The best object to show the Earth's true appearance is something round and smooth. Since the earth is only slightly oblate, it doesn't matter based on its size, and you would use a pool ball as the perfect scale model, because it is very round and smooth.

Answer:
★The second law of refraction
The ratio of sine of angle of incidence to the sine of angle of refraction is a constant for a light of given colour and for a given pair of media. This law is also called Snell's law of refraction. If 'i' is the angle of incidence and 'r' is the angle of refraction then, Sin i/Sin r = constant
This constant value is called the refractive index of the second medium with respect to the first.
From the graph, the average acceleration between 5.0 s and 8.0 s is 2.33 ms^2.
<h3>What is acceleration?</h3>
The term acceleration has to do with the change in velocity with time. We can see that the graph shown is a graph of velocity against time, the slope of the graph is the acceleration.
Thus, the average acceleration between 5.0 s and 8.0 s can be read off from the graph as 20 m/s - 13m//8.0 s - 5.0 s = 2.33 ms^2.
