Final answer:The task requires determining the final temperature of water which has absorbed heat transferred from heated gold and silver cubes. This is solved by applying basic physics principles, including energy conservation and heating calculations involving specific heat capacity and mass.Explanation:This is a typical problem where the concept ofthermal equilibriumbeing reached in a system is used, involving changes in physical properties such as temperature and energy transfer. The conservation of energy, an important principle in physics says, energy lost by warm body = energy gained by cold bodies during a heat transfer process.In this case, the cubes of gold and silver will lose energy to the water in order to achieve thermal equilibrium. The lost heat (q) can be calculated using the formula q=mcΔT, where m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. First, one would need to calculate the mass of the silver and gold cubes using the given density and dimensions: mass=density x volume. Then, calculate how much heat each cube loses as it cools down to the final temperature and sum the heats up. This just the amount of energy the water has to gain, meaning the total heat gained by water is equal to the total heat lost by the gold and silver. From that you can calculate the final temperature (T f) of the water using the equation q=mc(T f-T _initial).Learn more about Thermal Equilibrium here:brainly.com/question/29419074#SPJ12...
