6. Your head of powertrain has found a battery cell with excellent specifications and yet cheap. He decides upon a 142s2p accumulator configuration using the cells with a capacity of 5.8 Ah. The manufacturer specifies an internal impedance of 1.5 mOhm. However, after a while you notice the cells are of horrible quality and their real capacity varies significantly leading to an unbalanced accumulator.

He performed experiements to find an approximation of the cells SoC relation to their open-circuit voltage (EMF) as shown in the following figure:

Assume due to imbalance, exactly half of the accumulators cells are at 40% SoC and half at 80% SoC. What current will be drawn at the maximum allowed power usage? Give answer in Amps to nearest whole number

A metal piece heated to θ_1,M=1000∘C with a mass of M_M=6.5 kg was cooled in a completely heat-insulated iron container filled with water. The mass of the water in the container is M_W=10 kg and the mass of the container is M_B=2 kg. The initial temperatures of the water and the container were the same and amounted to θ_1,W=10∘C. After complete thermal equilibrium between the immersed metal piece, the water, and the container, a temperature of θ2=80∘C was established.
What is the average specific heat capacity of the metal piece cc in the temperature range between 80∘C and 1000∘C?

Input the result in kJ/(kg*K), round to 3 decimal numbers sperated by a point (example: 0.136).
