Final answer:
The AH-64D Apache has a maximum gross weight of 23,000 pounds, and the AH-64E model has a maximum of 23,500 pounds. These weights can be expressed in scientific notation as well, which is a common practice in engineering for representing measurements.
Step-by-step explanation:
The AH-64D/E Apache is a twin-engine attack helicopter operated by the U.S. Army. When discussing its maximum gross weight, we are referring to the maximum weight at which the aircraft is certified to take off. This weight includes the weight of the aircraft itself, fuel, payload, and any other equipment on board.
The maximum gross weight for the AH-64D Apache is 23,000 pounds, whereas the upgraded AH-64E model has a slightly higher maximum gross weight at 23,500 pounds. These figures can be represented in different numerical formats. For example, the weight of the AH-64D can be written in scientific notation as 1.04 × 104 kilograms (since 1 pound is approximately equal to 0.453592 kilograms).
Understanding how to represent measurements in various ways, such as decimal form and scientific notation, is important in engineering, as well as many other fields of study. As shown with the maximum takeoff weight of a Boeing 777-200ER airliner being 298,000 kilograms or 2.98 × 105 kg, converting and understanding these notations are useful skills for precise communication of measurements.
