Answer:

A

Explanation:

When you crumble a piece of paper it make a sound plus i just did on apex

When we crumple a piece of paper in our hands, a part of the energy is transformed into sound energy. Therefore, option (A) is correct.

Sound transmits through the medium such as liquids, gases, and plasma in the form of longitudinal waves or compression waves. It requires a medium to propagate as it can travel through solids as both longitudinal and transverse waves.

Transverse sound waves exhibit waves of alternating shear stress perpendicular to the direction of propagation while Longitudinal sound waves exhibit alternating pressure deviations leading to compression and rarefaction.

Generally, waves move matter up and down but do not carry along.  When we crumple the paper with our hands the kinetic energy of our hands is used to deform the paper but at the same time, we can listen to some sound which indicates that some energy is transformed into sound energy.

Answer:

warm, dry downslope wind affecting Southern California - Santa Ana wind

a seasonally changing wind- monsoon

wind blowing from a valley up a mountain slope - valley breeze

generated by cold thunderstorm downdrafts - haboob

Explanation:

The Santa Ana wind occurs in early autumn. They bring hot and dry weather to areas around the South-West coast. They move at high speeds, affecting most parts of Southern California.

Monsoon is a seasonal wind that blows across Southern Asia. It usually blows in summer. It is a a seasonally changing wind.

Valley breeze is an example of convection current in nature. It is produced by rapid warming of the valley floor leading to the expansion of air making it to flow up the slopes. At night, radiation from the surface cools the slopes. This leads to the rise of cooler and denser air which drains into the valley.

Haboob is generated by cold thunderstorm downdrafts. It is associated with large sandstorms and dust storms.

Answer:

The alkali metals consist of the chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr).

Explanation:

They are called alkali metals because they are in the alkali group.

Explanation:

Glucose (C₆H₁₂O₆) is an electrolytes hence it conduct electricity.

Therefore,

Option B is correct.

Answer: zero

Explanation:

its zero because when something is neutral is not on either team because with numbers there is positive numbers and negative numbers but zero isn't positive or negative so its neutral. ps: can I get branliest

Answer:

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

From the question

volume = 325 mL

density = 0.874 g/mL

We have

mass = 325 × 0.874

We have the final answer as

Answer:

53.11× 10²³ molecules

Explanation:

Given data:

Number of molecules of CO₂ = ?

Mass of CO₂ = 388.1 g

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass of CO₂ = 12× 1 + 16×2

Molar mass of CO₂ = 44 g/mol

Now we will put the values in formula.

Number of moles = 388.1 g/ 44 g/mol

Number of moles = 8.82 moles

Now we will calculate the number of molecules by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ molecules

8.82 mol × 6.022 × 10²³ molecules / 1 mol

53.11× 10²³ molecules

Brainliest plz?

Answer:

Now times by Abogadros constant: 1* 6.022*10^23=6.022*10^23 molecules of CO2 are present.

Explanation:

We know the molar mass of CO2(g) is 44.01⋅g⋅mol−1 . And so Avogadro's number of carbon dioxide molecules have this mass... And we take the product of the quotient... Molecules of carbon dioxide=5.00⋅mol×6.022×1023⋅mol−1≅30×1023⋅carbon dioxide molecules.

Answer:

Mass is both a property of a physical body and a measure of its resistance to acceleration when a net force is applied.

[tex]\boxed {\tt D. \ Hydrogen}[/tex]

Explanation:

An element has a uniform composition, cannot be broken down by chemical change, every atom has the same atomic number, and can be found on the Periodic Table.

Water is made of hydrogen and oxygen atoms (H₂O) so it is not an element.

Table salt is made of sodium and chloride atoms (NaCl) so it is not an element.

Iron oxide is made up of iron and oxygen atoms, so it is not an element.

Hydrogen is an element. It can be found on the Periodic Table as element H.

The correct answer is D. Hydrogen

Earthquakes: Nature's most unpredictable and one of her most devastating natural disasters.

Answer:

Earthquake

Explanation:

Because we have not discovered any high techto predict it, In 2011 a 9.0 earthquake hit the coast of Sendai they had no warning

Answer:

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass = 16,000 g

volume = 800 cm³

We have

[tex]density = \frac{16000}{800} = \frac{160}{8} \\ [/tex]

We have the final answer as

Answer:

0.2007 nm

3.57 cm

0.01478 g

8280000 pg

Explanation:

1)200.7 pm

1 picometer is equal to 0.001 nanometer.

1 nm = 1000 pm

200.7 pm× 1 nm / 1000 pm  = 0.2007 nm

2)0.000357 hm

1 hectometer is equal to 10,000 centimeter.

1 hc = 10,000 cm

0.000357 hc× 10,000 cm / 1 hc = 3.57 cm

3) 14.78 mg

1 gram is equal to 1000 milligram.

1 g = 1000 mg

14.78 mg × 1 g/1000 mg = 0.01478 g

4)8.280 µg

1 microgram is equal to 10⁶ picogram.

1 µg = 1000000 pg

8.280 µg× 10⁶ pg/ 1µg = 8.280×10⁶ pg or 8280000 pg
