Acart of mass 250 g is place on a frictionless horizontal air track. a spring having a spring constant of 9.5 n/m is attached between the cart and the left end o f the track. if the cart is displaced 4.5 cm from its equilibrium position, find: a) the period at which it oscillates.[1.0 s] b) its maximum speed.[0.28 m/s] c) its speed when it is located 2.0 cm from its equilibrium position.[0.25 m/s]

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.
