<p>1 is greater than 2.</p>
<p>F = MA</p>
<p>If Mass increases than acceleration decreases.</p>
<p>can someone explain to me the bicycle question? or like anyone rememberit?</p>
<p>bicycle question was saying : a person rides his bike north and the wind is coming from east . in what direction moves the flag ?
IMO since the guy rides north the flag points the south and with the wind coming from east the flag moves the same as the wind , that means toward west .</p>
<p>Ahhh, so what was the ellipse thing about the satellite and the sun? Was acceleration toward the center or toward the sun? Damn, I put the center.</p>
<p>Also what about the one where two equivalent masses were on both ends of a string, and there was some gadget measuring the tension of the string?</p>
<p>I thought the acceleration pointed toward the planet and that the tension ends up cancelling to 0.</p>
<p>For the equivalent masses one, it definitely wasn't 0. Think about it. If the Incredible Hulk and Superman pull with equal strength on opposites sides of a spring, does the spring experience 0 N of force? I put 10 N because the forces are equal so I thought of it like hooking a spring up to a wall and pulling at it with 10 N of force. The wall exerts an equal force but the spring reads 10 N. But with that said I'm still not 100% sure about that logic but it's definitely either 20 N or 10 N and I'm fairly sure it's 10.</p>
<p>No... think about how a spring scale works. Envision the needle connected to the center of the spring... with the same 10N on both sides, th center of the spring doesn't move. 0 = balanced, which it was.</p>
<p>But there's tension on both sides of the string, pulling in opposite directions, so wouldn't you just add the two tensions together...?</p>
<p>it's 10N of force, right? Isn't force a vector quantity? So it should cancel...</p>
<p>20N. the weight is the weight whether its on opposite sides or not</p>
<p>it's 20 N guys.</p>
<p>If it wasn't weight and there were two forces acting on each other like this;</p>
<p>10N ===== <<scale>> ===== 10N</scale></p>
<p>Then the scale would measure 0 newtons.</p>
<p>i put 0.,..</p>
<p>It would show 10 N, since the pulley (frictionless) can change the direction of tension thereby 'canceling' the other 10 N block, leaving just 10 N. </p>
<p>A normal pulley problem.</p>
<p>they cancel out.................................. The answer is 0 for christ's sake</p>
<p>So we can all agree that it is DEFINITELY either 0, 10 or 20. Nice collaboration here guys.</p>
<p>Sometimes, it takes extreme reasoning to clarify a simple problem:</p>
<p>Imagine Earth and Mars tied on a pulley to a scale, could you just lift up the system at will - throw it around? Of course not. It has to have some weight.</p>
<p>You were supposed to bubble all 3, different brands make different spring scales. If it was a dual callibration scale it would have been 10, if it was a single TruScale scale it would have been 0. If you got the CVS brand it might have been 20</p>
<p>Earth and Mars dont have the same weight. And thats not the question. No one is denying that there is weight. Its what the scale reads.<br>
If you have a scale that you stand on and someone pushes the bottom of the scale with equal force, it would show 0 correct?</p>
<p>oh NO, i put 0 ... please someone confirm the right answer??</p>
