A. 4
B. 1.5
C. 0.25
D. 8

Answer 1

The mechanical advantage of an inclined plane with a slope length of 9 m and a height of 3.5 m is 2.57. The mechanical advantage of a wedge with a thickness of 0.5 m and a length of 2 m is 4.

Step-by-step explanation:

The mechanical advantage (MA) of an inclined plane is calculated by dividing the length of the slope (the distance along the incline) by the height of the incline. For the inclined plane with a slope length of 9 m and a height of 3.5 m, the mechanical advantage would be 9 m / 3.5 m = 2.57. Therefore, the correct answer is A. 2.57.

For a wedge, the mechanical advantage is determined by dividing the length of the wedge by its thickness. Thus, with a thickness of 0.5 m and a length of 2 m, the mechanical advantage of the wedge would be 2 m / 0.5 m = 4. The correct answer is A. 4.
