WebMar 17, 2024 · Step-by-step explanation: Given that M is directly proportional to r² then the equation relating them is. M = kr² ← k is the constant of proportionality. To find k use the condition when r = 2 , M = 14. k = = =. M = r² ← equation of proportion. When M = 224, then. 224 = r² ← multiply both sides by 2. 7r² = 448 ( divide both sides by 7 ) WebThe surface area is proportional to the wire radius, r. So T₀=kP/r = k I² ( ρ / πr² ) /r = k ρ I² / πr³ or I² = πr³ T₀ / (k ρ ) where T₀ is the fusing temperature.
