Question

Тело имеет массу 80кг и обЪем 0,1метров квадратных бкдет ли плавать в бензине

Answer 1

плотность тела r=m/v=80/0.1=800 кг/м3

плотности тела и бензина равны.

тело будет плавать в бензине

сила тяжести P=mg=80*10=800H

сила архимеда A=rgV=800*10*0.1=800 H

Силы уравновешивают друг гдруга

Answer 2

Can a body with a mass of 80 kg and a volume of 0.1 square meters float in gasoline?

To determine if a body with a mass of 80 kg and a volume of 0.1 square meters can float in gasoline, we need to consider the density of the body and the density of gasoline.

The density of an object is calculated by dividing its mass by its volume: density = mass/volume.

Let's calculate the density of the body: - Mass = 80 kg - Volume = 0.1 square meters

Density of the body = Mass/Volume = 80 kg / 0.1 square meters = 800 kg/m^3

Now, we need to compare the density of the body with the density of gasoline. If the density of the body is less than the density of gasoline, the body will float. Otherwise, it will sink.

The density of gasoline is approximately 700-800 kg/m^3.

Since the density of the body (800 kg/m^3) is greater than the density of gasoline (700-800 kg/m^3), the body will sink in gasoline.

Therefore, a body with a mass of 80 kg and a volume of 0.1 square meters will not float in gasoline.

I hope this answers your question! Let me know if you have any further queries.
