What is the number of significant figures in the number 0.07020?
4 significant figures. once put in scientific notation you will see 2.057 X 10^-2 You will ignore the last zero since it is to the farthest right past the decimal and not necessary.

If a neutron star has a radius of 10 km and rotates 642 times a second what is the speed of the surface at the neutron star's equator in terms of the speed of light?
The Radius of the Star is 10 KM. Now we need to find the diameter. Circumference equals pi times the Diameter. That is twice the Radius, which is 20. Now we need to get the Diameter. We multiply the diameter by pi. 20 times 3.1416. 20 * 3.1416 = 62.838. Now we multiply the circumference in kilometers by the speed. 62.832 * 642 = 40,338. Now we take the speed of light, 299,997 per second and divide it into the speed of a point on the equator of our star going 40,338 kilometers per second. 40338 / 299997 = 0.1345
Why does light go in the speed of 300000000 meter per second?
Because a photon is massless. Since photons are massless, by the laws of physics all massless objects MUST travel at the speed of light.E=MC^2 "E" is Energy, "M" is Mass, and "C" is the speed of light squared or multiplied by its self.===========================================Another contributor tried to respond to the same question:Strange as it may seem, the speed of light was accurately predicted long before there wasany way to measure it. The prediction falls out naturally from the Physics and Math ofwave motion.In the equation for a wave, a constant appears in one of the terms, and the speed ofthe wave is the square root of the reciprocal of that constant.When you take Maxwell's four equations of electricity and magnetism, and massage themin such a way as to derive the equation of the electromagnetic wave that they wouldproduce, the constant in that particular place in the equation is the product of thevacuum permittivity of space ... 8.854188 x 10-12 ... and the magnetic permeabilityof space ... 1.256637 x 10-6 . Now watch closely as I handle these numbers, withnothing up my sleeve:The product is (8.854188 x 10-12) x (1.256637 x 10-6) = 1.11265 x 10-17 .The reciprocal of that number is 8.987552 x 1016 ,and the square root of that number, which should be the speed of the wave, is299,792,462 meters per second ...only 4 m/s different from the official, internationally accepted number !Admittedly, this still doesn't answer your question of "why", but your question is now"Why are the vacuum permittivity and the magnetic permeability of free space bothexactly the numbers that they are ?"We hope you consider this to be some progress; but if you've simply lost all interestby now, we'll understand.A third response:The speed of light is 300 000 000 m/s because we, as humans, defined what is 1 meter and what is 1 second. The speed of light itself is just a fundamental constant, a fact of this universe. It just "is."In some branches of physics, the speed of light is just defined as 1 distance/time.If you understand special relativity, consider what would happen if the speed of light were say, 10 m/s.

How many significant figures will the product of 0.1400 and 6.02 and 1023 have?
To determine the number of significant figures in the product of 0.1400, 6.02, and (10^{23}), we need to identify the significant figures in each number. The number 0.1400 has four significant figures, 6.02 has three significant figures, and (10^{23}) has one significant figure (as it is a power of ten). The product will have the same number of significant figures as the term with the least significant figures, which is 6.02 with three significant figures. Therefore, the final product will have three significant figures.
What is a 12 10 20.5 1.00 from least to greatest number of significant figures?
The numbers 12, 10, 20.5, and 1.00 have different significant figures: 12 and 10 each have two significant figures, 20.5 has three significant figures, and 1.00 has four significant figures. When ordered from least to greatest number of significant figures, the sequence is 12 (2), 10 (2), 20.5 (3), and 1.00 (4). Thus, the order from least to greatest is: 12, 10, 20.5, 1.00.
