Current atomic theory
Fascinating reading... I am not at the same educational level (yet) as the rest of you. I am currently an undergrad in college. I find this fascinating. So I pose this question... knowing that the Bohr model is the current standard primarily used, what data has been...
Question, is CDM only a theory or is it proven and measurable? Had a hot debate with someone about this the other night... same question with black holes, are black holes proven? It was my understanding they aren't, b'c even if we sent a probe or something of the like into to gain measurement...
I haven't taken physics in my college curriculum yet, so could someone help me understand why when slamming the brakes on my car, the weight of my car isn't a factor in the "slide to stop" time? Assuming I am not pulling weight behind me (trailor or something) and I have no collision with...
The professor has us using the falling body formula=- 1/2 32ft/s^2 + Init.Velocity + Init. Height(y intercept) That's why the -16 is there. I have narrowed down the problem I am having... its the initial velocity. Since I have been instructed to not take into account the horizontal movement of...
I have been trying to figure this out for 2 weeks.
A helicopter is begins its horizontal motion 2500 ft from the center of a targe 30 ft above the target traveling at 40mph. The target ( a pile of boxes) is stacked 15 ft high off the ground. At the appropriate time, a person is to jump out...
