4X10/10=4
0.4 = 4x10-1
The sum would be 2.3x10-4 x 4x10-4 which 9.2x10-8
How can you use 2x10 to find 4x10
The pH of a 0.020 M nitric acid solution would be approximately 1.7. This is because nitric acid is a strong acid and completely dissociates in water to release H+ ions, making the solution acidic.
They can all be multiplied by a certain number to equal 40. such as 4x10= 40 5x8= 40. hope this helps!

The frequency is the reciprocal of the period; in this case, divide 1 / 4x10-7.
wavelength=velocity/frequency (v/f). wavelength=(3x10/4x10)=30/40=.75 meters
