We know that the hadron's are made up of 2 or 3 quarks.
Each of the quark has spin up or spin down state.
Now if i consider an example of a hadron made from 3 quarks (e.g. proton -spin 1/2 Baryon, consist quarks u,u,d)
at least two of them are in the same state of spin may be up or down
this is against the pauli's principle
so the quark in hadron must have different colors.
whatever the spin they must have different colors
Question 4 a) Why must the quark in a hadron have different colors? Would they have...
Why do LED diodes have different colors ?
14.1 A particular cell phone case is available in a choice of four different colors. A store sells all four colors. To test the hypothesis that sales are equally divided among the four col- ors, a random sample of 100 purchases is identified. a. If the resulting X2 value were 6.4, what conclusion would you reach when using a test with significance level 0.05? b. What conclusion would be appropriate at significance level 0.01 ifX2-1539 c. If there were six...
Briefly discuss the essentials of the quark model for strongly interacting particles. In your discussion specify the baryon number, spin and charge of each of the quarks, explain what is meant by flavour, colour(-charge) and quark confinement. State the quark composition of mesons and hadrons, and explain why there are only quark- antiquark combinations, and combinations of three quarks and of three anti-quarks 4. (a) (4 marks) 0, Л0--, and According to the Eightfold Way, the light baryons p, n,...
#6. Is it possible to have a laser utilizing a single element amplify two different colors of light? If so, explain why. If not, explain why not. Use mumbers (you can make them up) to help your explanations. Bonus Determine the temperature at which monatomic hydrogen atoms must reach to jump into the first excited state.
Why must X-rays be used in crystal structure determinations rather than visible light? Why must the light used in crystal structure determinations be monochromatic? That is, what would happen to a peak in an XRD pattern if polychromatic rather than monochromatic light were used?

4. Three fair dice have different colors: red, blue, and yellow. These three dice are rolled and the face value of each is recorded as R, B, Y, respectively. (a) Compute the probability that B< Y < R, given all the numbers are different; (b) Compute the probability that B< Y< R.
What would the correct answer for this question be and why? And why would the other choices be wrong? We were unable to transcribe this imageQuestion 85 Which of the following would most strongly reduce the strength of a real-time colony PCR? O A. 16S rRNA has minor SNPs between different species of bacteria. O B. Consistently running the PCR amplification for one O C. Different species of bacteria have different numbers O D. Different species of bacteria express 16S...
There is a group of kindergarten children observed who have two different shirt colors, red and blue. Red = 1 and Blue = 0. The sample size of 8 can be formed as 1 1 0 0 0 0 1 0. What is the probability that 6 or more children will come in with a red shirt? Please show all calculations and use of formulas to find the percentage.
Problem 4> We have four colors (red, black, white, blue) to encode. In this encoding, we would like the receiver to be able to correct 2-bit errors. Please provide the appropriate four 8-bit code-words for the colors. There is more than one solution. It is enough to show one.
