ball (weight = 4800 n) is supported by a boom, which maybe assumed
to be uniform and has a weight of 3600 n. as the drawingshows, a
support cable runs from the top of the boom to thetractor. the
angle between the support cable and the horizontal is32 degrees,
and the angle between the boom and the horizontal is 48degrees.
find (a) the tension in the support cable and (b) themagnitude of
the force exerted on the lower end of the boom by thehinge at point

The air in an automobile tire with a volume of 2.60 ft3 is at 70°f and 21 psig. determine the amount of air that must be added to raise the pressure to the recommended value of 30 psig. assume the atmospheric pressure to be 14.6 psia and the temperature and the volume to remain constant. the gas constant of air is ru = 53.34ft⋅lbflbm⋅r(1 psia144 lbf/ft2) = 0.3704 psia⋅ft3lbm⋅r the amount of air that must be added to raise the pressure is lbm

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.
