Gymnast nellie weighs 300 n. she hangs from two
non-vertical ropes, as shown in figures 2.11 and
2.12 in chapter 2. (a) how large is the resultant
of the rope tensions in figure 2.11? (b) how large
is the resultant of the rope tension in figure 2.12?
(c) in which of these two figures is the horizontal
component of the rope tension greater? explain
how you can tell.

The bubbles in a carbonated soft drink are produced when carbonic acid decomposes to form carbon dioxide and water. in a closed system, this equilibrium exists as why does a carbonated soft drink lose carbonation when the container is left open? a.water evaporates, which favors the formation of h2co3. b.pressure decreases, which favors the formation of h2co3. c.the open container warms up, which causes more gas to escape. d.co2is removed, which favors the formation of h2co3.
