Isn't that idealized...? I think that would only work in a universe that did not have a dark matter component.- sharpnova

I highly doubt that. I'm just a kid and I'm not that into science and definitely not very good at it. But thank you anyway, Nidum.- sharpnova

Force = the derivative of momentum with respect to time Which of course as any school child knows, falls apart completely due to dark matter.- sharpnova

Not getting right answer in force problem
I also tried it with the standard interpolating function: (1 + x^2) ^ (-1/2) and still got an answer that is slightly different from the book's.- sharpnova

I would assume his law about force which is incorrect but was corrected in 1983. The teacher (10th grade) hasn't done a very good job of teaching. His method is to give us problems and ask us to research how to find the answer. I researched force and read about the correct model for Newtonian...- sharpnova

Milgrom's law? I am using the simplest interpolating function and the generally agreed upon acceleration constant.- sharpnova

Not getting right answer in force problem
Homework Statement A 100 kg object is accelerated by a force of 10,000 N. What is the acceleration of the object caused by the force? Homework Equations F_N = m * u(a / a_0) * a a_0 = 1.2 * 10^-8 cm / s^2 The Attempt at a Solution I'm using u(a / a_0) = 1 / (1 + a_0 / a) as my interpolating...- sharpnova

Graduate Did the LUX Dark Matter Experiment Fail to Detect Dark Matter?
For you to make such a statement implies that you have a deep understanding of how dark matter works. Please expand on that. -

Pressure Cooker Internal Energy Problem
Homework Statement A pressure cooker is a nearly air tight sealed system. When seated on a stove burner and heated, water turns to steam and increases the pressure inside, resulting in higher temperatures so food cooks faster. Suppose 1/2 cup of water is inside the pressure cooker and it is on...- sharpnova

Impact of container on final temperature of system
I believe it would then reduce the final temperature of the system since it would have a resistance to temperature increase that would suck up some of the thermal energy (and started at a lower temperature than the system's average at the start) Assuming I have that right I think I understand...- sharpnova

Impact of container on final temperature of system
Sorry I wasn't clear. When I said that "I was thinking the 'no heat enters or leaves' was just a magical constraint" I was saying that I thought that a somewhat nonsensical constraint had been placed on the system in order to simplify the problem. I assume by emphasizing that the constraint was...- sharpnova

Impact of container on final temperature of system
I'm guessing that means it starts at 0 degrees Celsius but I don't understand why. I was thinking the "no heat enters or leaves" was just a magical constraint because if the container was cooler than room temperature then it should be bringing heat into the system... or if it's warmer then it...- sharpnova
