A 65.0-g object connected to a spring with a force constant of 40.0 N/m oscillates with an amplitude of 8.00 cm on a frictionless, horizontal surface. (a) Find the total energy of the system.

(b) Find the speed of the object when its position is 1.30 cm. (Let 0 cm be the position of equilibrium.)

(c) Find the kinetic energy when its position is 3.00 cm.
mJ

(d) Find the potential energy when its position is 3.00 cm.

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.
