If from a fixed nail in the wall we pull two wires forming a right angle (90 degrees) from which forces of 3 and 4 pounds respectively are made, determine the resultant force graphically on graph paper and then calculate the resultant force using the theorem of Pythagoras.

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.
