A valid quark combination is one that follows the rules of the strong nuclear force. For example, a valid quark combination could be a proton, which consists of two up quarks and one down quark.

When were quarks invented?

Quarks were discovered by using particle accelerators to smash subatomic particles. These particle accelerators, beginning with the machine at the Stanford Linear Accelerator Center (SLAC), accelerated charged particles to tremendous speeds and then forced them to collide with or smash into target material. The collisions cause protons and neutrons to break apart, and quarks were identified in the particle tracks as some of the "broken bits" that scattered following the collisions. The quark, which was proposed independently by physicists Murray Gell-Mann and George Zweig in 1964, was confirmed when investigators at SLAC found the first quark in 1968. It took until 1995 to identify the last type of quark when the top quark was spotted in collision results at Fermilab.

Which of the following are not vector directions. 35 degrees inside 35 degrees north of east north outside 45 degrees?

None of the options listed are valid vector directions. The first two options are specific angles (35 degrees inside and 35 degrees north of east), while the third option is also an angle direction (north outside 45 degrees). A vector direction should specify a coordinate system (e.g., east, west, north, south) and a magnitude (e.g., 5 meters).


Albert Einstein's famous formula E mc2 in practally valid or not?

Yes, Albert Einstein's formula E=mc^2 is practically valid. It is a fundamental equation in physics that relates energy (E) to mass (m) and the speed of light (c). This equation has been proven through numerous experiments and is a cornerstone in understanding the relationship between energy and matter.


How can you ensure the accuracy of your results which conducting a scientific investigation?

You can ensure the accuracy of your results by using a control group to compare against the experimental group, conducting multiple trials to account for variability, following standardized protocols and procedures, and taking careful measurements and recording data accurately.


What does valid frequency mean?

Valid frequency refers to the number of times an event, behavior, or data point occurs within a specific time frame. It is used in statistical analysis to measure the reliability and consistency of patterns within the data set. Valid frequency helps researchers make accurate conclusions and predictions based on the frequency of specific occurrences.

What is the effective address generated by the following combinations if they are valid. If not give reason. Initially BX0x0100 SI0x0010 DI0x0001 BP0x0200 and SP0xFFFF a. bx-si b. bx-bp c. bx plus 10?

To calculate the effective addresses for the given combinations: a. BX - SI: This results in 0x0100 - 0x0010 = 0x00F0, which is valid. b. BX - BP: This gives 0x0100 - 0x0200 = 0xFF00, which is also valid. c. BX + 10: This equals 0x0100 + 0x000A = 0x010A, which is valid. All combinations are valid and yield effective addresses.

How can you make 34 as tens and ones in five ways?

You can make 34 as tens and ones in the following five ways: 30 (tens) + 4 (ones) 20 (tens) + 14 (ones) 10 (tens) + 24 (ones) 0 (tens) + 34 (ones) 33 (ones) + 1 (tens) However, the last option is not a valid representation of tens and ones in the traditional sense. So the valid combinations would focus on using 30, 20, and 10 as tens, each followed by the corresponding ones to total 34.
