Answer:

Sugar will dissolve, so water.

Explanation:

Sugar is a bicubacle food source you could say, sand will not evaporate or dissolve in the water since it is not a 3c2e source. Using water will seperate them.

Answer: Heat

Explanation:

Because is you put water and sand in a container you can separated by boiling the water and all the water would evaporate and the sand would stay.

Answer:

White whale

Explanation:

Just because I never seen a white whale:)

The specific heat  capacity of the metal : 0.610 J/g° C  

The law of conservation of energy can be applied to heat changes, i.e. the heat received/absorbed is the same as the heat released  

Q abs = Q received  

Heat can be calculated using the formula:  

Q = mc∆T  

Q = heat, J  

m = mass, g  

c = specific heat, joules / g ° C  

∆T = temperature difference, ° C / K  

∆T = T(final temp) - T(initial temp)

mass of metal = 38 g

T initial metal = 92 °C

mass of water = 43 g

T final water = 30  °C

T initial water = 22°C

c water = 4.18 J/g° C  

[tex]\tt Q=m.c.\Delta T\\\\Q=43\times 4.18\times (30-22^oC)\\\\Q=1437.92~J[/tex]

Q water = Q metal

[tex]\tt 1437.92=38\times c\times (92-30)\\\\c=0.610~J/g^oC[/tex]

Explanation:

becuase of sound waves

Answer:

4.00 g/mL

Explanation:

Density is mass divided by volume (g/mL).

Mass of rock = 21.58

Volume of rock = 25.4 - 20.0 = 5.4mL

Density of rock = 21.58g / 5.4mL = 3.99629 g/mL

Round to the lowest number of significant figures which is three = 4.00 g/mL

Explanation:

Each orbital within a particular sublevel is distinguished by its value of ml. This quantum number may be more aptly named the orbital orientation quantum number. In each energy sublevel (designated by l) there are 2l+1 possible independent orientations of the electron cloud.

Answer:

[tex]m_l-magnetic[/tex]

Explanation:

The principal energy level, n, tells us which shell it is in and the total energy of the electron.

The angular momentum (azimuthal), l, tells us which sublevel/subshells the electron is in.

The magnetic, m sub l, tells us the orientation the electron is spinning.

Answer:

Avoid plagiarism and the work of others

Explanation:

I took the test and got it right. Hope this helps :)

Avoiding plagiarism of the work of others shows that you have intellectual honesty. So the correct option is B.

The act of presenting someone else's ideas or work as your own, with or without that person's agreement, by integrating it into your work without giving it due credit, is known as plagiarism. This definition applies to all works, both published and unpublished, whether they are in manuscript, print, or electronic form.

Plagiarism can be willful, careless, or accidental. Plagiarism that is deliberate or careless is prohibited under exam regulations and is grounds for disciplinary action. In addition to text, additional media such as computer code, pictures, graphs, etc. must also include credit for the ideas and works of others.

It equally applies to both published and unpublished text and data taken from books and journals, lectures, theses, and other students' writings. Text, information, or other materials that you take from websites must also be credited.

Learning and using the rules of good academic practice from the start of your university career is the best way to prevent plagiarism.

Therefore the correct option is B.

Explanation

Answer:

This story that is related to the movement of water in relation to the amount of solute seeks to explain the process of OSMOSIS in a very interesting way.

Explanation:

The OSMOSIS process is a process where water diffuses from a compartment with fewer solutes to one with higher solutes, that is why the osmotic intention is to balance the concentrations and molarities between both compartments, this is called osmotic balance.

For this to happen, a highly water-permeable barrier is needed.

Answer:

The density of wood is 32 g/cm³.

Explanation:

Given data:

Mass of wood = 768 g

Volume of wood = 24 cm³

Density of wood = ?

Solution:

Density is equal to the mass divided by its volume.

Formula:

d = m/v

d = density

m = mass

v = volume

d = 768 g/ 24 cm³

d = 32 g/cm³

The density of wood is  32 g/cm³.

Answer:

3.16×10⁹ pL

Explanation:

Given data:

Volume in mL = 3.16

Volume in picoliters = ?

Solution:

Picoliter and milliliters are units of volume. Milliliter is greater unit than picoliter.

1 mL = 10⁹ pL

Now we will convert the 3.16 mL into pL.

3.16 mL × 10⁹ pL/ 1 mL

3.16×10⁹ pL

Answer:

Option B. Sink to the bottom of the container.

Explanation:

From the question given above, the following data were obtained:

Density of ice = 0.92 g/cm³

Density of rubbing alcohol = 0.80 g/cm³

From the density of both substance given, we can see clearly that the ice has a higher density when compared with the rubbing alcohol.

Thus, If an ice cube is placed in a container of rubbing alcohol, the ice cube will not float rather, it will sink to the bottom of the container because the ice has a higher density than the rubbing alcohol.

Answer:

t = 27 s

Explanation:

Given data:

Average acceleration = -0.50 m/s²

Time taken to reach to the 13.5 m/s = ?

Solution:

Formula:

Vf = V₀ + at

Vf = 0

V₀ = 13.5 m/s

a = -0.50 m/s²

Now we will put the values in formula.

0 = 13.5 m/s - 0.50 m/s²t

0.50 m/s²t =  13.5 m/s

t =  13.5 m/s / 0.50 m/s²

t = 27 s
