This is one article of a series on using DNA for genealogical research. There are several. types of DNA tests offered for genealogical purposes. Researchers must understand that. only like tests can be compared: Y-DNA to Y-DNA, mitochondrial DNA (mtDNA) to. mtDNA, and autosomal DNA (atDNA) to autosomal DNA. To use DNA to solve a. problem, an understanding of DNA inheritance and the limits of the evidence is paramount. This article covers atDNA.
The speed of light is about 186,000 miles or 300,000 kilometers per second. So, in one year light travels a distance of about 5,880,000,000,000 miles or 9,460,000,000,000 kilometers or 63,240 A.U.. This distance is 1 light-year.For example, the nearest star to us is about 4.3 light-years away.he speed of light is about 186,000 miles or 300,000 kilometers per second. So, in one year light travels a distance of about 5,880,000,000,000 miles or 9,460,000,000,000 kilometers or 63,240 A.U.. This distance is 1 light-year.
Question: If the speed of light is 3x10^8 m/s, what is the s... If the speed of light is 3x10^8 m/s, what is the speed in m.p.h and Ft/s? Would appreciate the work.
