C) above, the Earth's core is about the melting point of iron.
Explanation:
1. Height Relatives to reference point, Mass, and strength of the gravitational field it's in
2. Distance in the magnetic field
Answer:
Wavelength
Explanation:
Wavelength is the distance between two corresponding consecutive phases of a waveform. It is usually represented by λ in the mathematical expressions.
A continuous propagating wave repeats its wavelength over the distance.
A wave has crest and trough with respect to time and space.
Wave is defined as a disturbance of any parameter repeated in a cyclic manner over the given time.
