Given that cosø = 5/13, determine sin ø tanø

0.0000000065m = 6.5 * 10⁻⁹ or 6.5E-9

Step-by-step explanation:

Given;

Wavelength of X-ray = 0.0000000065 meters

i.e. λ = 0.0000000065 m

The question asks to convert the wavelength to scientific notation;

To do this, we have to follow the steps below

Write the non-zero digits, placing a decimal after the first non-zero digit. : 6.5Then, count the number of digits that needs to be moved from the beginning of the decimal to get to where the decimal is now. If you move the decimal to the left, then your power is positive: -9So, 0.0000000065m = 6.5 * 10⁻⁹It can also be represented as 6.5E-9
