[SIZE="5"]O' Christmas Tree, O' Christmas Tree It is that time of the year where evergreen trees are decorated and lit. Your photo for this contest must have, as the main subject, one or more christmas trees. The tree may or may not be decorated. [SIZE="4"]Contest Rules: 1. Any digital...

This was a question on the combinatorics midterm: if a tree contains only vertices of degree 5 and degree 1, and the tree has 4n+2 vertices, how many vertices of degree 5 are there? With k the # of vertices of degree 5 and j the # of vertices of degree 1, the accepted answer used the...

Suppose there is a tree of unknown height. I am standing 76 meters away from the tree and the top of the tree is 32 degrees from where I am standing. Could I find the height of the tree by this: 76 cos(32) =64 76 sin(32) =40 Magnitude = SQRT 64^2 + 40^2 Height of Tree equals 75 meters??

Question: Suppose a cannon is propped against a massive tree to reduce recoil when it fires. Then the range of the cannonball will be a) increased b) decreased c) unchanged My Answer: I am leaning (no pun intended) on a. Since the cannonball exerts a force on to the cannon, it recoils...

Hello, I am having some trouble with my red and black tree. I made up a parent method which finds the node before the node and then sets an iterator to that node. The code is below: private RBNode parent(Comparable x, RBNode i) { RBNode tmp = new RBNode(null,null,null); if(i==null ||...

I was wondering,could someone explain me how do minimal tree generators work?

COuld someone explain how in order and post order tree traversal work?I've searched through other websites but none of them would explain me in a way I could understand...Thanks in advance for the reply!

The lady who lives next to me asked if i could help her, it seems something had scared her cat up a tree (an old elm), she had been trying to coaxs it down all that morning, after several hours of calling etc the cat refused to move, so i started throwing little stones into the tree to see if i...

Apparently much to everyone's amazement Piper was unharmed and immediately scampered away... http://www.chicagotribune.com/news/showcase/sns-ap-falling-cat,1,653331.story Or there is a video at: http://www.local6.com/slideshow/news/8164570/detail.html?qs=;s=4;p=news;dm=ss;w=400l Without...

Dang Tree hugging cell phone! This stupid cell phone! The battery discharged in under 24 hours of simply being on standby! :devil: :devil: :devil: :devil: :devil: :devil: I hate everything. I hate life. I'm going to commit suicide. Wait cyrusabdollahi would like that. I plan on living...

I won't say who said it, but does this sound right to you? Dendrochronolgists on TV all say it so easy, you count the tree rings and the space in between, and that will tell you about the temperature and precipitation and how long the tree lived. Also: This sounds kind of dumb, but what about...

I cought him in my cherry tree in the early morning hours as i was going to school. He looks kinda worried, and he should be, if he was eating cherries out of my tree! :-p Enjoy the pic! (i hope it worked, I've never uploaded attachments before)

Like so. Can we already do this? Does anyone else want to? I think it would be helpful. For explaining some things, trees are just so much clearer than anything else. What I can do in code seems quite limited. N /\ / \ A -ness /\ / \ un- A...

hi, what's the spanning tree from the graph shown? it was on a test and I'm curious as to if I'm right or not. what i wrote down was a graph with edges 5, 6, 7, 8 and vertices A, B, C, D, E barneygumble742

Integral stopped by and suggested that I post a picture of an old growth tree here on the property [in Oregon]. Although it is the oldest and largest tree here, I don't know the height - I think I did estimate it once - and the age is between 150 and 250 years; with most people who would know...

If a healthy but somewhat direction impaired individual (mass = 81.9 kg) is jogging through the woods and runs straight into a large oak tree at 4.7 m/s. Rebound speed is measured at 4.2 m/s in the opposite direction. If the time of contact with the tree is 46 milliseconds, what is the magnitude...

[FONT=Arial]While exploring the canopy of the rainforest in equatorial South America, Anastasia falls from a branch 31.0 meters high. Exactly 1.4 seconds later Joe falls from the same branch. How high above the ground is Joe when Anastasia splats into the mud below? undefined

Can't seem to set this problem up Suppose a tree grows at a yearly rate equal to 1/10 of its height. If the tree is 10 ft tall now, how tall will it be in 5 years? dy/dx=x/10 y=(x^2)/20+c Im almost guessing this is right so far, if so will the 10ft be my constant?

Help my maple tree ! The maple tree in our front yard hasn't been going to well, the past year. We cut down as many dead branches as we could. Branches that are uninfected seem to be perfectly fine ( for now) the branches that are dead/dying have buds on them but the buds didn't open like the...

I'm trying to prove the following theorem using graph theory: I first tried to come up with an example: Graph G Vertices: a, b, c, d. Edges: ab, ac, ad, bc, cd. Spanning tree T Vertices: a, b, c, d. Edges: ab, ac, ad. (x = ac) Spanning tree T' Vertices: a, b, c, d. Edges: ad...

Hi Ho! ^_^ Actually, what is the definition of a complete binary tree? I have searched the Internet and come up with several definition. This problem is confusing enough. According to http://planetmath.org/encyclopedia/CompleteBinaryTree.html , "A complete binary tree is a binary tree...

I need to prove that for any full binary tree with N\geq1 leaves, that it has 2N-1 nodes. I can see this when looking at a tree, but I can't figure out how to prove this.

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

cat is climbed to the branch, holding to it with its paws. Cat is 8 m from ground. It starts falling. The question is that how fast must he rotate its tail for him to land on feet? Moment of inertia of its body is 50 000 g*cm^2 and moment of inertia oh his tail is 5 000 g*cm^2.

Tree Diagram Hello again! I'm stuck and need a little push. Referring to the diagram: out of a group of smokers, 20% are heavy smokers, 30% are light smokers, and 50% are non-smokers. A light smoker is twice as likely to die as a non-smoker but half as likely as a heavy smoker. H...

Hello there, Is it possible to have collisions in a AVL tree? My teacher asked me to write a hashing and collision resolution algorithm using AVL tree...maybe she means that i should store the tree node in a hashed array or something...what do u guys think?

Are there any relations between these two trees ?? Where can i find source code to build a splay tree ? I have heard that if we applied the ideas of SINGLE ROTATION[/color] and DOUBLE ROTATION[/color] which are used in AVL tree, we can then build SPLAY tree easier, is this correct ? Thanks a...

many qsnts : unchanging light, time not time, &more I may be about to make myself look like a total ass, but, please, be merciful (my knowledge of physics and math is slight --> but I want to change that). I have been reading, albeit somewhat topically, about relativity. I have a BUNCH...

Today as I was walking home, I came across a tree which had been recently cut down. The part where the cut was was totally wet as was a lot of the trunk's bark and it was still dripping. Not only that, but there liquid was relatively sticky (flowed well enough, but when I touched it it certainly...

I used to know about this kind of animation made by some students in Washington States University (?), it was really an interesting project, I think people who don't know anything about tree structures, just need to give it a look, then they can grasp how they work immediately, I have recently...

this is by no means polished. i will be working out my thoughts as i write. whenever i try to understand the concept of self, i visualize a tree. i am the tree but this physical me might only be a branch of the total me. the trunk is my core being(soul, spirit, etc?) and the big branches...

a landscaper tries to plumb a tree by applying a 240 N forces. two helpers attempt to plumb the same tree with one pulling at point b and the other pushing with a parallel force at point c. determine these two forces so they are equivalent to the single 240 N force. the force is at point A. it...

need help on physics problems 1)The silhouette of a Christmas tree is an isosceles triangle. The angle at the top of the triangle is 10.2 degrees, and the base measures 1.67 m across. How tall is the tree? 2) A person is standing at the edge of the water and looking out at the ocean (see...

Like Queen Elizabeth gives the nation a Christmas address, President Bush should set an example for America and the world by letting his actions speak louder than words: BURN THE WHITE HOUSE XMAS TREE! He could then use the unique opportunity (since it'll undoubtedly attract some attention) to...

Has anyone here ever been tree bending?

will you tell me if my answer is correct? An apple falls from a tree and 0.5 second later hits the ground. how fst is the apple falling when it hits the ground. i think it is v = gt 5.0m/s2
