nope. the equation i originally posted is the correct one. Can you help me solve that one? I am pretty confused.

Homework Statement A) To= 35 °C find α And β B) determine the temp in which this material becomes a super conductor as predicted by the equation below. ρ=ρ0(1 + α(T-To) + β(T-To)^2)To= 35 C. ρo=2.5e-8Ω m T1= 0 C. ρ1=2.346e-8Ω m T2= 100 C. ρ2=3.036e-8Ω mHomework Equations ρ=ρ0(1 +...

Since, power = energy/time, is the energy the q-value from q=mcΔT?

Homework Statement A pot containing 15 kg of water at 30 C is heated until all the water is at 90 C, by placing a resistor (having resistance R=930Ω) in the water and running a current through it. What current must be placed through the resistor if the 15 kg of water is raised from 30 C to...
