What'S The Difference Between V-Rocker And Flying V For Snowboards?

From Snowboarding Forum:

What's the difference between v-rocker and flying v for snowboards? I tried v-rocker but I heard flying v is better. Which one should I buy? And am pretty good i've been riding for 8 years now.

Answer: V Rocker is a fully convex board that is preferred for boxes, rails, and jibbing. Some also prefer this shape for riding moguls and deep powder too. Generally this shape tends to be less poppy at nose and tail and is not the best choice for jumps or carving on hard packed snow. Lib Tech, Never Summer, and Rome all claim to have solved the "noodle" feel of nose and tail through additional inserts. I can confirm from experience that Lib Tech succeeded and Rome did not (don't know about Never Summer or Burton). Flying V is a dual-camber design - convex between feet, flat under feet, cambered outside feet. These are generally considered all-purpose boards and handle virtually all terrain equally well, but are especially good in powder and loose, spring snow. The design does lose a little bit of pop at nose and tail, but not very much. The only people that I've met that don't like this design are the ones that go for big air and stick to standard camber.

How To Prove F Has Finitely Many Zeroes In Compact Subsets Of V?

From Mathematics Forum:

How to prove f has finitely many zeroes in compact subsets of V? Suppose V is a connected open subset of C and f:V → C is polymorphic. Show that, in compact subsets of V, f has finitely many zeroes. Thank you.

Answer: Well, this is certainly true if f is not identically zero. You, of course, forgot to add this assumption to your assertion. So, I'll suppose that f is not identically 0. If this is the case, your assertion follows from the following theorem, whose proof you find in any book on Complex Analysis: Let V and f be as in your assertion and let Z(V) be the set of all zeroes of f in V. If Z(V) has a limit point in V, then f is identically 0 in V (this follows from the fact the polymorphic functions are given by power series). Suppose K ⊂ V is compact. Then (Heine/Borel theorem), K is closed and bounded. So, Z(K) = {z ∈ K : f(z) = 0} is bounded. If Z(K) is infinite, then (Bolzano/Weierstrass theorem) Z(K) has a limit point a. Since Z(K) ⊂ Z(V) and Z(K) ⊂ K, a is automatically a limit point of both Z(V) and K. Since K ⊂ V is closed, a ∈ K and, therefore, a ∈ V. We conclude Z(V) has a limit point in V (the domain of f). According to the theorem we mentioned, f, contrarily to our assumption, is identically 0. It follows that, in every compact subset of V, f must have finitely many (possibly none) zeroes. The assumption that f is not identically 0 is, of course, essential for your assertion to be always true for every connected and open subset of C.

How Can I Transfer The Data In My V-Box To DVD Without A DVD Recorder?

From Tito & DVDs Forum:

How can I transfer the data in my v-box to DVD without a DVD recorder? I have some TV programmes recorded and keep them in my v-box. Unfortunately I don't have a DVD recorder, but have a laptop which can deal with DVD. I would like to know how to transfer the data from v-box to DVD without a DVD recorder but with a laptop. Is it impossible without a DVD recorder? I appreciate it if you let me know the way to solve my problem.

Answer: it's not impossible.. unless your laptop has a video card that includes video capture (most laptops don't, ), you'd need a SUB video grabber to record the programmes to your laptop hard drive (go to amazon and search "video grabber USB" or "video capture USB" to see what I mean). once on your hard drive you use DVD burning software or the software that comes with the grabber to burn them to disc. they're cheaper than DVD recorders, but the cheap ones are annoying because of dodgy quality (things like your screen saver kicking in can mess up a recording) and badly written software, and the better ones are annoying because of overcomplicated software, and you usually have to learn all about video configuration settings. a DVD recorder is more expensive but less complicated and more reliable. unfortunately either way, DVD recorder or SUB video capture, you'll have to re-record the programmes in real time, playing on your v-box while recording on your other device; you can't just get the data off the v-box's hard drive, it's written in v-box language that your computer won't understand- that's the whole point of v-boxes and sky boxes, to prevent you getting the raw data so that you have to keep your box. sorry!

Find The Initial Velocity V Required To Achieve A Height Of H?

From Mathematics Forum:

Find the initial velocity v required to achieve a height of H? A ball is thrown vertically upward with initial velocity v. Find the maximum height H of the ball as a function of v. Then find the initial velocity v required to achieve a height of H. The maximum height H of the ball as a function of v is -1/2(32)[v^2/32^2]+v^2/32 What is the initial velocity v required to achieve given height H ?

Answer: Kinetic Energy equals Potential Energy yields: (1/2)(m)(v^2) = mgh (1/2)v^2 = gh h = (1/2)(v^2) / g <== First Answer v^2 = 2gh v = Sqrt(2gh) <== Second Answer

What'S A Good Classroom Demonstration To Illustrate The Delta-V Required For A Change In Orbital Inclination?

From Astronomy & Space Forum:

What's a good classroom demonstration to illustrate the delta-v required for a change in orbital inclination? What is a good, clear way of demonstrating in the classroom why it relatively expensive, in terms of delta-v, to change orbital inclination. (For simplicity's sake, let's make both orbits circular and have the same radius.) A bicycle wheel comes to mind, but tipping it one way or the other as the wheel spins does not immediately impress on you, as one scales it up in their imagination, the delta-v required for delta-i.

Answer: I was interested in this question and its answer..Could it be that this video (or its neighbors at Youtube) would solve this illustration problem..There are several. The first is................http://www.youtube.com/watch?v=2QRfkG7jOfY. This video is entitled "Aerodynamic Design History of the Space Orbital Shuttle"..It is an MIT video.....(subtitled "from sub- to hypersonic and back") Good luck..............

What Is The New Speed V’ Away From The Wall When Rolling Motion Is Re-Established?

From Physics Forum:

What is the new speed v’ away from the wall when rolling motion is re-established? A wheel (mass M, radius R) rolls with speed v and angular velocity w (v=ωR) and collides elastically with a wall. Immediately after the collision it has v away from the wall, but the same ω as before – so it’s skidding, not rolling. Friction at the floor will eventually re-establish rolling motion, by doing negative work on the system and applying a torque that will change ω. What is the new speed v’ away from the wall when rolling motion is re-established?

Answer: That's an interesting question! First, let's set up direction conventions. Let's say: * The wall is on the left, so the wheel bounces off to the right. Let's call "rightward" the positive linear direction. * Let's call "clockwise" the positive angular direction. (That means the wheel's rotation is negative immediately after the bounce.) During skidding, the force of friction is more or less constant (given by: (normal force)×(coef. of sliding friction)), so we can say that "Ff" is the (constant) force of friction during the skidding phase. The force Ff produces a torque on the wheel, in the amount of: τ = (Ff)R. (This is a positive torque, since Ff points to the left and therefore tends to drive the wheel clockwise.) We know that the angular acceleration is given by: α = τ/I = (Ff)R/I where "I" is the wheel's moment of inertia. I'm not sure what kind of wheel this is, but its moment of inertial can be represented as: I = βmR², for some "β" that depends on how the wheel's mass is distributed. (It's some constant between 0 and 1.) So we can write: α = (Ff)/(βmR) At the same time, the ball's linear acceleration is: a = -Ff/m (Here we use negative Ff, since the force points toward the left) With these two values, we can write the ball's angular and linear velocities as a function of time: ω(t) = ω0 + αt = ω0 + (Ff)t/(βmR) (where ω0 is the ball's angular velocity right after collision) and: v(t) = V + at = V + (−Ff/m)t (where V is the ball's linear velocity right after collision) We are also given that ω0 = −v0/R, so we can rewrite the ω(t) equation as: ω(t) = −v0/R + (Ff)t/(βmR) Now, at some time t′, rolling is re-established. That means: v(t′) = ω(t′)R or: v0 + (-Ff/m)t′ = −v0 + (Ff)t′/(βm) From which: t′ = 2(v0)mβ/[Ff(1+β)] Now plug that value back into the "v(t)" equation: v′ = v(t′) = V + (-Ff/m)2(v0)mβ/[Ff(1+β)] = V - 2(v0)β/(1+β) = v0(1 - 2β/(1+β)) = v0(1-β)/(1+β) So for example, if you assume that the wheel has a uniform density, then β=½, in which case v′ = v0/3.

How Does The Fit Of American Apparel V-Necks Compare To Their Regular T-Shirts?

From Fashion & Accessories Forum:

How does the fit of American Apparel v-necks compare to their regular t-shirts? I own 1 unisex deep v and 1 unisex regular v-neck. I know that the regular v-neck runs slightly bigger than the deep, but how do they compare to the regular t-shirts as far as fit? I wear an XS in both v-necks for reference.

Answer: The fit of most of the crew necks (2001, BB, TR, 6401) is closer to the regular v neck (2456) Go with XS in unisex styles and a S in women's.

How Can Girls Get V Lines On Their Stomach?

From Other - Health & Beauty Forum:

How can girls get v lines on their stomach? I'm 15 and really want v lines on my stomach. I dot think I need to lose much weight, I'm just below 7 stone, but what exercises do I need to do just to get the lines? I don't wanna a six pack or anything though

Answer: Don't lose any weight. Mostly, it's sit ups. You will get a six pack, but keep going till you see the v lines, and then when you have them, don't exercise your stomach. Just jog regularly to keep them there, but don't exercise stomach muscles if you want the six pack gone.

Can You Explain The Difference Between The Pronunciation Of V And W In Dutch?

From Languages Forum:

Can you explain the difference between the pronunciation of v and w in Dutch? Such as v as in van or boor and w as in winkel It would also help if you could explain the difference in the articulation of the two sounds- how you produce them as well as what they sound like

Answer: V is à blowing sound like you would blow at à feather. W is much like THE English W, instead of THE shape you would make as with an IO sound. Make THE shape of an EEO.
