Your friend argues that holding a heavy weight in the air requires a lot of work. According to physics, how much work does it require to hold a 500 N block a distance of 2.0 m above the ground?
It requires 500 J of work.
It requires 500 N of work.
It requires 500 x 2 = 1000 J of work.
It doesn't require any work to hold a block above the ground because there the block isn't being pushed through any distance.

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.
