If the object is completely submerged at that time, then the volume of
the full object is 652 cm³.
If only part of the object is in the water, then the volume of the part that's
in the water is 652 cm³, but we have no idea what its full volume is.
I have a strong hunch that if you read through pages 184 to 187 in the book,
you'll find each of these statements there, with no blank spaces.
1. negative
2. static
3. electrons
4. repel
5. attract
6. static
7. electric current
8. closed or complete
9. open
Answer: 557nm
Explanation:
Visible light has been known to have its wavelengths in the range between 400 to 700 nanometres (nm), or 4*10^-7 to 7*10^-7 m. This wavelength is between infrared and ultraviolet. Infrared has longer wavelengths and while on the other hand ultraviolet has shorter wavelengths. The wavelength of visible light has a frequency of approximately 430 to 750 terahertz (THz).
tanΦ= 0.0039/4 = 9.75*10^-4
Φ= tan^-1 (9.75*10^-4)
Φ= 0.056
λ= (5.7*10^-4) * sin 0.056
λ= 5.57*10^-7m
λ= 557nm
