a certain gamma ray has an approximate wavelength of 0.0000000000069 meter. write this number (in m) in scientific notation. \n×10 m

Answer

Explanation:

Step1: Identify non - zero digits

The non - zero digits in the number (0.0000000000069) are (6.9).

Step2: Determine the exponent of 10

The decimal point needs to be moved 12 places to the right to get a number between 1 and 10. Since we are moving the decimal point to the right for a number less than 1, the exponent of 10 is negative. So the exponent is (- 12).

Answer:

(6.9\times10^{-12}) m
