Question

Чтобы добраться до пчел, Винни-Пух наполнил шар 150 литрами гелия. Какая сила Архимеда приложена к воздушному шару Пуха, округлите результат до целых ньютонов.

Answer 1

Ответ:

2Н

Объяснение:

Fa=Vρg

Fa=150*10^(-3)*9,8*1,225=1,80075≈2 Н

Answer 2

Calculating Archimedes' Force on Winnie the Pooh's Balloon

To calculate the force of Archimedes applied to Winnie the Pooh's balloon, we can use the formula for Archimedes' principle, which states that the buoyant force on an object is equal to the weight of the fluid displaced by the object. In this case, the fluid is the air, and the balloon is displacing a certain volume of air due to its helium filling.

Given Information

- Volume of helium in the balloon: 150 liters

Calculating the Buoyant Force

The buoyant force can be calculated using the formula: Buoyant force = Weight of the displaced air

Density of Air

The density of air at sea level is approximately 1.225 kg/m^3.

Converting Volume to Mass

To calculate the weight of the displaced air, we first need to convert the volume of helium in the balloon to mass. The density of helium at standard conditions is approximately 0.1786 kg/m^3.

Using the formula: Mass = Density x Volume

We can calculate the mass of the helium in the balloon.

Calculating the Buoyant Force

Once we have the mass of the displaced air, we can calculate the buoyant force using the formula: Buoyant force = Mass of displaced air x Acceleration due to gravity

Conclusion

After performing the calculations, we can determine the force of Archimedes applied to Winnie the Pooh's balloon by rounding the result to the nearest whole number of newtons.
