A Spherical Black Body With A Radius Of 12cm Radiates 450 Watt, NTA Abhyas 2022: A spherical black body with a radius of 12cm radiates 450W power at 500K .

A Spherical Black Body With A Radius Of 12cm Radiates 450 Watt, May 7, 2017 · Stefan-Boltzmann law- It states that the total radiant heat power emitted from a surface is proportional to the fourth power of its absolute temperature. Calculation: Radius of the spherical black body, R 1 = 12 cm. If the radius were halved, and the temperature doubled, th Explanation The power radiated by a black body is proportional to the square of its radius and the fourth power of its temperature. ⇒ P = (4 π σ) r 2 T 4 = 450 ………………… (1) Therefore the option (D) is correct. If the radius were halved and the temperature doubled, the power radiated in watt would be :-. Note: To solve such types of questions one should carefully read the statements in the given question and figure out the kind of body that is emitting radiation whether it is black body or not. , Power, P ∝ T 4. Note that the radius is halved and the temperature is doubled. We need to calculate the power radiated in watts. where P and T is the power radiated and temperature respectively. 6vpx, 6okpn0lrf, k0kftzg5, vlqx1on, evlh, bh, cpdl, zhgfn9l, nblio, firbx,
