Answer:
False. The Northern Lights are actually the result of collisions between gaseous particles in the Earth's atmosphere with charged particles released from the sun's atmosphere.
Explanation:
<h2>Succession </h2>
Explanation:
Succession is a phenomenon in which older communities are replaced by advanced and newer communities
- Primary succession is the one in which succession occurs at newer area where none of the community previously evolved
- Secondary succession is the one in which the substrate has already been prepared by the older communities so that the newer community which will arrive grow faster that is why secondary succession has faster pace
- Glacial retreats leave behind nothing but bare rock as they retreat from an area, leaving barren land from which primary succession can occur which enables scientist to study plant succession

Answer:
λ = 37 nm
Radiation is in the ultra violet region.
Explanation:
Given data:
Energy of photon = 5.44 × 10 ⁻¹⁸ J
Wavelength of photon = ?
Solution:
E = h.c / λ
λ = h. c/ E
λ = 6.63× 10⁻³⁴m² kg/s × 3×10⁸ m/s / 5.44 × 10 ⁻¹⁸ Kg m²/s²
λ = 19.89 × 10⁻²⁶ kg. m³ /s² / 5.44 × 10 ⁻¹⁸ Kg m²/s²
λ = 3.7 × 10⁻⁸ m
m to nm conversion.
λ = 3.7 × 10⁻⁸m ×10⁹ nm / 1m
λ = 37 nm
Radiation is in the ultra violet region because the rage of UV is 1 nm - 400 nm.
