thank you for pointing that out, I don't know what I was thinking in my reasoning that the volume would decrease. Perhaps I had just been used to doing something similar in previous questions I had been working on prior to trying this one. Nonetheless, wouldn't I set the problem up with delta...
I have tried this question 6 times (getting the same answer more than once) and am still not getting the correct answer. I think I need some help understanding where I'm going wrong.
The question: A container is filled to the brim with 1.35 L of mercury at 20°C. When the temperature of...
I calculated two different answers, both of which were to my dismay incorrect...but I am thinking that a conversion error might be the culprit. I am having trouble understanding what "a period of 25.3d" is -- as in, what does "d" stand for...should it be a time unit?
Could someone help me start this problem. My mind it in the angular momentum mode and I am having trouble seeing where to start on this one. :confused:
The sun's radius is 6.96E8m and it rotates with a period of 25.3d. Estimate the new period of rotation of the sun if it collapses with no...
I have calculated the moments of inertia for both the solid disk and the rod, but am getting stuck on how to solve for alpha in the torque equations so that I get acceleration. Can anyone shed some light on this question for me? I really appreciate it.
Here is the question I seem to be...
I seem to be stuck on this problem. I thought calculating the velocity of the center of mass of the system would get me somewhere, but I remain confused about where to go next. Here is the problem:
The light isotope, 5^Li is unstable and breaks up spontaneously into a proton (hydrogen nucleus)...
