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.
It is given that total amount of oxygen in the reactants is 4 atoms to balance this chemical equation it is necessary that total number of reactant molecules should equal the total number of products.
Explanation:
The coefficients are found by counting each individual atom and atom numbers are same in reactants and products.
Without balancing the equation the formation is H2O and O2. The total number of oxygen in the product side is 3. Hence to balance this equation multiply H2O by 2 and O2 by 1. Thus the total of 4 O2 atoms will be formed on the product side.
Therefore, We can say that the coefficient 2 should be placed in front of water and and 1 in front of oxygen.
Answer:
I= 1.616 KA
Explanation:
Given that
L = 2.2 m
N= 1300 turns
r= 30 cm
B= 1.2 T
We know that magnetic field in solenoid given as
Now by putting the values
I= 1616.03 A
So the current is 1616.03 A.
I= 1.616 KA
