An aluminium sphere with a mass of 4.2 kg and an initial temperature of 250°C is placed in a closed, thermally Isolated container with 30 kg water water - 4 185kg 1.c '). Determine the final/equilibrium temperature if the initial temperature of the water is 14 C.
A. 20.9°C
B. 132.0°C
C. 6.7°C
D. 26.3°C

Answerthe force between the charges will be  f/9 (one-ninth of force f)explanationcoulomb's law relates the magnitudes  two point charges q₁ and q₂, the distance, r, between the charges, and the electrostatic force, f, between the two charges:     k represents coulomb's constant, k = 8.99×10⁹ n·m²/c².note that if we have r = 3r, then
