A woman is using a lever to lift a heavy object. The lever consists of a uniform plank of wood pivoted.(There is 2.2m between the woman and the pivot.) The plank is 3.0m long and weighs 200N. (0.8m be
a) 6.023 kilopigs
b) 6.023*10^-6 megapigs
c) 6.023*10^3 kilopigs
d) Both a and c are correct
e) All of the above are correct.-c is correct. Kilo means x1000, and 10³ is also 1000, and 1000x1000 = 1000
