I don't have a specific problem I'm trying to solve, I'm trying relate all the concepts for basic thermodynamics. I'm not entirely sure where I am misunderstanding
1. What is work
2. What is internal energy?
3. What is heat?
4. What is enthalpy?
5. What is entropy?

I've been doing that, but "phys 22" vs "phys 2B" vs "Phys 22b" Doesn't tell me anything useful. I've been going through and googling "Class (phys 22) @ University (X)" one at a time and that's working though.
So far I see that it's pretty much

I want to teach myself physics and math -
I'm currently halfway through my first year in physics, but I hate riding the magic gravy train where my professors spoon feed me little bits of information - where there's some stuff I won't see for a year or two even though physics isn't necessarily...
The answer is 2.8N - I'm trying to match my answer to that one.
But I don't really understand what you mean.
Do you mean just line one of the sides with an axis?
(Triangle)
Me
M mS
So that there is no Xdir force from Me?
OH, sorry.
Find the magnitude of the net gravitational force exerted on the spacecraft by the Earth and moon. - edited it it in the first post too
edit: also that it's not 3.84×105km - it's 3.84 x 10^5km
edit: in the image I accidentally dropped the squares around [[ROOT][Cos60(Me - Mm)^2...

In 1993 the radius of Hurricane Emily was about 350 km. The wind speed near the center ("eye") of the hurricane, whose radius was about 30 km, reached about 200 km/h. As air swirled in from the rim of the hurricane toward the eye, its angular momentum remained roughly...
Can you elaborate on what classical ideas are? Are they Newtonian ideas?
Basically, what you're saying is that it behaves as it is described with mathematics and that it's impossible to try to visualize it with classical ideas, meaning it won't be comprehended ever?
I'm just trying to...
With the double slit experiment, instead of firing one electron at a time, I assume you would get the same outcome if you fired one photon at a time?
I was thinking that maybe an electron isn't just sometimes a wave, sometimes a particle: I think that the wave property is reflective of...
I have two points I'm thinking about here...
1. What is intelligence? .. If a person is said to be more intelligent than another, does he have more gray matter? Are neurons organized in a different arrangement allowing for more efficient thinking; a more efficient pattern of application of...
