Answer:
Angle of refraction.
Explanation:
Refraction is simply a change in direction of light rays as it enters into another medium.
In the diagram given above, θ2 is simply the angle of refraction showing us that the light ray has changed direction as it moves from one medium to another medium.
The answer is periosteum. Hope this helps!
Answer:
Explanation:
So we want the speed to go from 25 m/s to 0 m/s in 170 m, but the time needs to incorporate the reaction time, so the slowing down will not start until .68 s pass. Or, in other words, the train will travel an extra 25 m/s * .68 s = 17 m. This means, instead of 170 m to slow down it has 153. Hopefully that makes sense. With this information we can use the equation vf^2-vi^2=2ad. If that equation is unfamiliar you need to get a better handle on your physics equations.
Anyway, let's plug in.
vf = 0 m/s
vi = 25 m/s
a is what we're trying to find
d = 153 m
vf^2-vi^2=2ad
a = (vf^2-vi^2)/(2d)
Can you handle figuring it out from there? or if there is something you don't understand let me know.
Answer:
All of the following would be true statements about natural substances in this philosophy EXCEPT:___
b) a substance is always composed of other substances ad infinitum
Explanation:
To provide an answer to the question, we analyse each option as follows
a) a substance is in full being when its potentiality has been actualized
According to Aristotle, every thing consist of potential which is natural for them to attempt to develop their potential and a substance with actualizes potential is fully developed.
b) a substance is always composed of other substances ad infinitum
For Aristotelian metaphysician, a semicircle is described by the circle of which it forms a part, because if we describe a circle by a semi circle and a semicircle by a quarter of a circle then we have ad infinitum number of definitions. Therefore, according to Aristotelian metaphysics, a substance is not always composed of other substances ad infinitum.
For example, the statement a man is a man is true but if analysed from the constituents will lead to contradiction.
c) a substance is analyzable into form and matter
According to Metaphysics, without form matter would be without properties does not exist and every matter is with form.
