Which choice best describes data in the graph description that support Meng and colleagues' conclusion? Weight of Three Aerial Robots: - Ultra-Fast Robot Hand: 505 grams - Permanent Magnet Hand: 295 grams - Yale Model T: 490 grams Aerial robots vary considerably in their holding force; the Ultra-Fast Robot Hand, for example, has a holding force of 56 newtons, more than twice that of the Permanent Magnet Hand and more than four times that of the Yale Model T. Since an aerial robot must lift its own weight along with its cargo, engineer Jiawei Meng and colleagues used a ratio of each robot's holding force to the robot's weight to calculate payload capacity, with higher ratios corresponding to greater capacity, concluding that the Ultra-Fast Robot Hand has a higher payload capacity than the Yale Model T.
- 1The Ultra-Fast Robot Hand weighs only slightly more than the Yale Model T does.✓
- 2The Yale Model T has a lower holding force than the Permanent Magnet Hand despite weighing more.
- 3The Ultra-Fast Robot Hand and the Yale Model T each weigh more than the Permanent Magnet Hand does.
- 4The Ultra-Fast Robot Hand and the Yale Model T each weigh more than 450 grams.
Correct answer
The Ultra-Fast Robot Hand weighs only slightly more than the Yale Model T does.
