Answer:
The gravitational force between them increases by a factor of 4
Explanation:
Gravitational force is a force of attraction between two objects with masses M and m which are separated by a distance R. It is given mathematically as:
Fg = GMm/R²
Where G = Gravitational constant.
If the distance between their centers, R, decreases by a factor of 2, then it means the new distance between their centers is:
r = R/2
Hence,the gravitational force becomes:
Fg = GMm/r²
Fg = GMm/(R/2)²
Fg = GMm/(R²/4)
Fg = 4GMm/R²
Hence,the gravitational force increases by a factor of 4.
Answer:
442.75862 nm
Explanation:
m = Order
n = Refractive index
= Wavelength
We have the relation of thickness and wavelength given by
The consecutive spectral line is given by
So,
and
Dividing the wavelengths we get
The film thickness of oil is 442.75862 nm
