Answer:
6.7 ×
Explanation:
Initial P = Final P
(1.8 × 0) + (.0075 × 0) = (1.8 × x) + (.0075 × 16)
-.12 + 1.8x
x = .0067

Answer:
a) The minimum thickness of the oil slick at the spot is 313 nm
b) the minimum thickness be now will be 125 nm
Explanation:
Given the data in the question;
a) The index of refraction of the oil is 1.20. What is the minimum thickness of the oil slick at that spot?
t = λ/2n
given that; wavelength λ = 750 nm and index of refraction of the oil n = 1.20
we substitute
t = 750 / 2(1.20)
t = 750 / 2.4
t = 312.5 ≈ 313 nm
Therefore, The minimum thickness of the oil slick at the spot is 313 nm
b)
Suppose the oil had an index of refraction of 1.50. What would the minimum thickness be now?
minimum thickness of the oil slick at the spot will be;
t = λ/4n
given that; wavelength λ = 750 nm and index of refraction of the oil n = 1.50
we substitute
t = 750 / 4(1.50)
t = 750 / 6
t = 125 nm
Therefore, the minimum thickness be now will be 125 nm
Answer:
The magnitude of the electric field and direction of electric field are and 75.36°.
Explanation:
Given that,
First charge
Second charge
Distance between two corners r= 50 cm
We need to calculate the electric field due to other charges at one corner
For E₁
Using formula of electric field
Put the value into the formula
For E₂,
Using formula of electric field
Put the value into the formula
We need to calculate the horizontal electric field
We need to calculate the vertical electric field
We need to calculate the net electric field
Put the value into the formula
We need to calculate the direction of electric field
Using formula of direction
Hence, The magnitude of the electric field and direction of electric field are and 75.36°.
