Answer:
The correct answer is b. Differences in Path Lenght
Explanation:
In this area of knowledge, there two main ways of referring to Path Lenght:
1. The total distance an object travels from a starting point, without considering trajectory.
2. When talking about wavelength, because this relates to light and how it travels throughout different mediums. This concept is used in calculating constructive and destructive interference of waves, and is responsible for seeing different shades of tea color.
Hope this helps!
Answer:
stronger forces between particles means the substance boils at a higher temperature.

Criteria and Limitations—In this section, please list at least three criteria that must be met by your train design. Also include any limitations that could prevent it from getting its cargo to the station.
Criteria Limitations One steam engine Two separate hills One cargo box Missing tracks Stack items across or atop each other Weight
Design Ideas—Pros and Cons:In this section, describe three design ideas you have for your train. List at least one pro (a positive) and one con (a negative) for each design option
Description of Train Design One Wheels first with two springs underneath each wheel, the panda cargo in the middle with the steam engine in the front, and two sets of helium balloons.
Answer: The coefficient of friction is 0.35
Explanation:
We can write the friction force as:
F = N*μ
Where N is the normal force between the refrigerator and the ground, as the full weight of the refrigerator is acting on the ground, the normal force will be exactly equal to the weight of the refrigerator, then:
N = 650N
And μ is the coefficient of friction.
And for this case, the force is 230N, then we have:
F = N*μ
230N = 650N*μ
(230N/650N) = μ = 0.35
Notice that the distance did not matter for this calculation.
