Answer:
Explanation:
thickness of oil t = 200 nm
index of refraction μ = 1.5
For transmitted light :---
path difference = 2μ t
For constructive interference
path difference = n λ , λ is wavelength of light
2μ t = n λ
λ = 2μ t / n
For longest λ , n = 1
λ = 2μ t
= 2 x 1.5 x 200 nm
= 600 nm
Wavelength in water
= 600 / refractive index of water
= 600 / 1.33
= 451.1 nm Ans

Answer : if connected series, 20 ohms
And if connected parallel, answer will be less than 20 ohms
When resistors are wired in series, the total circuit resistance increases because each resistor contributes opposition to the circuit's current flow. Therefore if a 10 ohm resistor is placed in series with another 10 ohm resistor, the total resistance contributed by the two resistors is 20 ohms.
Answer:
A ball moving through the air.
Explanation:
The ball has momentum which is a form of kinetic energy.
I don't know if that is correct, but I hope it helps!!!!
Answer:
Speed of light
Explanation:
The famous Einstein's equation is:
where
E is the energy
m is the mass
is the speed of light
In this equation, Einstein summarized the following fact: mass can be converted into energy, and the amount of energy released in such a process is given by the equation.
An example of application of this equation is the nuclear fusion process. In a nuclear fusion, two lighter nuclei combine into a heavier nucleus. However, the mass of the heavier nucleus is slightly less than the sum of the masses of the two original nuclei: some of the mass of the original nuclei has been converted into energy, accorging to the previous equation.
