Question

Воздушный шар состоит из оболочки ,гондолы для пассажиров и газовой горелки для нагрева воздуха внутри оболочки ,Масса газовой горелки 30кг. ,что на 150кг меньше массы гондолы и на 20кг меньше массы оболочки .какова масса воздушного шара?

Answer 1

ВоздушныйШар = Оболочка+Гондола+ГазоваяГорелка
ГГ (по условиям задачи) 30 кг
Г на 150 кг тяжелее ГГ, т.е. 30+150= 180 кг
О на 20 кг тяжелее ГГ, т.е. 30+20= 50 кг
ВШ = 50+180+30= 260 кг

Answer 2

Calculation of the Mass of the Hot Air Balloon

To calculate the mass of the hot air balloon, we need to consider the given information. Let's break it down step by step:

1. The gas burner has a mass of 30 kg. 2. The mass of the gas burner is 150 kg less than the mass of the gondola. 3. The mass of the gas burner is 20 kg less than the mass of the envelope (the outer shell of the balloon).

Let's assume the mass of the gondola is G kg and the mass of the envelope is E kg.

According to the given information, we can set up the following equations:

1. The mass of the gas burner is 150 kg less than the mass of the gondola: 30 kg = G kg - 150 kg.

2. The mass of the gas burner is 20 kg less than the mass of the envelope: 30 kg = E kg - 20 kg.

To find the mass of the hot air balloon, we need to determine the values of G and E.

Let's solve the equations:

1. From equation 1, we can isolate G: G kg = 30 kg + 150 kg.

Simplifying, we get: G kg = 180 kg.

2. From equation 2, we can isolate E: E kg = 30 kg + 20 kg.

Simplifying, we get: E kg = 50 kg.

Now that we have the values of G and E, we can calculate the mass of the hot air balloon by adding the masses of the gondola, envelope, and gas burner:

Mass of the hot air balloon = G kg + E kg + 30 kg.

Substituting the values we found earlier:

Mass of the hot air balloon = 180 kg + 50 kg + 30 kg.

Simplifying, we get:

Mass of the hot air balloon = 260 kg.

Therefore, the mass of the hot air balloon is 260 kg.

Please note that the above calculations are based on the given information and assumptions made.
