Суретте білеушелердің массасы мен көлемдері бірдей, үстел үстіне білеушелер кай жағдайда ең аз қысым түседі? A) Ең

The first question is asking in which case the density and volume of a substance remain the same when it is weighed on different scales.

To determine this, we need to understand the concept of density and volume. Density is the mass of a substance per unit volume. In other words, it tells us how much mass is present in a given volume. Volume, on the other hand, is the amount of space occupied by a substance.

When we weigh a substance on different scales, we are essentially measuring its mass. If the mass remains the same, it means that the same amount of substance is present regardless of the scale used.

Now, let’s analyze the possible options:

A) In all cases, the mass remains the same: This option suggests that the mass of the substance will always be the same, regardless of the scale used. This is not possible because different scales can have different levels of accuracy and precision, which can result in slight variations in the measured mass.

B) In the worst case, the mass is obtained: This option suggests that the worst case scenario is when the mass is obtained. However, this does not provide a clear answer to the question.

C) Nobody has the same mass: This option suggests that nobody has the same mass, which is not relevant to the question.

D) In all cases, the masses are the same: This option suggests that the masses will always be the same, regardless of the scale used. This is the most plausible answer because it implies that the substance is equally distributed on both scales, resulting in the same mass measurement.

Based on the analysis above, the most suitable answer to the first question is:

D) In all cases, the masses are the same

Now, let’s move on to the second question:

The second question is asking at what level the oil, which is poured into the third container, will be. In order to determine this, we need to compare the densities of the substances involved.

The density of a substance is determined by dividing the mass of the substance by its volume. In this case, we are given the densities of water (ρсу= 1000 kg/m3), oil (ρмұнай = 900 kg/m3), and gasoline (ρбензин = 710 kg/m3).

To determine the level at which the oil will be in the third container, we need to compare the density of oil with the densities of water and gasoline.

The density of water is greater than the density of oil (1000 kg/m3 > 900 kg/m3), which means that water is denser than oil. This implies that oil will float on top of water.

Similarly, the density of gasoline is less than the density of oil (710 kg/m3 < 900 kg/m3), which means that oil is denser than gasoline. This implies that oil will sink below gasoline.

Based on these comparisons, we can conclude that the oil will be in the intermediate level in the third container. It will float on top of water and sink below gasoline.

Therefore, the answer to the second question is:

A) Bottom level
