Answer:
Ken Mattingly suggests that they get the required amps from the Lunar exertion module.
Step-by-step explanation:
The flight Apollo 13 was a space mission that was intended to go to the moon. But with an unforeseen explosion in the spacecraft, the mission to the moon was halted and the main work began on bringing the men safely back to earth.
But due to the explosion, the re-entry was impossible. The spacecraft had lost a lot of oxygen and electrical power and had increased levels of CO2 in it. en Mattingly was assigned to help the men in the astronauts work on the simulator so that they can gain re-entry back to earth's atmosphere or they will be lost forever in space. So, when they needed to get the 4 amps of electricity down for the re-entry program, Ken suggests that they get it from the LEM (Lunar Exertion Module).
