Liquid oxygen is stored in a thin-walled, spherical container 0.75 m in diameter, which is enclosed within a second thin-walled,
spherical container 1.1 m in diameter. The opaque, diffuse, gray container surfaces have an emissivity of 0.05 and are separated by an evacuated space.
a. If the outer surface is at 280 K and the inner surface is at 90 K, what is the mass rate of oxygen lost due to evaporation?

Answer:
The impedance of the circuit depends on the angular frequency of the voltage source.
Explanation:
- In a electric circuit, the magnitude of the impedance, is given by the following expression:
where R = Resistance
Xl = Inductive reactance = ω*L
Xc = Capacitive Reactance = 1/ωC
and ω = angular frequency of the voltage source.
- So, it can be seen that the impedance depends on the value of the constants R,L and C, and on the angular frequency ω.
