More than half of the fatty acids in the Eranthis seed oil consist of the unusual fatty acid 22:2n-6 (see Problem 2). Draw the structure of this fatty acid. For your answer, use the following guidelines: 1. Do not show the hydrogens for any secondary carbon atoms. 2. Do show the hydrogens for any primary carbons. 3. Do not abbreviate any functional groups. 4. Show the unionized form of all functional groups.

Which statement is true? a) the work done to lift an object 6 meters is greater than the gravitational potential energy it gains. b) the work required to push an object is less than the work required to pull an object the same distance. c) the work required to raise an object to a height is equal to the gravitational potential energy the object gains. d) the work done against gravity to lift an object straight up is greater than the work required to roll it up a ramp.
