Explanation:Hope this helps you XD ✌️Carry on ur learning !!
they are made of gases.
they have a spherical shape.
they make energy through fusion.
a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
