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.
Answer:
L = 94.2 ft
n ≈ 5
Explanation:
d = 500 ft
R = 15 ft
The pony walks in one ride around the circle:
L = 2*π*R = 2*3.14*15 ft = 30*π ft = 94.2 ft (One ride around the circle).
In order to determine how many times (n) can the pony give a ride before it needs a drink, we can apply
n = d / L = 500 ft / 94.2 ft = 5.308 ≈ 5
Answer:
The dog catches up with the man 6.1714m later.
Explanation:
The first thing to take into account is the speed formula. It is , where v is speed, d is distance and t is time. From this formula, we can get the distance formula by finding d, it is
Now, the distance equation for the man would be:
The distance equation for the dog would be obtained by the same way with just a little detail. The dog takes off running 1.8s after the man did. So, in the equation we must subtract 1.8 from t.
For a better understanding, at t=1.8 the dog must be in d=0. Let's verify:
Now, for finding how far they have each traveled when the dog catches up with the man we must match the equations of each one.
The result obtained previously means that the dog catches up with the man 3.8571s after the man started running.
That value is used in the man's distance equation.
Finally, the dog catches up with the man 6.1714m later.
Answer:
0 J
Explanation:
Because W=F*D, and the sphere's total distance is 0m, the work done is automatically 0 J.
The focus is the actual point of rock breakage or movement. the focus is usually located far below the surface of the Earth. The epicenter is the point on the surface of the Earth directly above the focus.
