The problem you have shown is in scientific notation, in standard notation, you're looking at 34.
Yes. Most programming languages accept scientific notation. Scientific notation is usually considered normalized if there is one digit left of the decimal point; what you write in a constant doesn't need not be normalized; but the end-result of calculations, if shown in scientific notation, will usually be normalized.
That depends on the calculator model. Typically, a calculator would switch to scientific notation when the number is less than 0.001, or greater than can be shown on screen in normal notation.
18094123515000 in scientific notation is 1.8094123515 x 10^13
0.20 = 2 x 10-1 Scientific notation means that the number has to be shown in the format of a x 10b where a is any number greater than or equal to 1 and smaller than 10 and b is any integer
The two numbers shown in a scientific notation are decimals and a 10 with a positive or negative exponent. Example: 2.50 times 10^2= 250 Example2) 2.50 times 10^-4= 0.000250 Hint: if a exponent is a - it will be small, if it is greater than 1 it will be big. 10^0 will be1.
Then you would need lots of digits to write down some numbers, like the diameter of the known Universe in meters, the mass of the Sun in kilometers, the mass of an electron in kilograms, Avogadro's number, etc. This would be very confusing - it is much easier to have the number of digits shown in scientific notation, than having to count them every time.
A+
The phase constant of the oscillation shown in the figure is 180 degrees.
It would be more correct to use "in" than "on". But rather than using "drawing" it might be better to use the word "illustration" or "figure" unless you were referring to an actual drawing as a piece of artwork.
There are two different labeled rays shown in the figure.
