Power Equation?? 1. The problem statement, all variables and given/known data An ice cube is placed in a microwave oven. Suppose the oven delivers 135 W of power to the ice cube and that it takes 33200 Joules to melt it. How long does it take for the ice cube to melt? 2. Relevant equations P = W / T 3. The attempt at a solution Ok so I know the answer but this is confusing me... A unit of Power is J/second. So if we rearrange the equation and solve for T in minutes it would be. T = W / P, T = 135 / 33200 which doesn't give us the right equation to solve it... Instead it would be 33200 / 135 / 60 = 4.1 minutes, But why when I rearrange the equation doesn't it make sense?
