0.095kg is going in a circle on a horizontal frictionless surface. It is held in its orbit by 0.65 s (10%) Problem 1: A puck of mass m = massless string of length L 0.85 m. The puck makes one revolution every t 50% Part (a) What the magnitude of the tension in the string, F, in Newtons, while it spins? 50% Part (b) The string breaks suddenly. How fast does the puck move away, v in m/s?

Which of these statements best explains how the hydrosphere interacts with the atmosphere to affect global climate? mountains block rain clouds and cause changes in global rainfall and evaporation. humans burn fossil fuels to produce greenhouse gases which cause global warming. humans cut down trees which affects the amount of oxygen in different parts of the globe. greenhouse gases, like carbon dioxide, dissolve in oceans and prevent global warming.
