According to Pascal's Law, if a lever used in a basic jack provides a mechanical advantage of 10:1 and the operator presses down on the pilot cylinder with a force of 10 pounds, how many pounds of force would the lever deliver?

Explanation:
The main idea here is that mechanical advantage multiplies your input force. With a 10:1 ratio, the output force is ten times the input force (assuming ideal conditions). So pressing the pilot cylinder with 10 pounds yields 10 × 10 = 100 pounds at the lever. The system trades force for distance, meaning the input moves a longer distance than the output. The other options would only make sense if the advantage were different or if there were no amplification at all.
