B. Nonmetallic
C. Metallic
D. Nonmetallic
E. Metallic
Answer:
C
Explanation:
The substance would be classified as neutral, so C.
Answer:
4.52 x 10¹⁴ cycles/s
Explanation:
From c = f·λ => f = c/λ = (3.0 x 10⁸ m/s)/(6.63 x 10⁻⁷m) = 4.52 x 10¹⁴ cycles/s.
f = frequency = ?
λ = wavelength = 6.63 x 10⁻⁷ meter
c = speed of light in vacuum = 3.0 x 10⁸ meters/s
The answer should be C. Technology is the application of the knowledge gained by science.
