Explanation:
refractive index = speed of light in vacuum / speed of light in medium
light travels at a speed of 3.0 x 10^8 m/s in vacuum
refractive index = 3.0 x 10^8 / 2.0 x 10^8
refractive index = 1.5
hope this helps, please mark it
As science being dynamic many things will change and due to this changes many things and theories will be new to us. the model of the atom is not weak, it is just developing as time progress because in the early times it is not fully understood because of the lack of technology to study, what scientist do is just filling the knowledge gap of the previous studies.
Answer:
B
Explanation:
It would be diffrent if on a downward slope but assuming your going straight it would be the smallest student.
Answer:
3469.788 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
First rocket
Second rocket
When this will collide the total distance they would have covered would be 6000 m.
Hence at 13.72 seconds they will collide assuming they are launched at the same time.
The second rocket would have gone 3469.788 m when they collide
