Answer: E) all of the above
Explanation:
Frequency is the number of vibrations in one second. It is also defined as the number of crests that pass a point in a given time.
The frequency and the wavelength has an inverse relationship.
Frequency is measured in cycles per second or Hertz(Hz).
The relationship between wavelength and frequency of the wave follows the equation:

where,
= frequency of the wave
c = speed of light
= wavelength of the wave
Thus all the given statements are true.
Answer:
B: leaving metal outside in the rain until rust forms an it's surface
Answer:
65 m/s
Explanation:
v=v0+at <=> v = 11 + 12 t ∧ t = 4.5 s <=> v = 11 + 12×4.5 <=> v = 65 m/s
