One point will be X1,Y1 and the other will be X2,Y2. It does not matter which is which except that X1 and Y1 have to be the same point and X2 and Y2 have to be the same point. For example, let's say you were given (2,3) and (6,8). No matter which point is X1,Y1 and the other is X2,Y2, the slope will still be 5/4.
The rise is the change in y from one point to the other. The run would be the change in x from one point to the other.
net force on Maze during his sliding downwards motion
now we will have
now to find the acceleration we will have
now to find the speed after 4 s is given by kinematics
here we know that
so Maze speed after 4 s will be 16.22 m/s

Final Length 
a)
Generally the rotation with the greater speed is
b)
Generally the equation for centripetal acceleration at 8.16 is mathematically given by
c)
At 6.35 rev/s
Answer:
The evidence that supports the wave particle nature of light as a wave is:
"Light reflects when it hits a surface."
Explanation:
Light exhibit wave-particle duality. This means, in some cases the properties of light are just like a wave and in other cases it behaves as particles.
The properties like reflection or refraction from a surface are attributed as properties of waves. The phenomena of interference and diffraction also fall in this category.
Therefore, from the given options, the only option that supports the evidence of light as a wave is "Light reflects when it hits a surface", as reflection is entirely the property of a wave.
