Explanation:
Answer:
They would be proportional.
Explanation:
Electronegativity and ionization energy go hand in had. The more strongly an atoms pulls electrons to itself (electronegativity) the harder it will be to pick the electrons off (ionization energy). Therefore, the graphs would be proportional.
Answer:
All of these are micronutrients.
Answer:
The wave with the wavelength of 8.82 nm have frequency of 0.340 × 10¹⁷ s⁻¹.
Explanation:
Given data:
Wavelength of x-ray = 8.82 nm
frequency of x-ray = ?
Solution:
speed = Wavelength × frequency
frequency = speed / Wavelength
c = 3 × 10⁸ m/s
f = c/ λ
f = 3 × 10⁸ m/s /8.82 × 10⁻⁹m
f = 0.340 × 10¹⁷ s⁻¹
The wave with the wavelength of 8.82 nm have frequency of 0.340 × 10¹⁷ s⁻¹.
