Answer:
λ = 547.96 nm
Explanation:
given,
thickness of soap bubble = 103 nm
refractive index of thin film = 1.33
using formula of constructive interference
t is thickness of the medium
n is refractive index
m = 0,1,2...
now,
at m = 0
λ = 547.96 nm
at m = 1
λ = 182.65 nm
the only visible light enhanced by the thin film is of wavelength
λ = 547.96 nm
Thats is instantaneous bc it’s in the moment
1.
The energy stored in a capacitor is given by
where
C is the capacitance
V is the potential difference across the capacitor
In this problem, we have
is the capacitance of the capacitor
is the p.d. across the capacitor
Solving the equation, we find the energy stored:
2.
The average power delivered to the coils is equal to the ratio between the energy released and the time taken:
where
is the energy released by the capacitor
is the time taken
Substituting into the formula, we find

Answer:
m/min
Explanation:
You have to use the volume of a cone, which is:
where r is the radius of the base and h is the height.
In this case, r=5 and h=10. The radius can be written as r=h/2
Replacing it in the equation:
(I)
The rate of the volume is the derivate of volume respect time, therefore you have to perform the implicit differentiation of the previous equation and equal the result to 3.14 m³/min
Replacing dV/dt= 3.14, h=7.5 and solving for dh/dt, which represents how fast the level is rising:
Multiplying by 16/225π both sides:
m/min
