I uploaded both info sources because I don't know which one is for my questions. please solve both questions in the last picture.

High Power Lithium Ion ANR266507h A/235ystems hithium-ion rechargeable ANR266507w] cell is copoble of very high power, lang Project planning data Constant current discharge Project planning data constant power discharge 10: For a lithium-ion battery, energy and performance values are to be determined. The right course of the internal resistance Ri and the open circuit voltage OCV was measured depending on the state of charge SOC. In addition, a capacity K was determined. The following operating limits are also known from the data sheet: (Umax etc.] a) During operation, only the state of charge range x%=
