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:
Explanation:
Displacement is the change in the position of an object.
Abigail runs a complete lap around the track, which is 400 meters. Even though she ran 400 meters, she has <u>no displacement.</u> If she starts and ends at the same spot, there is no change in position.
Gabi runs a 50 meter dash in a straight line. Gabi has <u>50 meters of displacement</u>. She runs in a straight line and is 50 meters away from where she began.
While Abigail ran the farther distance, <u>Gabi had the greater displacement.</u>
The spring's work output while it is not extended is 5 J.
<h3>What is The Hooke's law ?</h3>
According to Hooke's law, as long as the elastic limit is not exceeded, the extension of a particular material is directly proportional to the force applied. Hence, we must be aware of that F = Ke
F = Applied force
Force constant is K.
Extension = e
F = applied force
Force constant is K.
Extension = e
Using the graph
K = F/e
F = 200N
E equals 5 cm or 5 * 10-2 m
K = 200N/ 5 * 10^-2 m
K = 4000 N/m
Now;
Work = 1/2Ke^2
Work = 0.5 * 4000 N/m * (5 * 10^-2 m)^2
Work = 5 J

Hello.
The formula for Power is Work divided by Time; however, we do not have our value for Work - yet.
To find for the Work inputted, we need to use its formula: Force * Distance.
Let's multiply our Force by our Distance. Remember that our Force is always measured in Newtons (N), and our Distance is measured by Meters (M).
35,000 * 25 = 875,000 J (Unit for Work is "J" or "Joules")
Now that we have the value for Work, let's apply it to our Power formula.
P = 875,000 / 45; 19,444.44~
The Power required to lift the girder is 1944.44~ W (Unit for Power is "W" or "Watts").
I hope this helps!
