tatiyna

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 = \frac{b}{T}

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

ANTONII [103]

Answer:

option (b)

Explanation:

B = 0.7 x 10^-4 T

v = 940 km/h = 940 x 5 / 18 = 261.11 m /s

l = 60 m

Th emotional emf is given by

e = B v l

e = 0.7 x 10^-4 x 261.11 x 60 = 1.096 V

e = 1.1 V
