- | The defibrillator must be able to deliver 360 J to Johnny 5 in order to stabilize him. Can you fix the instrument and save him? | + | The paper sheets are 0.5 m wide, 2 m in length, and vary in thickness (2 mm, 1 mm, 500 μm, 50 μm, 1 μm, 0.5 μm). The aluminum sheets are 0.80 m in length, 0.5 m wide, and 0.3 mm in thickness. The stock room also has a high voltage power supply of 30 kV. Your device must be able to deliver a rapid jolt of 360 J to I.A.N. in order to restart him. Can you put something together to get him working and save the day? |
