How should the speed of light be expressed in scientific notation?
Scientific notation is a shorthand way of writing these numbers. The speed of light is approximately 300,000,000 meters per second. This is shortened to 3.0 x 108 m/s, where 8 is the number of zeros that follow the 3.

What is 1 parsec in km in scientific notation?
about 31 trillion kilometers A parsec is equal to about 31 trillion kilometers, or 19 trillion miles in length. Rather than writing all the zeros associated with the number 1 trillion (1,000,000,000,000) we commonly use the written words or scientific notation, which is also called exponential notation.

How do you write 1550000000 in scientific notation?
Like any number written in scientific notation, 15500000 has a significand (sometimes called a mantissa or coefficient) of 1.55 multiplied by the power of ten 10000000 expressed by the base 10 and index 7: 15500000 = 1.55 x 10000000 = 1.55 × 107.
How do you write 6300000000 in scientific notation?
Therefore: 6300000 = 6.3 × 106. This can also be expressed as 6.3 × 10^6 , using the caret symbol, or as 6.3e+6, which is called 6300000 in e-notation, further discussed in the section ahead.
Why is light speed 3×10?
The speed of light is measured to have the same value of c = 3×108 m/s no matter who measures it. Example: If you shoot a bullet forward from an airplane at a speed vb, an observer on the ground would measure its speed to be vb + va where va is the speed of the airplane.
How is the speed of light measured?
The speed of light could then be found by dividing the diameter of the Earth's orbit by the time difference. The Dutch scientist Christiaan Huygens, who first did the arithmetic, found a value for the speed of light equivalent to 131,000 miles per second. The correct value is 186,000 miles per second.
Why is the speed of light 300000 km s?
Re: Why the light travels only a 300,000 kms? there are no rules that limit or set the speed of light. the speed of light is what it is, because that's how fast a Photon travels.. we measured the speed vs our standard measurements, and got the number..
How long is a light year in scientific notation?
A light year is the distance that light can travel in one year. 1 light year = 9,460,000,000,000 km. One light year in scientific notation is expressed as 9.46 × 10¹² km.
