Fatty acids are mostly composed of chains of carbon and hydrogen. Fatty acids without double bonds are "saturated" with hydrogen. When a fatty acid has one double bond, hydrogen is released therefore the fatty acid is "monounsaturated". When a fatty acid has two or more double bonds, then the fatty acid is "polyunsaturated". Unsaturated fatty acids are usually takes in the form of oils as they are liquid in room temperature (in contrast to saturated fatty acids which are solid in room temperature). Unsaturated fatty acids are usually found in plant based fats such as oils. Therefore the answer to this question is sunflower oil.
The answer is mechanical weathering
It's basically a wave that moves back and forth at regular speed through matter. because of that it transfers energy through a medium (matter). however the movement of the wave is limited because of this but it can still move over long distances. so because of this these types of waves don't move far from their original point or Equilibrium position. in short think of throwing a pebble into water and seeing the little ripples from it, that's a mechanical wave.
