How does the length to height ratio (the IMA) of trial 1 compare to trial 2? Why is the actual mechanical advantage less than the ideal mechanical advantage in each of the trials?

If a machine was 100% efficient, how would the AMA compare to the IMA?

Give at least three examples from everyday life where an inclined plane is used to reduce the effort force needed to accomplish a task.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
