A student drops a ball from 5 feet above the ground. After bouncing once, it only reaches a maximum height of 4 feet above the ground. Use energy terms to explain why the ball did not reach its original height after bouncing once.

Answers

Answer 1

Answer:

because the gravity of the ball can't go that high

Answer 2

There is a law called conservation of energy which states that energy can neither be created nor be destroyed. It can be only transferred from one form to another form. Therefore, some energy is lost  to the environment as sound or heat.

What is energy transfer?

Energy transfer is a phenomenon in which energy transfer from one matter to another matter. Energy can be transferred in two forms that are by doing work or by transferring heat.

Heat can be transferred by three ways conduction, convention and radiation. In conduction, when two object are in direct contact, transfer of molecules takes place. As the ball impacted the ground, the energy would have been lost to the environment as sound or heat.

Therefore, some energy is lost  to the environment as sound or heat.

why is the symbol [Ar] used in the electron configuration of potassium, and what does it represent?

Answers

Answer:

To denote a stable inner configuration and it represents argon

Explanation:

The symbol [Ar] used in the electron configuration of potassium represents the inner electronic configuration of the element.

This argon atom is stable octet with completely filled shells. Most noble gases are used to write the electronic configuration of other atoms. The inner atomic orbitals of elements are similar to those of nearby noble gases.

Ar is Argon with a configuration of 1s² 2s² 2p⁶ 3s² 3p⁶So, this configuration is stable and it the inner configuration of potassium excluding the outermost orbitals.

CaO + H2O -> Ca(OH)2
3.50g of Ca(OH)2 was made from 4.20g of CaO? What is the % yield of Ca(OH)2?

Answers

The % yield of Ca(OH)₂ : 62.98%

Further eplanation

Percent yield is the compare of the amount of product obtained from a reaction with the amount you calculated

General formula:

Percent yield = (Actual yield / theoretical yield )x 100%

An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients

Reaction

CaO + H₂O ⇒ Ca(OH)₂

mass CaO= 4.2 g

mol CaO(MW=56,0774 g/mol) :

[tex]\tt mol=\dfrac{mass}{MW}\\\\mol=\dfrac{4.2}{56,0774 g/mol}\\\\mol=0.075[/tex]

mol Ca(OH)₂ based on mol CaO

mol ratio CaO : Ca(OH)₂,= 1 : 1, so mol Ca(OH)₂ = 0.075

mass Ca(OH)₂(MW=74,093 g/mol) ⇒ theoretical

[tex]\tt mass=mol\times MW\\\\mass=0.075\times 74,093 g/mol\\\\mass=5.557~g[/tex]

% yield :

how many atoms are there in 1g of argon the Avogadro constant is 6.02 x 10^23 per mole relative atomic mass (Ar): AR=40

Answers

Answer:

ow many atoms are there in 1g of argon the Avogadro constant is 6.02 x 10^23 per mole relative atomic mass (Ar): AR=40Explanation:

The number of atoms of argon in 1g of argon is 1.5 × 10²² atoms

From the question,

We are to determine the number of atoms present in 1g of argon.

To determine this,

First we will calculate the number of moles of the 1g of argon

From the formula

[tex]Number\ of\ moles = \frac{Mass}{Atomic\ mass}[/tex]

From the given information

Mass of Argon = 1g

Atomic mass of Argon = 40g/mol

∴ Number of moles of Argon = [tex]\frac{1}{40}[/tex]

Number of mole of Argon = 0.025 mole

Now,

For the number of atoms of argon present

Using the formula

Number of atoms = Number of moles × Avogadro's constant

∴ Number of atoms of argon present = 0.025 × 6.022×10²³

Number of atoms of argon present = 1.5055 × 10²² atoms

Number of atoms of argon present ≅ 1.5 × 10²² atoms

Hence, the number of atoms of argon in 1g of argon is 1.5 × 10²² atoms

help me find out how to get the volume !!! pleaseeee

Answers

The volume using the cylinder formula  : V=πr²h

Further explanation

Charles's Law  

When the gas pressure is kept constant, the gas volume is proportional to the temperature  

[tex]\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}[/tex]

This experiment is an illustration of Charles's law, to determine the relationship between temperature and gas volume

If a certain amount of gas is heated, the volume will increase

So in this experiment, the temperature was changed as an independent variable and tube volume as a fixed variable

Because the tube is cylindrical, to find the volume using the cylinder formula

[tex]\tt V=\pi.r^2.h[/tex]

Meanwhile, to find the radius, you can use a caliper to measure the diameter of the tube and the result will be divided by 2

There was a large population of woodpeckers living in a forest. Some of the woodpeckers had long beaks, some of the woodpeckers had short beaks. During a very rainy year, the bark on most of the trees grew very thick. Only the woodpeckers with the longest, strongest beaks could drill deep enough into the thick bark to find the insects they depend upon for food. Woodpeckers with short beaks could not drill in deep enough to reach the insects. If the rainy weather continues for several years, what do you expect would happen to the woodpecker population because of natural selection?

Which statement describes the water gas particles in the air above the cup compared with the water liquid
particles in the cup?
The partides move faster and are closer together
The particles move faster and are far apart
The particles move slower and are closer together
The particles move slower and are far apart

Answers

Answer:

The particles move faster and are far apart

Explanation:

A substance may exist in three states of matter; solid, liquid and gas.

In the solid state, there is very strong intermolecular forces between the particles of the substance. They can only vibrate or rotate about their mean positions but can not translate.

In the liquid state, the particles of the substance have a greater degree of freedom than in the solid. The magnitude of intermolecular forces is lower than in solids, the molecules can move at low speeds.

In a gas, the molecules are separated from each other with negligible intermolecular interaction hence they move at very high speed.

Therefore, for the water gas particles in the air above the cup; the particles move faster and are far apart.

10. The wavelength of the color red is 650 × 10⁻⁹ m

11. The frequency of the color red is approximately 4.6122 × 10¹⁴ Hertz

12. The corresponding energy  is approximately 3.058 × 10⁻¹⁹ J

Explanation:

10. Given that the wavelength, λ, of the color red is 650 nm, and one nanometer, nm = 10⁻⁹ m, we have;

The wavelength of the color red = 650 × 10⁻⁹ m

11. The frequency, v, of the color red is obtained from the relation, v = c/λ

Where;

c = The speed of light = 299,792,458 m/s

∴ v = 299,792,458/(650 × 10⁻⁹) ≈ 4.6122 × 10¹⁴ Hertz

12. Given that energy emitted by light, E = h × v, where E = 6.63 × 10⁻³⁴ J/s, we have;

E = 6.63 × 10⁻³⁴ J·s × 4.6122 × 10¹⁴ Hz ≈ 3.058 × 10⁻¹⁹ J

Therefore,  the corresponding energy, E ≈ 3.058 × 10⁻¹⁹ J.
