Question

Given that average speed is distance traveled divided by time, determine the values of mm and nn when the time it takes a beam of light to get from the Sun to the Earth (in ss) is written in scientific notation. Note: the speed of light is approximately 3.0××108 m/sm/s.

    Given that average speed is distance traveled divided by time, determine the values of m and n when the time it takes a beam of light to get from the Sun to the Earth (in s) is written in scientific notation. Note: the speed of light is approximately 3.0×108 m/s.

    Answer:

    The  values of  m and  n is    5 and  2  

    Explanation:

    From the question we are told that

       The  speed of light is v = 3.0 *10^{8} \ m/s

       

    Generally the distance between the sun and the earth has a constant value

          d = 1.5*10^{11} \ m

    So the time  taken is mathematically evaluated as

            t = \frac{1.5*10^{11}}{3.0*10^{8}}

             t = 5.0 *10^{2}

    Generally scientific notation is represented as

            m* 10^n

    So comparing the standard representation of scientific notation and the value obtained we see that

         m =  5  and  n=  2
