh wait... wasnt that just D/T = 6km/3hr = 2km/hr?</p>
<p>hmmmm i think it was something like.. the guy travels 6 km(figure not correct) in 0.5 hours (correct) and then travels 15 km(figure not correct) in the next 3 hours (correct). What's the guy's average speed...</p>
<p>I think the total time taken = 3 hours. And the distance was 6 km.. Hence= 2 km/hr</p>
<p>yea, it mightve been... lol that was dumb.</p>
<p>for some reason, I thought that question was too easy and good to be true... I wonder if anyone else can confirm if 2 km/hr is the answer?</p>
<p>b/w was there a consensus reached on the current flowing up questiion?</p>
<p>which one was that?</p>
<p>I got some questions that need some answers
if u wanna give answers type number and then the answer</p>
<ol>
<li>For the transverse wave is said how far 2T which part was it on the wave?</li>
<li>Question about force ... i put something about one about radial and tangential force </li>
<li>Electromagnetic Radiation lowers energy?</li>
<li>F = root (Rf/m)</li>
<li>Convection/Radiation ?? or just Radiation light for light bulb</li>
<li>1000 MW 30% efficiency ?? question was like most waste material</li>
</ol>
<p>4) Your answer is correct</p>
<p>5= convection/radiation
6= Correct
I dont remember 1-3</p>
<p>do you remember the exact question for #4?</p>
<p>3) i think that's what i put
5) is ONLY radiation, the question specifically said that there is no air inside the insulated box
6) correct</p>
<p>yo, hugs for someone who is willing to compile the list of questions we have gone over.</p>
<ol>
<li><p>Its lyk atom emits electromagnetic radiation what happens ...
d was lyk electron jumps to higher level
e was total energy goes down</p></li>
<li><p>it was lyk whats velocity if planet is going around in a circle</p></li>
</ol>
<p>another question diffraction increases with:</p>
<p>increase in wavelength
increase in frequency
smaller slit length</p>
<p>o.o" I'm getting scared. Discuss more questions!! I need to see if I recognize which ones I answered incorrectly. Then I can estimate my score. I agree witih folon. Would be great if someone could compile all the questions we've gone over. XD</p>
<p>i remembered 70+ questions but too lazy to write it down i'll post them when i have time</p>

</p>
<p>I believe its I and III becase of [ dsin(Theta)=(Lambda)n ].. Also, Wavelength and Frequency are inversely proportional and both cant increase at same time.</p>

6. 1000 MW 30% efficiency ?? question was like most waste material
[/quote]
</p>
<p>I thought it was 900W 30% efficiency ( not sure if these figures are accurate but am pretty sure that the combination produced Work of 270J)</p>
<p>E=W/Qh<br>
W= (e)(Qh) = (900)(.30) = 270J</p>
<p>It was the option with the lowest amount of work produced which means higher amount of waste...</p>
<p>actually, the other option of 1000 * 70% = 630 joules of waste</p>
<p>Can someone compile everything we went over?
It is very confusing and a lot of people would like a list.</p>
