What is the shape of snowball? i thought it's circle but my friend said it's a sphere.

I am asked to deduce the shape of a curve by knowing the following: The estimate of the definite integral for the area using the trapezium rule with 2 intervals of equal widths is above the real value. The estimate of the definite integral for the area using the trapezium rule with 4...

http://www.quixtar.com/ I saw that Amway now has a slick advertising campaign running on TV. I don't have the time to comment on this in detail right now, but I can say that I got involved in Amway when I was 18 years old. I had a downline of over 50 people, including one of the richest men...

What's the difference between "Electron Domain Geometry" and "Molecular Shape"? Please help! Thanks

i know how the magnetic field is shaped around a wire with current, and in the case of a solenoid, and in a bar magnet or U-magnet but that is the sum of all the magnetic fields of the charges moving through them. what i still don't know is the shape of the magnetic field surrounding a...

Assuming ray optics model is valid, what lens profile focuses light to a point? It must not be spherical, otherwise there would not be the term 'spherical abberation'.

i don't know how to describe the relationship between surface tension and the shape of a liquid drop. Also what are the attractive forces that increase surface tension?

I have a flow acting perpendicular to a shape ie an airfoil however i don't think an airofoil is the best shape for the flow not to recirculate too much was wondering if anyone has any ideas? please view my attachment for basic drawing of the problem thank you engineering

What are electromagnetic waves supposed to look like in 3D? Also, in the vacuum of space, electromagnetic waves are supposed to travel at light speed. Is this the linear speed? Or the speed of the flux as it curves?

I am interested in the theoretical shape(s) of black holes. I read that they may be cone shaped, they made be "shells", they may be two dimensional, etc. Can i get some clarification? thanks, jlr

Hi there, I am developing a really cool new product and it somehow relates to pressure's behavior. Since I do not have any Physics background I will appreciate if someone could help me out. The thing is that I attach a small container to certain area. This attachment actually seals the...

[FONT="Book Antiqua"][SIZE="3"] Hello, the question I have to answer is above in the Title...I thought that the V shape of the shock wave gets wider the faster you are going. No? Thanks Zach

Dear all: The question is like this: Given a point in a shape like square or triangle. Let's take square as the simplest one. Say the length of the side of the square is l. If add a noise to the point which will move the point [tex]r[\tex] distance and the direction is arbitrary, what will...

[SOLVED] spinning liquid creating a parabolic shape take a container of liquid and spin it... a parcel at any given radius (r) experiences (in the rotating frame) a force outward = mass x angular speed^2 x r and a vertical force of mg. Thus the surface curves such that the tangent to the...

I find in the literature the following transformation equations for the space-time coordinates x'=g(x-vt) t'=t/g g=gamma. Please tell me what do they bring new in the approach to SRT? Thanks

If not, then what are the conditions for us to construct a periodic boundary condition(PBC)? If so, then please help me construct a PBC for the lattice shape in the attachments. I want to ask that what lattice site m's left neighbor is and what lattice site i's down neighbor is.From the...

Hi all. I am taking a course in mechanical vibrations. I know that a mode shape is a pattern specific to a natural frequency of a system. That maens, the mode shape is determined under the context of free vibration, right? What kind of information can we obtained from the mode shape? Is the...

Is our universe a 3 sphere expanding in time into nothing? OR i

How do I rotate some shape in 2d space? That is, what factor do I multiply the x and y components to rotate my shape? Thanks.

Hi, Which formula may help to compute the effect to weight due to geoid shape of earth? I assume Earth is not rotating. Thanks

Before an object hit terminal velocity does the shape matter. In other words if you drop a small rectangle will it slow down in any way or will it keep on falling till it gets to it's terminal velocity. then another part to that is why when you drop a pencil or anything else shaped like that...

A chain with uniform linear density d and length L is tied at two ends to the ceiling. How to find its shape using Euler-Lagrange equations? (I know it can be done with other methods, but I want to know how to do it using E-L).

What does an electron look like? What is it made of? It has to be made of something? Can we/Have we been actually able see an electron?

I just want to make sure my understanding is correct. In a "flat" universe, the total density of the universe matches the "critical density". As a result, the universe will expand forever, and never "fall back" into itself. The shape of a flat universe, as the name suggests, is flat like a...

let ABDE and BCGH be squares lying outside the traingle ABC. The centres of these sqaures are P & Q respecitvely, and the midpoints of the line segments AC and DH are R & S respectively. Show that the points P,Q,R,S are vertices of a square? any ideas on how to do this please? the only hint i...

I have been reading an article about a theory of gravity that involves space being curved or warped. An example was given where a heavy weight, representing the sun, is placed in the centre of a trampoline, and a golf ball, representing the earth, is caused to circle the centre of the...

I recently read about a proposed liquid mirror telescope to be constructed on the moon. My question is one of mechanics, hence this not being in the astronomy section. My question is regarding the shape of the surface of a rotating liquid. The design will have a dish containing a thin layer...

Hi! Although nobody can see the shape of elementary particles, we always assume that their shapes are symmetrical, for example, sphere. Why? Is the symmetry a law? Otherwise, are there any other reasons? Patrick

What exactly is the solenoid shape? Is it just the shape of the coil with the core inside or do they refer to the shape of the magnetic field surrounding the coil?? Is this the solenoid, just the coil? Or are they talking about the magnetic field that surrounds the coil?

Lets get a bit of brain-storming going... What shape is the universe? Is it infinite in all three dimensions of x, y, z ? Is it spherical?

I'm not sure I even have enough time to prepare (a summer is very short). But still, I want to give myself a shot so I'm asking; what do I need to do good on the Putnam contest? Now I know this may sound like asking a question like "what do I need to one day walk on Mars?". So my real question...

I asked myself how the orbitals in a solid look like. Assume a crystal with a periodic structure, e.g. NaCl. The electrons in the crystal have energys according to the energy-band-model. Every band consists of that much discrete energy-levels that you might nearly call it continous. I know that...

Hi, I built this paper lamp and am trying to figure out what shape it would be classified as (dodecahedron, etc.). I've attached a picture of the shape, thanks for your help.

I would just like to ask a very elegant question. What is the shape of the universe?

There is a photo of a boeing 787 at http://en.wikipedia.org/wiki/Boeing_787 Is this a new wing shape? It looks very curved both in the plane of the wing and for a dihedral.

Homework Statement Ok, my problem has 3 smooth homogeneous cylinders(A,B,C), which are stacked in a V shaped trough.(the cylinders...look more like circles) are also all touching each other and each is touching a surface of the trough. The trough angles are Left = 30 deg and right = 45 deg...

i'm trying to understand stoke's theorem and am having trouble seeing whether the surface integral for a given surface changes with any change in its shape, or if it only changes depending on the cross sectional area perpendicular to the direction of the vector field. can anybody help me out?

When one of the quarks was discovered, I was in high school, and I said quarks are not spherical balls of mass. How could nucleons also be spheres if 3 quarks make up a nucleon?! I said atomic and subatomic particles have a poorly defined shape and something of a lack of material substance...

My hair is so curly, and I hate it so much.:frown: I wouldn't mind if it was wavy but it's curls a like 1cm length. And when dry it's especially hideous. I did a little research and found out that in curly hair the hair bulb inside the scalp is hook shaped, and in straight hair it's straight...

This isn't a homework question-- it is a general question about curve sketching in multivariable calculus. In order to draw graphs in 3D, we use level sets, then-- if the level sets are something "nice" like circles or parallel lines-- we take a cross section when y=0 and then transform the...

I have the following question: h(x) = (x^2-1)^3 a) Find the intervals of increase or decrease b) Find the local maximum and minimum values c) Find the intervals of concavity and the inflection points d) Use the informatin from parts (a)-(c) to sketch the graph Now I figure a good way...

hi every one I'm asked about the spacetime and his shape is spacetmie like the sea or waht? thank for everyone

What is the shape of salt crystals.??

How is it not possible that the universe is shaped like a sphere? What evidence do we have that shows it is expanding in a single drection or some variation that of? I recently heard that the origonal spherical theory doesn't work because of the increased speed of expansion, what I...
