The wavelength at which Earth’s emitted radiation is maximum is ______ at which the wavelength of the Sun’s emitted radiation pe
1 answer:
Answer:
inversely proportional to the temperature
Explanation:
Wein's displacement law states the wavelength at which Earth’s emitted radiation is maximum <u>is inversely proportional to the temperature</u> at which the wavelength of the Sun’s emitted radiation peaks.
λmax
where,
λmax is the maximum wavelength
b is a constant of proportionality called Wien's displacement constant (b = 2.897 × 10⁻³ m.K)
T is the absolute temperature in kelvins

Answer:
Capacitive Reactance is 4 times of resistance
Solution:
As per the question:
R =
where
R = resistance
f = fixed frequency
Now,
For a parallel plate capacitor, capacitance, C:
where
x = separation between the parallel plates
Thus
C ∝
Now, if the distance reduces to one-third:
Capacitance becomes 3 times of the initial capacitace, i.e., x' = 3x, then C' = 3C and hence Current, I becomes 3I.
Also,
Also,
Z ∝ I
Therefore,
Solving the above eqn:
