Atmospheric Definition and 261 Threads

This is a problem i have in my homework and i want to learn how to do these and get them right so please don't just give me an answer lol The desity of the fluid in a tube is 850 kg/m cubic. THe pressure exerted by the atmospher is 1.013x10^5 Pa. What is the pressure P in the container...

Can someone explain the equation g/cm^3 in layman's term? I was reading up on this article on Saturn's moon Enceladus, having heat, and the first thing i though was the gravitational tuggin from Saturn and it's other moons. And i came across this equation and seem like it's used to base density...

More emphasis... I understnad that atompsheric pressure affects boiling point and that as atmospheric pressure increases, boiling point increases...but why?

What factors determine the pressure of a planet's atmosphere? For example: Mars has an atmospheric pressure that's much lower than Earth's. Well, o.k., that's a simplistic statement. Go high enough up in Earth's atmosphere and no doubt you can find a spot where the "atmospheric pressure" is...

I'm sure this has been asked uncountable times before. How can any tree be more than 32 feet tall?

I always wondered :confused: When you are standing on an open area. the pressure exerted by atmosphere on your head is the total weight of the atmosphere column just above your head.Of course, divided by the area of your head. When you are inside a closed room! Even then the atmospheric...

Do photons travel at the speed of light (c) inside the Earth's atomphere? Or is friction a factor of their velocity. Ty

I was a bit surprised to find that the average recorded atmospheric pressures at such locations as Mexico City (2.2 km above sea level) are roughly equivalent to those *at* sea level, i.e. in the 99-102 kPa range. I find this a bit odd, since the air density at this location is just under 80%...

This question is giving me some difficulty. Under normal atmospheric conditions, the potential in the atmosphere near the Earth's surface rises 80 V for every metre of increased elevation. A) What direction will free electrons in the atmosphere move? B) Calculate the loss in electric...

Anyone have a link or direct info regarding the rate at which the Earth's atmosphere dissipates into space? I'm looking for both an estimate of the current rate as well as a model (time and mass dependencies). Thanks.

it is not a myth that on some days our hair seems to not want to cooperate with whatever style we've chosen (this is especially true for women's hair styles). meteorologists use an instrument known as a hair hygrometer to measure the humidity in the atmosphere, because human hair has been found...
