Question

Гвоздь поместили в мензурку с керосином. До погружения гвоздя керосина в мензурке было 30 мл, после погружения стало 60 мл. Чему равна Архимедова сила, действующая на гвоздь.

Answer 1

Ответ:

Объем гвоздя V=V2-V1=40-40=20 мл=2*10^-5 м3

Fa=7100*10*2*10^-5=0,142 H

Answer 2

Calculation of Archimedes' Force

To calculate the Archimedes' force acting on the nail, we need to determine the buoyant force exerted by the kerosene on the nail. The buoyant force is equal to the weight of the fluid displaced by the submerged part of the nail.

Given the initial volume of kerosene in the measuring cylinder before the nail was submerged was 30 ml, and the final volume after the nail was submerged was 60 ml, we can determine the volume of kerosene displaced by the nail.

The change in volume of the kerosene is 60 ml - 30 ml = 30 ml.

Now, we can calculate the Archimedes' force using the formula:

Archimedes' Force = Density of Fluid x Volume of Fluid Displaced x Acceleration due to Gravity

Since the density of kerosene is not provided, we cannot calculate the exact value of the Archimedes' force without this information. The density of kerosene is required to determine the weight of the fluid displaced.

Please provide the density of kerosene, and I will be able to calculate the Archimedes' force for you.
