Aspherical balloon is made from a material whose mass is 2.70 kg. the thickness of the material is negligible compared to the 1.55 m radius of the balloon. the balloon is filled with helium (he) at a temperature of 290 k and just floats in air, neither rising nor falling. the density of the surrounding air is 1.19 kg/m³ and the molar mass of helium is 4.0026×10-3 kg/mol. find the absolute pressure of the helium gas.

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
