Jawaban:Penjelasan:Gunakan rumus Stefan-Boltzmann:P = σ × A × T^4Dengan:σ = 5,67 × 10^-8 W/m²K⁴A = 30 mm² = 3,0 × 10^-5 m²T = 437°C = 710 KP = (5,67 × 10^-8) × (3,0 × 10^-5) × (710)^4P ≈ 0,43 WattNB: ^ adalah pangkat jadi kalau ketemu seperti ini itu artinya pangkatcontoh : 10^-8 berarti 10 pangkat -8
