Here's the problem...unfortunately I don't remember much about orbital motion. I'm a bit stuck on where to begin. If somebody could give me a little advice on how to tackle this problem I would appreciate it. Recall that the magnetic force on a charge q moving with velocity v in a magnetic...

The wikipedia entry on strange matter didn't tell me all I wanted to know, so I'll have to ask here: Is strange matter a fluid like 'neutronium' matter is? i.e. given advanced enough technology, could a cube or other non-spherical shape of strange matter be created? Or would it form a sphere...

Hi everyone, My latest acquisition is an 8"-dobsonian mounted telescope, and I thought I'd try a bit of asteroid observing. What I would like to do is record the asteroid's position over the course of several observations and as a mathematical exercise, calculate its orbit. I know how to use to...

orbit n orbital! hi, what is the difference between Orbit and Orbital? when electron is moving so fast, how can we assume of arranging them in an arbital? I am unable to get the actual concept!

this is the expression ofr the orbital period T= 2*pi*R^(3/2)/sqrt(G*M) that i found now the next question asks me to find an expression for T^2=?

Can anyone give me a clear and good explanation of Newtons Law of Gravitation, Keplers Law & Orbital Motion.

A communications satellite is in a circular orbit around Earth at radius R and velocity v. A rocket accidently fires quite suddenly, giving the satellite an outward radial velocity v in addition to its original velocity. a) Calculate the ratio of the new energy to the old and new angular...

Is there a resource showing relative distances between the planets charted for different times of the year? Specifically, I'm looking for tables or software where I can type in a date, and a starting location, say Mars, and see the distance to a selected body in the solar system, say Jupiter...

1. A proton of mass rotates with an angular speed of 2*10^6 rad/s in a circle of radius 0.8m in a cyclotron. What is the orbital angular momentum of the proton? 2.An object's angular momentum changes by 10Kgm/s^2. What magnitude average torque acted on this object? 3. A pulsar which emits...

I need to find the orbital radius of a satilite, while only knowing its orbital period. i tried.. a = 4π²r/T² Fnet = Fg a = Gm/r² Gm/r² = 4π²r/T² r = cuberoot(T²Gm/4π²) didnt work out..

Came across another question during my exam review. Seems to me like there is insufficient data again. When the space shuttle delivers a crew to the international space station, it usually boosts the orbit of the station from about 320 km to 350 km. How much energy does the shuttle add to the...

Im having a little trouble finding the orbital period of Earth using: t_{years}=2\pi\sqrt{\frac{a^3}{GM}} "M" being the mass of the central body, obviously the sun, at 2 x 10^30 kg "a" being the semi-major distance in Au = 1 So, \approx...

What path do electrons actually take in an orbital... If electrons are found somewhere within an orbital, what kind of path do they travel within it? ie- is it similar to the orbits of the planets or more random like? Thanks. :smile:

Yo, I don't understand the concept of the M.O. Theory and I don't know how to draw these diagrams. Are these closely related to Hybridization drawings and resonance structures? Please help me, I'm confused with all the bonding/anti bonding symbols etc. Thank you,

im not getting this problem AT ALL: You are an astronaut in the space shuttle pursuing a satellite in need of repair. You find yourself in a circular orbit of the same radius as the satellite, but 30.7 km behind it. How long will it take to reach the satellite if you reduce your orbital...

How do you determine the symmetry of the orbitals and whether they overlap in a molecular orbital diagram?

The orbital period of Comet Halley is calculated to be 75.5 years. Many other comets have orbits that extend much farther from the sun, and hence have much longer periods. At aphelion, a typical long-period comet is about 8*10^12 km from the sun; at perihelion, it passes inside the Earth's...

Alright, I have a question regarding quantum physics, but I don't want to post in that forum, because it scares me. I saw a website, it had an atom fill up electrons in orbital, as it got high, a rather unusual thing happened, an electron from an S orbital jumped to fill a P sub-orbital. I was...

Hi guys and gals I have been given this question and have spent so far around 4 hours pondering calculating researching and reading and have got no where except into a large state of confusion! Its probably really really simple but i just can't seem to get logical answers and now i have...

The nucleus of Tungsten conssits of 74protons and 110 neutrons. SUppose all of the electrons were stripped off, but one, leaving a W+73 atom. Using the Bohr idea of the atom (not anything else!) How much energy nrequired to remove this last electron from orbit?? The energy of the elctron...

The Earth has an orbit of radius 148 million km around the sun. What is the speed of the Earth on this orbit? dont know how to do it i have used a couple of different formulas and haven't gotten it right can anyone help?

I'm just curious as to why, when an orbiting body loses velocity (slows down) it's orbit must become more shallow, or smaller. I know this can be explained logically, but I would appreciate if someone could prove mathematically that it should happen. Thanks.

somebody help me start this question The asteroid belt circles the sun between the orbits of Mars and Jupiter. One asteroid has a period of 5 Earth years. What is the asteroid's orbital radius and speed? Thanks!

Can there exist a satellite which shares orbital foci with our Sun, and with the extrasolar likes of (e. g.) the Oort cloud - but in particular another star, say Proxima Centuri?

Show that the escape speed from a planet is related to the speed of a circulat orbit just above the surface of the planet by Ve = square root(2Vc), where Vc is the speed of an object in the circular orbit. I'm looking at GMem(object)/r^2 = m(o)v^2/r But I do not know if this equation will...

When looking at the orbital names, why does the fourth period of elements go 4s, 3d, 4p? Why is it 3d? Why not 4d?

Is anyone familiar with "Satellite Orbits: Models, Methods, Applications" by Montenbruck and Gill? I'm looking for something that starts a little more basic, but builds up to a decent level. I have my own copy of Vallado's Fundamentals of Astrodynamics and Applications, but it's a little...

http://www.medphys.ucl.ac.uk/~martins/orbit/orbit.html One of the best programs for anyone interested in orbital mechanics of space flight or anyone who just wants to simulate a shuttle or Apollo flight with a joystick. :smile: I found this a couple of days ago and have downloaded about...

When an electron is orbiting a proton, why is it not compelled to be attracted to the proton? Why doesn't it stick to the proton?

Th eother day while surfing I found a list of the 120 detected extra-solar planets. (Minus the 2 super giants) Just for the heck of it I decided to take this info and plot to a graph. I decided to plot planet mass against oribtal distance. The graph is attached. I also plotted the...

I am a first-year physics/chemistry major in First-term Calculus-based Physics. Normally, I have no trouble with my physics assignments, but this problem...man, i have no idea even where to start, even after analyzing it for two hours straight! Any help would be appreciated! 5. You are an...

Can we discern any movement by the microwave background perpendicular to its expansion?

What would the value of linear momentum in the r direction for an electron in the 1s orbital of Hydrogen be? Is this an expectation value or eigenvalue?

A comet is first observed at a distance of 1/3 AU from the Sun and traveling at a speed of twice the Earth' s orbital speed. Assuming that the Earth' s orbit is circular, argue from an energy viewpoint whether the comet' s orbit is elliptic, parabolic or hyperbolic. Now, I know the...

I have produced the most accurate electron binding energy equation known to-date. This equation predicts the ls orbital electron binding energies from lithium to uranium to within an accuracy of +/- 5%. The averaged error for all the ls orbital binding energies from lithium to uranium is only...

I am wondering what forces cause the nodes between orbitals to occur, and if these nodes are ever penetrated or crossed by electrons during exitation of the atom.

Have you guys heard of this: http://www.sciam.com/article.cfm?chanID=sa006&colID=5&articleID=0001A73A-45BC-1F7F-82D883414B7F0000
