Answer:
The refractive index of the plastic, n₂ is between 0.73696 and 0.85034
Explanation:
Here we have;
Snell's law which is the relationship of the refractive index of light in two media. The law, in mathematical terms, states the ratio of the refractive index of light between two media is inversely proportional to the ratio of the sine of the angle of incidence to the sine of the angle of refraction.
That is the sine of the angle of incidence and the sine of the angle of refraction are inversely proportional.
0.79365 ± 0.05669
If θ₂ = Angle inside the plastic object and
θ₁ = Angle outside the plastic object
n₁ = Refractive index of air outside the plastic = 1
n₂ = Refractive index of the plastic
Therefore, , which gives;
∴ 0.73696 ≤ n₂ ≤ 0.85034.
The refractive index of the plastic, n₂ is between 0.73696 and 0.85034.
Answer:
The answer is thermal energy
Explanation:
Answer:
Force = 10.244 Newtons
b) No of oscillations = 0.88
Explanation:
Since the block executes SHM we can write it's position as function of time as
ω is the natural frequency of the system
A is the amplitude of the system
Thus accleration of the block
Thus using the given values at t= 3.50 sec we can calculate the acceleration as
thus force can be calculated using newtons second law as
b)
Now no of oscillations can be obtained as
no of oscillations in 3.50 seconds = 3.50/3.976 = 0.88
