- <em><u>Mechanical advantage of levers depends on how far away each are from the fulcrum. </u></em>
- <em><u>The mechanical advantage of a lever is increased when either the effort is moved further away from the fulcrum or the load is shifted closer to the fulcrum, or both.</u></em>
Answer: warm and rainy
A warm front is the transition zone which develop in a region where warm air replaces the cold air. The air behind the warm front is warmer than air in the front. When the warm front reaches a region with colder air, the cold air gets warm and more humid. Warm front brings changes in weather condition of a region.
