Answer:
the answer is 4/9
Step-by-step explanation:
1/3= 3/9
The minimum thickness of the book would simply be the sum
of the thickness of the two cover pages and all the pages in between. That is:
minimum thickness = 0.9 mm * 2 + 0.13 mm * 400
<span>minimum thickness = 53.8 mm</span>
Some are said more than once but they is 10 different choices together so it’s be ‘1/10 probability’
From the attached graphic:
e = c*h/wavelength therefore,
wavelength = c*h / e
wavelength = 299,792,458 * 6.62606957e-34 / 3.38x10^-19
wavelength = 5.8771e-7 meters
I think the answer is 24. Let me know if I helped!
