# What is Nodes: Definition and 126 Discussions

Inguinal lymph nodes are lymph nodes in the human groin. Located in the femoral triangle of the inguinal region, they are grouped into superficial and deep lymph nodes. The superficial have three divisions: the superomedial, superolateral, and inferior superficial.

1. ### Comp Sci Creating a City Graph with Nodes & Edges

Edit: Trying to fix the formatting... class Node(object): def __init__(self, name): self.name = str(name) def get_name(self): return self.name def __str__(self): return self.name class Edge(object): def __init__(self, src, dest): self.src =...
2. ### Displacement nodes for overtones

(4 / 3) * (1.8) = 2.4 = lambda 1st overtone: 2.4 / 4 = .6; (2.4 * 3) / 4 = 1.8
3. ### Where are the pressure nodes on a standing acoustic wave in water?

I have calculated the wave length of a 36 kHz acoustic wave in 20 °C water to be around 41.16mm. Suppose I have a transducer that produces a 36 kHz acoustic wave and a small water container with a length of 41.6 mm. How will the standing acoustic wave look like, which is produced by the...
4. ### Comp Sci What is Node and Edge Betweenness in Star Network?

What is "node betweenness of node 0", and" edge betweenness of edge e01" in the question = ? What is B there in the solution? why e34 calculated instead of e01? (as highlighted) Thank you

41. ### How many nodal lines for two point sources at 2.5 lamda separation?

Homework Statement How many nodal lines are created by two point sources emitting at the same wavelength that are separated by a distance equal to 2.5 lamda? Homework Equations My textbook says, "If two coherent sources located a distance d apart emit identical waves of wavelength lamda, then...
42. ### Direction of Current between nodes

Say for example you had the following circuit. Since it is hard to determine which source will have a bigger influence on current I am unsure of how I would determine which way the current would flow between each node.
43. ### Equation of motion for a massless spring system

Homework Statement Homework Equations f_spring = k(x_near - x_far) The Attempt at a Solution a. FBD: The force goes through the nodes, and the sum of the forces must be 0 because the nodes are massless. Therefore, kx_1 = x(t) So x_1(t) = x(t)/k b. FBD: For this system, the parallel...
44. ### Find the potential difference between 2 junctions (nodes)

Hello, I'm wondering how to determine the value of the potential difference between two points (junctions specifically) in a circuit with 2 emfs. The junctions are points x and y in the circuit below. I thought I could use the junction rule to determine the current at each junction...
45. ### Find Energy of Antinode & Node in Standing Wave of Time Period T

a standing wave of time period T is set up in a string clamped between two rigid supports. at t=0 antinode is at its maximum diaplacement 2A. at what time will the energy of antinode be equal to that of a node? what i know is... that node has zero amplitude..n antinode has maximum...
46. ### Energy of nodes and anti nodes

at what time will the energy of a node be equal to energy of an antinode when the time period is T?
47. ### How does the Sync.field synchronize slave nodes in a serial communic?

Serial communication:Following the Break is the Sync.field. The literature says that as there are no quartz or ceramic resonators in the slave nodes,the sync.field is transported before the protected ID field.I do not understand 2 things here: 1.What does it actually mean for the slave nodes...
48. ### M-ary Tree: Given Nodes, find leaves

Homework Statement (I'm struggling with trees now so I expect to have a lot more questions on here like this) I have a 4-ary tree with 173 nodes. How many leaves do I have? Homework Equations The Attempt at a Solution So I know that each node, if it is not a leaf, will have 4...
49. ### Equivalent resistance between two nodes help

Homework Statement Homework Equations Parallel-Series resistors combinations. The Attempt at a Solution Using an approach much like the one used to find the Thevinin resistance: 1- Open circuit between A and B (R1, R2, R3), and short circuit the voltage source. 2- (R4//R5)+R6=170 3-...
50. ### Deleting Nodes w/ 2 Children from a BST

I guess the problem is mostly due to the fact that I still don't understand recursion very well. What my prof is trying to do is to teach it to us by directly applying it to data structures that may use them, such as the Binary Search Tree. I've already been able to delete a node with no...
