In binary phase diagram, We draw a tie line to know the composition of the liquid phase or the solid phase. Where the tie line is just a horizontal line. The question is why doesn't the liquid or solid phase composition change as you change the general composition of the alloy? Why does the...

The society on Jupiter's moon Io has a very odd way of counting. They count in binary using special counters: small discs with 0 printed on one side and 1 on the other. To increase speed when counting they made a rule: Rule #1: To get the next number in the sequence, only one counter can be...

A star or a planet is a material object, while a black hole is an 'immaterial' spacetime object. Does the material or 'immaterial' nature of an object make any difference in how it curves or travels through spacetime as it manifests gravitation (apart from the powerful gravitation near a black...

I've tackled a lot so far! I've created methods to delete, get the weight, and sort the tree by name. My goal is to have my switch criteria change how the tree is sorted, either by weight or by name. I haven't figured out how to implement it within my switchCriteria() method, so I've been...

I am having a hard time implementing comparing a given String name with the names of the Dog objects in my binary Search Tree. The problem comes from my containsRecursive() method. I need to use a String name to find if the name is already in my Binary Search Tree.Here's what I've tried...

Okay, so for years the typical mechanism used to describe a white dwarf supernova explosion was that a white dwarf accumulates matter from a main sequence binary companion. Then a few years later, the concept of two white dwarfs crashing into each other came up. With the main sequence companion...

How many neutron stars are binaries of other neutron stars? Hulse-Taylor binary, discovered in 1974, has orbital period of 7,75 hours. And the pulsar component rotates at 59 milliseconds. The orbit is also eccentric, from 1,1 to 4,8 solar radii. Expected to merge in 300 million years. PSR...

On November 15, 2017, LIGO Scientific Collaboration announced the observation of another binary black hole coalescence. The gravitational waves were observed by the twin LIGO detectors on June 8, 2017. This is the lightest black hole binary observed so far, with component masses 12 and 7 times...

I am a Physics undergraduate at the University of Texas at Arlington. I am currently taking an Astrophysics class in which my professor talked about the inclination angle of the orbital plane of the binary star system and how it is impossible to determine that angle. I was wondering why is it...

Hello, I was wondering: Since the mind works on electrical signals, it must work on binary codes, because there is electrical signal or not. If so, is the only thing that distinguishes us from a computer the length of the "bit"? What do you think? Thanks.

Hi there. There is currently a Binary puzzle being solved in the game Word Of Warcraft. In the puzzle, there are 10 levers which can each be placed in 9 different positions 1-9. So for example, the solution may be 1459275918. So far the community is stumped. The code given is below, I would...

KIC 8462852, aka ‘Tabby’s Star’ is in the news again, with more BS ideas about "alien megastructures'. Isn't the simplest and most likely explanation for the intensity variability that it is a binary or multiple star system and that the Earth is in the same plane as the mutual orbit ?

This is the problem given at my basic astronomy course. If I turn it in within a month correctly, I get 10 extra points in the finals. Problem: We have binary star system consisting of Star A and Star B. Astronomers have observed it for 11 years, during which it has moved from point A to point...

Hi, I am trying to write a function which would take two arguments: -> number of bits (which are a binary 0 or 1 value) N -> and acceptable number of mismatching bits M The function would statistically determine the probability of having M or less mismatching bits when randomly generating two N...

Homework Statement In 2009, astronomers found convincing evidence of two such black holes orbiting as a binary system. From data collected, they estimated that the separation of the black holes was 3.2 × 1015 m and that their masses were 1.6 × 1039 kg and 4.0 × 1037 kg. The black holes orbit...

Hi, I'm new to the forum and have an idea for a novel. I can't find anything on this question so I thought I'd sign up for a forum to ask. I'm not a scientist and lack much of the higher technical knowledge. Here's my question: Most planets in close orbits (they'd have to be to support liquid...

I have two questions over linear and binary serch. 1. Homework Statement Q1: In binary search, after three comparisons have been made, only ___ of the array will be left to search. Q2: The maximum number of comparisons that a binary search function will make when searching for a value in a...

So a spherically symmetric object, by Birkhoff's theorem, does not emit gravitational waves. Is this why we look to binaries, so that there is some rotation of the objects with respect to each other breaking the spherical symmetry? Or mainly because the gravitational radiation is much greater...

Homework Statement Suppose that * is an associative binary operation on a set S. Let ##H=\{a \in S ~| ~a*x=x*a, ~ \forall x \in S\}##. Show that * is closed under H. Homework EquationsThe Attempt at a Solution Let b and c be two different elements in H. We need to show that b*c is also in H...

Homework Statement Consider the binary structure given by multiplication mod 20 on {4, 8, 12, 16}. Is this a group? If not, why not? Homework EquationsThe Attempt at a Solution I started by constructing a Cayley table, and working things out. It turns out that 16 acts as an identity element, 4...

We can think of a notation being assigned to some ordinal o≥ω when there exists some total and onto function g for which: i) the domain is N ii) the co-domain is the set of all ordinals less than o Now consider the following set: S={(x,y) | g(x) < g(y) } Let the characteristic function of...

So a 3 bit 2 input multiplier has a maximum of 6 bits and the max integer product is 49. Problem is I have no idea displaying it in 2 seven segment displays since the 74LS48 decoder only has 4 inputs and 7 output, only good for a single 7 seg. And we are required only to use ICs which is rather...

I may be writing a story, set on a rocky planet, 15 times the size of Earth, around a binary dwarf star (one red, one orange). What kind of flora and fauna can I expect?

How can planets exist in star systems with two or three stars? Shouldn't the planets' orbits get severely disturbed by the other stars?

Homework Statement So in C an integer is stored as a 32 byte value. Were the 32nd byte is the byte that determines if the value is negative or positive. I created a loop were I set the integer i equal to 1. Each time I cycle through the loop I left shift the variable i by one. Meaning that...

This one confused me a little bit. You have to carry the one and put it into the next 1 + 1, what would be the rule in this situation? Not sure if this ever happens in decimal addition.

I need to complete this. Let's say I have 4 bits with 2 bits set as 1, 0011. The total number of permutations for this number is 0011, 0101, 0110, 1001, 1010, 1100, 6 cases. This can be computed using the calculation. 4! / ((2!)(4-2)!) = 6 Now I want to be able to find the nth sequence, for...

Wikipedia seems to think that a binary system is defined by a single semi-major axis, but I've seen other sources such as hyperphysics that define it using two semi-major axes. Is the semi-major axis of the system simply the average of the two?

I'm writing a C program to simulate the orbits of a binary system with a 4th order Runge-Kutta method; basically I'm considering the 2 bodies rotating around a fictitious 3rd body(which would be their center of mass) and I turned down the reciprocal gravitational pulls between the bodies to...

What happens, if instead of having any pointer pointing to a node's parent, we had pointer pointing to the node's successor? We know, that Searching would remain the same. But in my opinion Insertion and Deletion would change. This would happen, because in insertion, we would be needed to find...
