Explanation:
The given data is as follows.
Spring constant (k) = 78 N/m, 
Mass of block (m) = 0.50 kg
According to the formula of energy conservation,
mgh sin 
h = 
= 
= 0.64 m
Thus, we can conclude that the distance traveled by the block is 0.64 m.
Answer:
the answer is 3600 kilometers
The story that fits the graph is; he elevator moves up, is stationary for a while, then moves down at a slower rate.
<h3>What is a position time graph?</h3>
The term position time graph shows us how the position of the object is changing with time. The position in this case has to do with the exact point in space where the object can be found. We have here an elevator that could be found at various points.
We now have to turn to the graph and see how the graph can be able to give a description of the motion of the elevator. If we look at the position time graph, it tends to move up and then remain at a point for some time before it moves down.
Based on the analysis that we have made above, we can now look out for any of the stories that fits the description that we have just made here.

Answer:
X2 - X2'=3.24×10⁻⁴m
Explanation:
Given Data
λ1=730nm=
λ2=640nm
d=0.61 mm
D=1.1 m
Distance of the second bright fringe from the central fringe is given by
Xn = = D x n x2 λ / d
X2 = 2 D λ1 / d
X2' = 2 D λ2 / d
Separation between the second bright fringes of the two wavelengths ( the separation between the second order fringes ) is ,
X2 - X2' = 2 D ( λ1 - λ2 ) / d
X2 - X2'= {2 x 1. 1 (730×10^-9 - 640×10^-9) }/ 0.61 x 10 ^-3
X2 - X2'=3.24×10⁻⁴m
