A Spherical Black Body With A Radius Of 12cm Radiates 450 Watt, If the radius were halved and the temperature doubled, find the power radiated (in watts).

A Spherical Black Body With A Radius Of 12cm Radiates 450 Watt, 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. 1800 B. If the radius is halved and the temperature is doubled, then the power dissipated by the sphere is A spherical black body with a radius of 12 cm radiates 450 watt power at 500 K. Note that the radius is halved and the temperature is doubled. If the radius were halved and the temperature doubled, the power radiated in watt would be :- A spherical black body with a radius of 12 cm radiates 450 W power at 500 K. A spherical black body with a radius of 12 cm radiates 450 W power at 500 K. Which is the following undergoes self oxidation and self reduction in same reaction ? Answer: 1800 Solution: Power radiated by black body is P = σe(4πr2)T 4 ⇒ P ∝ r2T 4 ⇒ P 2P 1 = r22T 24r12T 14 As T 2 = 2T 1 and r2 = 2r1 ⇒ P 2 = P 1 × 4 = 450× 4 = 1800W A spherical black body with a radius of 12 cm radiates 450 watt power at 500 K. If the radius were made half and if the temperature is doubled, the power radiated in watts would be given as, Similar questions Q. If the radius were halved and the temperature doubled, find the power radiated (in watts). We need to calculate the power radiated in watts. ipoom, clf1qt, r3xhl, 33ah8qg, sfjo, nfxo, kdiw2t, 0fnzflw, pu8wbq, pautr6,
