Sierra did 500 j of work to move her couch. if she exerts 250 n of force on the couch, how far did she move it? (work: w = fd) a. 0.5 m b. 2 m c. 250 m d. 750 m

for 8 am not sure maybe yes?

for 9 if it is asking if the male is more or less it would be less

hope i even just a little : )

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects
