A block of metal with a mass of 3kg and an initial temperature of 75°C is placed into a 1kg mass of water at a temperature of 0°C the metal has a specific heat capacity is 650J/ kg •C in the water has a specific heat capacity of 4186J/kg •K what is the final temperature of the metal as a metal reaches thermal equilibrium with the water? 

"induction" is the process of charging an object without touching it.hope my answer has you : )

Iwould have to say sorry i can't elaborate more. hope this though!

The correct answer should be b let me know if i’m wrong

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
