<p>why is it unchanged?</p>
<p>Is F= (G<em>m1</em>m2)/d^2</p>
<p>so as the mass inc, force inc?</p>

<p>this one is total Chinese to me</p>
<p>and btw,</p>
<p>what does “zero rest mass” mean?</p>
<p>photons have zero mass cuz they are radioactive atoms no?</p>

<p>this has to do with torque right? but how to use the rules?</p>
<p>the one i know is torque= force*lever arm</p>

<p>I know this one is because of constructive and destructive interference, but what causes this interference?!</p>

<p>Isn’t momentum always conserved. Why isn’t III correct then?</p>

<p>Will such a question even come up in the actual thing. I’m beginning to think my teacher just came up with these questions really.</p>
<p>Never have I ever run into “Line Spectra” while studying from Barron’s.</p>
<p>I googled it, but never really understood!</p>

<p>the correct ans is supposed to be “a”, but shouldn’t the photon’s speed dec as an aftermath of the collision?!</p>

<p>so you only induce a current by “inc” or “dec” i or the electric field etc…?</p>
<p>The can’t be constant</p>

<p>73) I don’t know how to get it</p>
<p>74) Is she trying to say that the force is constant, so as m decreases by 0.5, acc increases by a factor of 2?!</p>

<p>HOW DO WE CALCULATE THAT?</p>

<p>I think we’ve established the fact that I dunno how to get “h” of a simple pendulum.</p>
