A spherical weather balloon is filled with hydrogen until itsradius is 2.40 m. Its total mass including theinstruments it carries is 13.0 kg.
(a) Find the buoyant force acting on the balloon, assuming thedensity of air is 1.29 kg/m3. answer in kN(b) What is the net force acting on the balloon and its instrumentsafter the balloon is released from the ground? answer in kN(c) Why does the radius of the balloon tend to increase as it risesto higher altitude?
Because the external pressure decreasesor increases with increasing altitude.
