Find Displacement and Distance
displacement ...
north is 700+400+100 =1200m n
south=1200m
1200-1200=0
east is 300+300=600m
west is 600m
600-600=0
back at dtart. displ zero
distance is 700+ 300m + 400 m + 600m + 1200m + 300m + 100m = 3600m
Answer:
Wind
Explanation:
I had this question on one of my tests, and I got it right
Answer:600N/m
Explanation: Given ;
Applied force(F) = 180N
Total extension (l) = 30cm =0.30m
Spring constant(K) =?
From Hooke's law
F= kx
therefore k= F/x
k = 180N/0.3m
600N/m
Answer:
Medium A -> medium C -> medium B
Explanation:
Refraction is defined a s the change in the direction of light rays as it moves from one medium to another. The speed of the light in this media depends on the nature and the refractive indices of the media.
Light has the tendency to travel faster through a medium with low refractive index rather than high refractive index.
Comparing this medias based on the above conclusion
Medium A has index of refraction 1.3; medium
B has index of refraction 1.4 and medium
C has index of refraction 1.35
The light will travel faster in medium A since it have the lowest refractive index followed by medium C then medium B.
Ranking of the media in accordance the time it takes for light to travel through these layers are as shown
Medium A -> medium C -> medium B
