The first reason is that in the past humans didn't necessarily see the connections between the oceans and thus labelled them that way separating them into 5 oceans and the names stuck to this day.
Secondly, while all the oceans of the world constitute one large Ocean, people need some way to identify each part of it since it is easier to think when we have different categories instead of one large category.
Hope that helped!
Mercury vapor is the answer
Answer:
v = 0.352 m/s
Explanation:
To calculate escape velocity,
( P.E. + K.E ) at the surface of the asteroid = ( P.E. + K.E ) at the infinity
Here infinity is refered as the point wjich does not feel the gravitational potential of the asteroid,
For minimum velocity the K.E at infinity = 0
-GMm/r² +
= 0 + 0
v² = 2GM/r² = 2 × 6.674×10⁻¹¹×7.2×10¹⁶/(8800)²
v = 0.352 m/s
Sunspots occur at two times in the solar cycle corresponding to the "NS" orientation of magnetic poles for a 1/2 cycle and an "SN" orientation for the other half.
