Answer:
Option D
Explanation:
The answer is option D or "the distance over which the force is applied." Since basic machinery is created to lessen the work for us humans reducing the strength of the force means that the distance which where the force is needed to be applied needs to be increased. Increasing the distance for the machine makes it all around more efficient. One of the most common examples of basic machinery is a rake. When using a rake, you do not need to apply as much force into it to make the rake efficient. If you increase the distance on where you are raking, then the amount you are raking increases, which means it's all-around efficiency increases.
Hope this helps.
Answer:
1. Mass of the Earth is 5.97219 × 10^24 kg
2. Radius of the Earth is 6,371 km
3. Acceleration due to gravity on the surface of the Earth is 9.81 m/s^2
4. Acceleration due to gravity on the surface of the moon is 1.625 m/s^2
Explanation:
The mass and radius of Earth are <u>5.97219 × 10^24 kg</u> ME and <u>6,371 km</u> RE, respectively. The mass and radius of the Moon are approximately 186ME and 27RE, respectively. The acceleration due to gravity on the surface of Earth is <u>9.81 m/s^2</u> . The acceleration due to gravity on the surface of the Moon is most nearly <u>1.625 m/s^2</u>
