I am having a tough time with getting my heard around what Ksp is; this question isbugging the heck out of me: Q: Calculate the Ksp of Thallium(1) Chloride at 100 Degrease celcius. The concentration of saturated solution of salt at this temperature is 2.4g / 100 ml . Me: As far as i...

Can somebody help me out with this?? Calculate the no. of degrees of freedom of 10 cc oxygen gas at Normal temperature and pressure. This problem is from the kinetic theory of gases chapter.

How well does the following represent an ordering for degrees of consciousness? 1. Being 2. Sensation 3. Action 4. Observation 5. Interpretation 6. Intercommunication 7. Participation

A friend of mine just did some work for this person and brought him to my attention. He is certainly one of Oregon's finest. I guess his 160,000 acre ranch [about 30 miles by 5 miles] includes private snow skiing. :cry: He is quite an impressive person. http://www.pamplin.org/home.html...

IHow much is a degree and why there are 360 of the in a circle?

Assume the Earth is spherical. Relative to someone on the rotation axis, what is the linear speed of an object on the surface if the radius vector from the center of the Earth to the object makes an angle of 62.0 degrees with the axis of rotation. Radius of the Earth = 6.37·103 km I know that...

I'm wondering if the nitrous oxide will totally dissolve at temperature of 350'C?

1. Calculate the rms speeds at 20 degrees celcius of atoms of helium (4u)? 2. The escapte speed from the surface of the Earth is 11.2 km/s. Find at what temp. the following gas (O2) have this value as the rms speed? 3. One mole of an ideal monatomic gas is heated from 0 degrees celcius...

The theory of quantum fields is very strange, indeed, I must admit. Usually in books they introduce a quantum field from the standpoint of a vibrating string in one dimension. Along the string are discrete points or masses that when one of which are disturbed a disturbance is created along the...

this should be a simple question, but I am just not getting the right answer. I need to change 25 degrees to radians. I know, that 360 degrees = 2pi radians, but I am not getting the right answer. thanks for the help

Consider a situation where a friend have a red laser or a torchlight shining across the room. And you are standing at the side, perpendicular to the light beam. If light traverse in a straight line, why is that you can see the light shining across the room when you know that the light that comes...

Ok, degrees measured in a circle are measured from the center, the inside. A square's, for example, is not measured from the center; if this were the case, all polygons would be 360 degrees. Polygons are measured from the points at which lines intersect, making the degrees given to a circle, and...

I was discussing with my friends that problem: If we have a cone, upside down, rotating with angular speed constant, how much degrees of freedom, the system has? Ok, I think that if the movement is restricted to rotate around a static axis, and the speed of rotation is constant, you don't...

A ray of light strikes an interface between materials 1 and 2 and enters the new material(2). The angle of incidence is 40 degrees. The index in material 2 is 1.5 times that of material 1. The refraction angle is ( in degrees):

Can't quite figure out how to start this problem. If Earth's radius is 6378 km and has a period of 24 hrs. find: a) centripetal acceleration of a particle at the equator. I did this and got 0.03 m/s^2, but I can't figure out how to start the second part. b) the centripetal...

Can anyone help me solve the following question: A particle is moving vertically at 4.8 m/s and accelerating horizontally from rest at 1.7 m/s2. At what time will the particle be traveling at 32 degrees with respect to the horizontal? I have got various answers such as 0.894s, 0.44704s...

Does anyone have any thoughts about how I could measure temperatures up to 1200 degrees F? I could buy a pyrometer or piece one together with a thermocouple and multimeter, but just wondering if there is an easier way to do it. Thanks, Jeremy

When considering the three dimensions of space and our freedom of movement in that space, does our ability to change our state of motion (acceleration) imply an existence of a fourth dimension, ie. four space-time dimensions? Given three dimensions each mutually perpendicular, we can move...

I know this is an easy problem, but I need to know 3 sets of polar coordinates for the Cartesian coordinates (-4,4\sqrt{3}}) So I graphed the points and got the hypotenuse, r = 8. How do I convert 4\sqrt{3}}) to degrees? (4\sqrt{3}}) = 6.92820 Is this in radians...

If you were to introduce diphosphate and oxygen to one another at apporx 40 degrees celcius, would they combust instantaneously?

I find it interesting how the Earth tilts only a few degrees and the weather changes so dramatically. Question: How far fetched would it be to think that the Earths weather system remains a stationary shell and the Earth simply rotates underneath it. To put it another way, the weather "shell"...

[SOLVED] Grads Vs Degrees Knew a civil engineer whose soecialty was hydroelectric dams. He used 400 grads exclusively - as opposed to 360 degrees. Would like to know the rationale behind this...please!

This hypothesis basically states that any 2 people on Earth are connected by no more than six levels of acquaintances.

The problem states: Travelers reset their watches only when the time change is 1.0 h. How far, on avg, must you travel in degrees of longitude until your watch must be reset by 1.0 h. I don't really understand what this question is asking for, but I attempted to "solve" this by keeping in...

A square has 360 degrees, if you measure the degrees on the outside, what degree do you get?

A temp change of 20 degrees C corresponds to a temp change of 68degrees F i got this one wrong? what's up with that?

My calculator has a conversion table for degrees Rankin and I had no idea what they are used for. Anyone know?

Why the angle of attack is 40 degrees for shuttle started to reentry I'm a newbie here.:wink: Because I am doing an assignment on the Columbia Shuttle Disaster. I need some data for supporting my statement. The shuttle must then tilt upward to present its flat bottom, covered with...

I am on schedule to graduate with a B.S. in Physics after Fall semester 2003. It will have taken 3 years and one semester from start to finish, and it dawned on me over spring break that I might supplement the physics with computer or electrical engineering. So I calculated it out and it will...
