Question

Describe and correct the error. The speed of light, often denoted by the variable c, is 2.998 times 10 meters per second. Because the distance light travels in one year is so large, in 1838 the German astronomer and mathematician Friedrich Bessel coined the term "light-year" to represent this distance. Bessel first used this term when he announced that the distance to the star 61 Cygni was 103 light years. Given that there are 3600 seconds in an hour, 24hours in a day, and approximately 365.24 days in a year, what is the distance to 61 Cygni in meters? Give your answer in scientific notation with 3 decimal places.

Explanation / Answer

Dear student, the error is in seond third and fourth consecutive step of the problem which you may shortout as follows-

x-2/x4.(y3)2

= x-2/x4.(y6)

= 1/x6.(y6)
