Answer:
n = 1.5
Explanation:
The speed of light in vacuum is 300000000 m/s
The speed of light in glass is 200000000 m/s
We need to find the refractive index of the glass.
We know that, the ratio of speed of light in vacuum to the speed of light in medium is equal to refractive index of the medium.
![n=\dfrac{300000000 }{200000000 }\\\\=1.5](https://tex.z-dn.net/?f=n%3D%5Cdfrac%7B300000000%20%7D%7B200000000%20%7D%5C%5C%5C%5C%3D1.5)
So, the refractive index of the glass is 1.5.
Answer:
181276.802 m
Explanation:
The computation of the horizontal range of the shell is shown below:
As we know that
range = u × usin2θ ÷ g
where,
u = 1600 m/s
θ = 68
g=9.81
- Now
Put these values to the above formula
So, the value of the horizontal range of the shell is
R = 181276.802 m
= 181276.802 m
We simply applied the above formula and the same is to be considered
Answer:
a. -2.07 m/sc^2
b. 9.204
c. 4.25 seconds
Explanation:
a. The computation of puck's acceleration is shown below:-
![V^2-Vo^2 = 2as\\\\ (6.20)^2 - (15)^2 = 2 a 45.0\\\\](https://tex.z-dn.net/?f=V%5E2-Vo%5E2%20%3D%202as%5C%5C%5C%5C%20%286.20%29%5E2%20-%20%2815%29%5E2%20%3D%202%20a%2045.0%5C%5C%5C%5C)
38.44 - 225 = 90a
= -2.07 m/sc^2
b. The computation of velocity is shown below:-
![v = Vo + at](https://tex.z-dn.net/?f=v%20%3D%20Vo%20%2B%20at)
= 15 - (2.07) × 2.80
= 9.204
c. The computation of long which take to travel is shown below:-
= (v - u) ÷ a
= (6.2 - 15) ÷ (-2.07)
= 4.25 seconds
We simply applied the above formulas so that the correct answers could be come
