Why absolute rest and absolute motion do not exist?
Absolute rest and absolute motion do not exist because motion is relative; it depends on the observer's frame of reference. According to Einstein's theory of relativity, all motion is measured relative to another object, meaning there is no universal state of rest or motion. Furthermore, even in a seemingly stationary state, factors like gravitational forces and cosmic movements can influence perception, reinforcing that all states are relative rather than absolute.
What is the advantage of relative frequency distribution vs distribution frequency?
These help to distribute the frequency much better than the latter. The noise might not be as loud or boisterous this way.
Why would relative frequency be better than frequency while comparing two different groups?
you are aw some * * * * * Sadly you are not since you can't even spell the word. Relative frequency would be better because the two groups may be of different size.
What is absolute error formula?
Absolute and Relative Error Absolute and relative error are two types of error with which every experimental scientist should be familiar. The differences are important. Absolute Error: Absolute error is the amount of physical error in a measurement, period. Let's say a meter stick is used to measure a given distance. The error is rather hastily made, but it is good to ±1mm. This is the absolute error of the measurement. That is, absolute error = ±1mm (0.001m). In terms common to Error Propagation absolute error = Δx where x is any variable. Relative Error: Relative error gives an indication of how good a measurement is relative to the size of the thing being measured. Let's say that two students measure two objects with a meter stick. One student measures the height of a room and gets a value of 3.215 meters ±1mm (0.001m). Another student measures the height of a small cylinder and measures 0.075 meters ±1mm (0.001m). Clearly, the overall accuracy of the ceiling height is much better than that of the 7.5 cm cylinder. The comparative accuracy of these measurements can be determined by looking at their relative errors. relative error = absolute error value of thing measured or in terms common to Error Propagation relative error = Δx x where x is any variable. Now, in our example, relative errorceiling height = 0.001m 3.125m •100 = 0.0003% relativeerrorcylinder height = 0.001m 0.075m •100 = 0.01% Clearly, the relative error in the ceiling height is considerably smaller than the relative error in the cylinder height even though the amount of absolute error is the same in each case.
Can relative density be more than 100 percent?
Relative density, also known as specific gravity, is a ratio of the density of a substance to the density of a reference substance (usually water for liquids and solids). Since this ratio compares densities, it is typically expressed as a dimensionless number and cannot exceed 100 percent (or a value of 1) for a substance with respect to water. However, if the reference substance is different or if the context implies a comparison with a different material, the relative density could have values greater than 1, but it still represents a comparative measure rather than an absolute percentage.
What are the differences between relative concepts and absolute concepts?
*Absolute: free from imperfection; complete; perfect.* Relative to be compared to something elseIf you get what i mean, like"einstein's_theory_of_relativity:" Definition for einstein's theory of relativity:relativity: (physics) the theory that space and time are relative concepts rather than absolute concepts. Relative means it can be compared to something else like this case its not unique, but to be Absolute it is unique and it has no comparison.
How are histograms and bar graphs different?
In a bar graph, the height of the bars is relative to the frequency. In a histogram, the area of the bars is relative to the frequency. Because it deals with area, the label on the y-axis is "frequency density" rather than just "frequency"
Why do chemists use relative masses of atoms compared to a reference isotope rather than absolute masses in their calculations?
Chemists use relative masses of atoms compared to a reference isotope because it allows for easier comparison and calculation of chemical reactions. Absolute masses can vary, but relative masses provide a consistent point of reference for analysis.
What is offset address?
An offset address is a relative address rather than an absolute address. You use offsets to refer to memory relative to an absolute address. For instance, array indices are implemented using offsets from the start address of the array, such that element 0 is at offset 0 and element 5 is at offset 5.
Is a fossil a relative or absolute time?
It depends. If you are comparing it to something then it is relative. But if your give it a specific age/year, then it is absolute. ex. Relative: The fossil is younger than the shale. Absolute: The fossils is 1000 years old. *note; even if the age is wrong it would still be classified as absolute time
Why relative frequency distribution better than frequency distribution?
Not all statisticians would agree that the statement is true.
Does radioactive dating tell the relative age of rocks?
Radioactive dating techniques, such as radiocarbon dating or uranium-lead dating, provide an absolute age for rocks by measuring the decay of radioactive isotopes within them. This helps determine the actual age of rocks rather than their relative age.
What does relative position mean?
Relative position refers to the location of an object in relation to another object, rather than its absolute position in space. It describes how one object is situated or oriented with respect to another object, providing a sense of direction or proximity between the two.
What is a radio wave's relative wavelength and frequency is?
The wave length and frequency of course vary, the frequency ranges from 3kHz to 300 GHz. The wavelengths are longer than infrared.
What is the advantage of relative frequency distribution vs distribution frequency?
These help to distribute the frequency much better than the latter. The noise might not be as loud or boisterous this way.
What does a cumulative relative frequency of .4 mean?
If the cumulative relative frequency when the variable X takes the value x, it means that 0.4 (or 40%) of the values of the variable X are less than or equal to x.
Why would relative frequency be better than frequency while comparing two different groups?
you are aw some * * * * * Sadly you are not since you can't even spell the word. Relative frequency would be better because the two groups may be of different size.
