Basic Math: Scientific Notation. In this section, you will occasionally be asked to answer some questions, 3x10 8. Whenever a problem set is given, you should answer the questions on a separate sheet of paper and then verify your answers by clicking on "Answers.

These two ideas together are enough to require that we think of the universe as a 4-dimensional space-time in which the time between two events depends on who measures it, and whether two things happen at the same time depends on who's asking. We can most easily understand a sequence of events by using a space-time diagram. I'll use one space dimension instead of 3, because I can't draw 4-D diagrams. The diagram shows that there is a limited region of space that we can know about: the region that lies within our past light cone. When the light hits the mirror it corresponds to "tick" and when it return to the detector that corresponds to "tock".

By the time the gamma rays work their way out to the solar surface, 3x10 8, they have mostly degraded to light and heat. The diagram shows that there is a limited region of space that we can know about: the region that lies within our past light 3x10 8.

Scientific Notation Decimal to Scientific Notation. Scientific Notation to Decimal. In every field of science, one must have to deal with numbers, the numbers can be in any format like the weight of the earth in kilograms is a very large number or mass of an electron is a very small number. The representation of these types of numbers is not easy. So there is a way known as a scientific notation that we can use to write very large or small numbers in an easier and understandable way. In NASA launched the orbiter to find the data of climate change at mars but after three years the orbiter got lost and investigation on this matter shows that estimate of data was wrong because of two teams transfer their data in different units. The numbers are written in product from like the first number is mantissa and second is the power of 10 exponents:. Here 7 is mantissa and 21 is exponent.

This scientific notation calculator is used to convert scientific notation to other representations of numbers like engineering notation, decimal, and standard form. Scientific notation is a representation of large or small numbers used in numerical and other scientific calculations. It is a way of writing numbers such that the number is greater than or equal to 1 and smaller than The numbers in the example above are in scientific notation. There is always a 10, raised to some power, involved in it. The power of 10 can be positive or negative depending on the nature of the number. To write scientific notation in other forms, you can use the calculator above. Move the decimal point to the left or right equal to the power of 10 times. Meaning here is if the power of 10 is 3, move the decimal point to the right 3 times.

Now answer the following on a separate sheet of paper and check your answers by clicking on "Answers":. We can most easily understand a sequence of events by using a space-time diagram. Simply write the number down as many times as the power to which it is to be raised, and use the rules for multiplication repeatedly. Whenever a problem set is given, you should answer the questions on a separate sheet of paper and then verify your answers by clicking on "Answers. First, write down the number as the number itself times 10 0. Particles follow "straight lines" in this curved space, and we observe their motion as falling toward the massive object. There is a simple procedure for getting a decimal number into the "standard form" for scientific notation:. And don't forget that raising things to powers always takes priority over multiplication and division! This is analagous to the clearing of a fog, so that following this transition light could stream freely through the universe. This can be done because 10 0 equals one, and any number times one equals that number.

The second is the flatness problem: we don't know whether the universe is open or closed, but we do know that it is not very far from flat in either direction. We say that a certain kind of particle "freezes out" at a certain temperature. Quantum theory implies that the universe is an uncertain place. If the number is expressed in words, first write it down as an ordinary decimal number and then convert. And don't forget that raising things to powers always takes priority over multiplication and division! First, write down the number as the number itself times 10 0. Nuclear power plants use nuclear fission: Uranium is split up into lighter nuclei. Multiplication, division, and raising to powers is actually easier. One major transition occured when the universe cooled to the point where free electrons and protons were replaced by neutral hydrogen atoms. In situations where addition and subtraction are mixed with multiplication and division, do the multiplication and division first, then do the addition and subtraction. The expression "10 n ", where n is a whole number, simply means "10 raised to the nth power," or in other words, a number gotten by using 10 as a factor n times:. Second, start moving the decimal point in the coefficient to the right or left. Your proper age is measured by your heartbeat: wherever you go. In the same way, mass causes the whole universe to be curved.
