what is the order of magnitude used for?
428257
Orders of magnitude are used to make approximate comparisons. If numbers differ by one order of magnitude, x is about ten times different in quantity than y. If values differ by two orders of magnitude, they differ by a factor of about 100.

What is the difference between magnitude and intensity? Magnitude is a measure of earthquake size and remains unchanged with distance from the earthquake. Intensity, however, describes the degree of shaking caused by an earthquake at a given place and decreases with distance from the earthquake epicentre.

The apparent magnitude is the observed visible brightness from Earth which depends on the distance of the object. The absolute magnitude is the apparent magnitude at a distance of 10 pc (3.1×1017 m), therefore the bolometric absolute magnitude is a logarithmic measure of the bolometric luminosity.

How do I write 12 in scientific notation? Same drill. It's equal to 1.2 times-- well, we only have 1 digit between the 1 and the decimal spot, or the decimal point. So it's 1.2 times 10 to the first power, or 1.2 times 10, which is definitely equal to 12.

Summary: Cardinal and Ordinal Numbers We use ordinal numbers to rank or order things (e.g., first, second, third). Most ordinal numbers are written as words in formal writing, but larger values can be written as numerals.

So let us let our ordinals start at zero: an element's ordinal (subscript) equals the number of elements preceding it in the sequence. ... — zero as a most natural number. Remark Many programming languages have been designed without due attention to this detail.

The word "order" is used in a number of different ways in mathematics. Most commonly, it refers to the number of elements in (e.g., conjugacy class order, graph order, group order, etc.) or characterizes the largest term (e.g., curve order, surface order, polynomial order) appearing in a mathematical object.

j stands for complex part of a complex number in python, it is same as iota(i) in maths. the magnitude of 3+4j=√(3**2+4**2)=5(abs is magnitude of a complex number in maths) for more details, refer chapter complex numbers in maths.

The answer is 9 According to the order of operations, division and multiplication have the same precedence, so the correct order is to evaluate from left to right. First take 6 and divide it by 2, and then multiply by 3.

to be used widely. And like for all pressure units, SI or not SI, we can use the common prefixes/coefficients in front of them, most commonly used are milli (1/100), centi (1/10), hecto (100), kilo (1000) and mega (1000000).

Magnitude and Intensity measure different characteristics of earthquakes. Magnitude measures the energy released at the source of the earthquake. Magnitude is determined from measurements on seismographs. Intensity measures the strength of shaking produced by the earthquake at a certain location.

Exponents can be used in a variety of ways to represent length. Specifically, negative exponents are used to represent how small something is. Bats, for example, are pretty tiny creatures. Zoologists use negative exponents to measure different parts of bats, such as their wingspan.

The prefixes indicate whether the unit is a multiple or a fraction of the base ten. It allows the reduction of zeros of a very small number or a very larger number such as 0.000000001 meter and 7,500,000 Joules into 1 nanometer and 7.5 Megajoules respectively.

Writing numbers based upon powers of ten is called exponential notation. Because exponential notation is used a great deal by scientists, it is also called scientific notation. Exponential notation and scientific notation are two names for the same thing.

The magnitude scale is logarithmic. That just means that if you add 1 to an earthquake's magnitude, you multiply the shaking by 10. ... For example, if the magnitude of one quake is 6 and another is 4, than the difference in magnitudes is 2, so the stronger earthquake shakes 10^2 or 100 times as hard as the milder one.
