Si un jugador de fútbol corre detrás de su oponente 50 m al norte. luego se da la vuelta y lo persigue 20 m al sur, ¿cuál es su distancia?​

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

You can melt ice by applying pressure because the solid/liquid line has a slope.
