Final answer:
The maximum zero fuel weight for the Challenger 650 is not provided in the question; it requires technical specifications of the aircraft. The reference focuses on comparisons between battery and gasoline energies and their impact on aircraft performance.
Step-by-step explanation:
The Challenger 650's maximum zero fuel weight is not explicitly provided in the question. Instead, the provided reference information focuses on energy storage in batteries versus gasoline and their implications on aircraft performance. This indicates the importance of fuel efficiency and overall weight management in aircraft design, critical aspects of aeronautical engineering. However, to directly answer the student's question about the Challenger 650, the maximum zero fuel weight would have to be looked up from the aircraft's specific technical specifications, which are not included in the given information. Understanding scientific notation and unit conversions, as seen when expressing the Boeing 777-200ER's maximum takeoff weight, is essential in engineering calculations.
