Awheel 1.0 m in radius rotates with an angular acceleration of 4.0rad/s2 . (a) if the wheel’s initial angular velocity is 2.0 rad/s, what is its angular velocity after 10 s? (b) through what angle does it rotate in the 10-s interval? (c) what are the tangential speed and acceleration of a point on the rim of the wheel at the end of the 10-s interval?

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.
