Answer: A difference in properties between two interacting systems as explained below.
Explanation: Planetary differentiation is the process of separation of different parts of a planetary body as a result of their physical or chemical behavior.
Causes for Physical Differentiation:
1. Melting and crystallization of source rock.
2. Differences in densities
3. Thermal diffusion
4. Collision of large bodies
Chemical Differentiation accounts for differences in chemical compositions of different materials.
The differentiation, or organization, of the Earth into layers led to the formation of a core, a crust, and eventually continents. The light elements were driven from the interior to form an ocean and atmosphere.
Explanation:
they would formulate a new hypothesis with the same dependent variable but a different independent variable as a virginal hypothesis .
Answer:
rock will hit the ground at the same time.
Explanation:
given,
Jan throws rock vertically downward with some initial velocity(v).
Len throw rock at an angle of 30° with initial velocity(2 v) twice than the Jan
to find whose rock will hit the ground first.
it is given that rock is identical
now,
vertical component of velocity of the rock
= v₂ sin θ
= v₂ sin 30°
=
= v
hence the vertical velocity of the Len is same as that of Jan so the rock will hit the ground at the same time.
