Answer:
0.63m
Explanation:
Volume expansivity = change in volume/original volume×temp change
Volume expansivity p = 3x
p = ∆V/V∆t
x is the linear expansivity
Given
x = 6 x 10^-4
p = 3x
p = 3(6 x 10^-5)
p = 18×10^-5
Volume = 100m³
∆t = 45-10 = 35°C
Required
Change in volume ∆V
Substitute the given values into the formula
18×10^-5 = ∆V/100(35)
18×10^-5 =∆V/3500
∆V = 3500×0.00018
∆V = 0.63m
Hence the increase in volume of the Mercury is 0.63n

Answer:
662 nm
Explanation:
given,
camera lens of n = 1.5
magnesium fluoride n = 1.38
thickness = 120 n m = 120 × 10⁻⁹m
thickness =
wave length = 120× 10⁻⁹ × 4 × 1.38
= 0.662 × 10⁻⁶ m
= 662 nm
hence, the wavelength is equal to 662 nm
Yes i agree with that tbh beciase i think it does do so
