Which of the following statements regarding the Brake System is false?

Which of the following statements is false regarding the difference between Lead-based batteries, Nickel-based batteries and Lithium-based batteries?

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

You would like to drink a cup of very hot coffee with milk early in the morning, but you
are in a hurry and have only 5 minutes until you have to leave for work. At which time
after brewing should you add the cold milk to the coffee and stir in order to decrease the
temperature of the mixture as much as possible:
a) 0 minutes (immediately),
b) 2 minutes, or
c) 4 minutes?
Suppose that the stirring can be done instantaneously and that you need the last one
minute for drinking.

brew temperature C = 80 ◦C, temperature of milk = M = 10 ◦C, room temperature
0 = 20 ◦C, volume of coffee VC = 300 ml, volume of milk VM = 100 ml, specific heat
capacity of coffee cC = 4180 J/(kgK), specific heat capacity of milk cM = 3500 J/(kgK).
