PET and fMRI scans have revealed that the brain's activity during REM sleep is: Select one: A. very similar to its activity during both wakefulness and NREM slow-wave sleep. B. at its lowest level of activity during the night's sleep. C. distinctly different from its activity during either wakefulness or NREM slow-wave sleep. D. greatly increased in both the frontal lobes and the primary visual cortex.

a. formula: f=ma or f/m=a

10,000n/1,267kg≈7.9m/

b. formula: a= and s=d/t

speed= 394.6/15

s=26.3m/s

a=

a=1.75m/

c. 7.9-1.75=difference of 6.15m/

d. the force that most likely caused this difference is friction forces

the answer is solomon northrup. he was a free-born african american, abolitionist and professional violinist that was drugged, kidnapped and sold as slave in 1841 and remained in captivity until 1853 where he regained his freedom with the of the then-governor of new york, washington hunt. he wrote and published his memoirs "twelve years a slave" in 1853, and in this text, he tells the story of his escape thru one of louisiana's swamps (the great pacoudrie swamp) in which he ended up covered in green slime from crossing the surface of the dead water.
