масса оболочки воздушного шара составляет 200 кг.При надувании его гелием шар принимает объем 1000 м в кубе,при этом плотность гелия в шаре 0,18 кг м в кубе.Плотность воздуха 1,29 кг м в кубе,какую максимальную массу груза может поднять этот шар?
M=200 Кг  V=1000 м3  p1=0,18 кг/м3  m2=1,29 кг/м3  m - ?
Fa=M*g+m*g+p1*g*V     Fa=p2*g*V
m=p2*V-M-p1*V=1290-200-180=910 кг

Calculation of the Maximum Lift Capacity of the Balloon

To calculate the maximum lift capacity of the balloon, we need to consider the buoyant force acting on the balloon. The buoyant force is equal to the weight of the air displaced by the balloon. In this case, the balloon is filled with helium, which has a lower density than air. Therefore, the buoyant force will be greater than the weight of the balloon itself.

Let's calculate the maximum lift capacity step by step:

1. Calculate the weight of the air displaced by the balloon: - The volume of the balloon is given as 1000 m^3. - The density of air is 1.29 kg/m^3. - Therefore, the weight of the air displaced by the balloon is 1000 m^3 * 1.29 kg/m^3 = 1290 kg.

2. Calculate the weight of the helium in the balloon: - The density of helium in the balloon is given as 0.18 kg/m^3. - Therefore, the weight of the helium in the balloon is 1000 m^3 * 0.18 kg/m^3 = 180 kg.

3. Calculate the net buoyant force: - The net buoyant force is the difference between the weight of the air displaced by the balloon and the weight of the helium in the balloon. - Net buoyant force = weight of the air displaced - weight of the helium - Net buoyant force = 1290 kg - 180 kg = 1110 kg.

Therefore, the maximum lift capacity of the balloon is 1110 kg. This means that the balloon can lift a maximum mass of 1110 kg, including its own mass of 200 kg, when filled with helium.

Please note that this calculation assumes ideal conditions and does not take into account other factors such as the weight of the balloon material, the weight of any payload attached to the balloon, or the effects of temperature and pressure variations on the density of air and helium.
