A shotput ball is thrown upwards from the top of a tower with initial velocity “i”. The velocity just before it touches the ground was “3i”. In terms of “i”, the height of the tower can be written as (a) 4i2/g

(b) 2i2/g

(d) 4i4/g

(c) 2i2 g

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.
