Answer: Option (B) is the correct answer.

Explanation:

When a liquid changes into vapors or gas then this process of change is known as evaporation.

A mixture in which solute particles completely dissolve in even composition throughout the solvent then it is known as homogeneous mixture.

For example, when salt is dissolved in water then upon heating it water can be evaporated and crystals of sodium chloride can be obtained.

Whereas screening method is used in the discovery of a drug and it a scientific experimentation method.

When particles of a mixture are separated by spinning then this process is known as centrifugation.

When a magnetic force is used to separate magnetic particles present in a mixture then this process is known as magnetic separation.

Thus, we can conclude that evaporation is the separation method would be most successful in separating the components of a homogeneous mixture.

The smith family uses more energy in the summer than the winter what is a good explanation for this?
DENIUS [597]
They use fans and air conditioning in the summer because its hot, which means they use energy and in the winter, there is no need because its cold so less energy.

dimaraw [331]

Answer : The correct statement is:

The density of each piece is the same as that of the original block.

Explanation :

Intensive property : It is defined as a property of substance which does not change as the amount of substance changes.

Examples: Temperature, refractive index, density, hardness, etc.

According to question, if Ana has a block made of pure gold and she cuts this block into two equal pieces then the density of each piece is the same as that of the original block because density is an intensive property that does not changes until and unless material is changed.

That means density remains same as that of the original piece.

Hence, the correct statement is the density of each piece is the same as that of the original block.

Two hydraulic cylinders are connected. If the diameter of one piston is twice the other, the how does the pressure experienced b
Aneli [31]

Answer:

They experience the same pressure

Explanation:

To answer this question, we recall Pascal's, Law Pascal's law states that  an increase in pressure at a point in a confined cylinder containing a fluid, there is also an equal increase at all other points in that cylinder.

According to Pascal's law the pressure if the pressure expereienced by the larger diameter piston increases, the pressure experienced by the smaller diameter piston also increases by the same amount

However considering that pressure = Force/area F1/A1 =F2/A2

thus where A1 = πD²÷4 and A2 = πD²÷ 16 we have

we have F1×4/πD² = F2×16/πD² or F1 = 4× F2

They experience the same pressure but the larger cylinder delivers four times the force transmitted from he outside to the smaller cylinder
