The Bantu migrations are most closely associated with the spreading of cultures in Africa
The bantu migrations refer to the Original African People which located in western Africa which migrated across the Current African continent, spreading their cultures along the way.
Foremost of these are magma viscosity, gas loss and external properties such as conduit geometry. Ultimately, these parameters control the speed at which magmas ascend, decompress and outgas en route to the surface, and thus determine eruptive style and evolution.
Answer:
2200
Explanation:
The Hubble law states that
v= H × d
where, v = speed, H = Humble constant, d = distance.
Thus
v=22 km/(sec/million ly)×100 million ly
=2200 km/sec.
