A 5.0-m radius playground merry-go-round with a moment of inertia of 2000 kg ? m2 is rotating freely with an angular speed of 1.0 rad/s
Two people, each of mass 60 kg, are standing right outside the edge of the merry-go-round and suddenly step onto the edge with negligible speed relative to the ground. What is the angular speed of the merry-go-round right after the two people have stepped on? A) 0.20 rad/s B) 0.40 rad/s C) 0.60 rad/s D) 0.80 rad/s E) 0.67 rad/s
Cells at the top of a tree have a higher concentration of sugars than cells at the bottom. How might this fact assist a tree in moving water upward from its roots?
A) Cells with high concentrations of sugar are more dense. As these cells migrate downwards, cells containing fresh water are able to migrate upwards. B) Water is pushed upwards by osmostic pressure. C) It doesn't. In fact, water makes it to the top of a tree because that is where the water molecules are being evaporated. D) Fresh water is drawn upwards to the sugar containing cells by way of dipole-dipole molecular interactions.

a. 0. b. 0.012 N, East. c. 0.012 N, West. d. 0.30 N, West. e. 300 N, East.
