Earth and Venus both presumably had similar gases outgassed from their volcanoes. Briefly explain how their atmospheres ended up so different
What will be an ideal response?
On Venus, water and carbon dioxide remained in the atmosphere. Over time, ultraviolet light split the water molecules and the hydrogen escaped to space. Thus, Venus has no more water today and an atmosphere thick with carbon dioxide. On Earth, water condensed to rain and eventually formed the oceans. Carbon dioxide was absorbed in the oceans and is now locked up in carbonate rocks. Thus, most of the water on Earth remains in the oceans, and most of the carbon dioxide is in rocks, leaving a much thinner atmosphere than that of Venus.

What would happen if the battery connections were suddenly reversed?
Jewelry is often manufactured by electroplating an expensive metal such as gold over a cheaper metal. A setup for this process can be sketched as follows: A) The ring would continue to electroplate with gold. B) Gold ions in solution would get reduced and settle to the bottom of the container. C) Gold ions in solution would begin to electroplate onto the gold electrode. D) All electrolysis would stop.
A ballerina spins initially at 1.5 revolutions/second when her arms are extended. She then draws in her arms to her body and her moment of inertia becomes 0.88 kg- and her angular speed increases to 4.0 rev/s
Determine her initial moment of inertia.
