Ahot-air balloon consists of a basket hanging beneath a large envelope filled with hot air. a typical hot-air balloon has a total mass of 534 kg, including passengers in its basket, and holds 2.77 ✕ 103 m3 of hot air in its envelope. if the ambient air density is 1.23 kg/m3, determine the density (in kg/m3) of hot air inside the envelope when the balloon is neutrally buoyant. neglect the volume of air displaced by the basket and passengers. hint kg/m

  = 1,037 kg/m³

Explanation:

This is a problem with the Archimedes principle that states that the thrust on a body is equal to the weight of the dislodged fluid.

Let's write Newton's second law for this balance

     B- W- = 0

     B = W +  

Where W is the weight of the basket and the passengers and Wair is the weight of the air inside the balloon

The thrust is

     B = g V

We replace

    g V = mg + g V

    = ( V - m) / V

    = - m / V

    = -m / V

  = 1.23 - 534 /2.77 103

  = 1,037 kg/m³

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
