Final answer:
The provided information discusses the energy density of lithium-ion batteries versus gasoline and the use of scientific notation in aerospace, but does not include the minimum flight weight of the Challenger 650.
Step-by-step explanation:
The Challenger 650 is a business jet designed and manufactured by Bombardier Aerospace. The question regarding the minimum flight weight of the Challenger 650 is specific to the field of aeronautical engineering. However, the provided passage does not include the exact minimum flight weight for the Challenger 650. Instead, the passage discusses the energy density of lithium-ion batteries versus gasoline and the challenges of using batteries as a primary power source for commercial airliners like the Boeing 737 and Boeing 777-200ER.
For example, it is mentioned that the best lithium-ion batteries store about 0.17 kcal/g, which is significantly less than the energy density of gasoline, which is around 11 kcal/g. This comparison highlights the difficulties in replacing traditional jet fuel with batteries in current commercial aircraft due to their weight and energy storage capabilities. Moreover, the passage uses scientific notation to present the maximum takeoff weight of a Boeing 777-200ER, emphasizing the importance of scientific notation in representing large or small numbers in the field of aerospace.
In conclusion, while the passage is useful for understanding the considerations related to aircraft weight and energy requirements, it does not provide the specific information needed to answer the student's question about the minimum flight weight of the Challenger 650.
