Energy is the ability to do work. Energy can change from one energy to another

Potential energy is the energy that an object has because of its position

The potential energy can be formulated:

Ep = m. g. h

E = potential energy of an object, joule

m = object mass, kg

g = gravity acceleration, m / s²

h = height of an object, m

energy of coal = 3.10⁶ J

mass = 1 kg

g = 9.8 m/s²

[tex]\tt h=\dfrac{E}{m.g}\\\\h=\dfrac{3.10^6}{1\times 9.8}=3.06\times 10^5`m[/tex]

Answer:

3px

Explanation:

The electronic configuration of sulphur is given as;

1s2 2s2 2p6 3s2 3px2 3py1 3pz1.

Recall that in accordance with Hund's rule, electrons occur singly first before pairing takes place during the filling of degenerate orbitals.

The last sub-level into which electrons are filled in sulphur is the 3p sub-level having three degenerate orbitals, 3px, 3py and 3pz.

According to Hund's rule, these levels are first singly filled before pairing begins. Hence the last electron in sulphur goes into the 3px orbital.

Answer:

Gravity exists because elementary particles (electrons, quarks, and neutrinos), are NOT static with time and expansion. Matter is dynamic; elementary particles must continually accrete energy (the quanta of space) in order to conserve the continually increasing angular momentum of the expanding universe.

Answer:

Sodium has a mass number of 23amu. Since sodium has 11 protons, the number of neutrons must be 23 – 11 = 12 neutrons.

Explanation:

The mass number is given at the top left of the elements symbol, for example, sodium has a mass number of 23.

Sodium (Na) square from the periodic table. The mass number (23) is top-left. The atomic number (11) is bottom-left.

We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons.

The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass).

Sodium has a mass number of 23amu. Since sodium has 11 protons, the number of neutrons must be 23 – 11 = 12 neutrons.

Answer: Chemical bond. Two atoms in the same molecule are linked together by a chemical bond. Write "bond" in the blank.

Two atoms in the same molecule are linked together by a chemical bond.

A chemical bond is defined as the formation of a chemical compound by the union of  two or multiple atoms, ions, or molecules, the firmness can be evaluated by the type of its chemical bond.

Ionic Bond is a type of chemical bond where relocation of electrons from one atom to alternative atom,  one atom creates a negative charge called as anion while another atom creates a positive charge called cation.

The covalent bond defines the distribution of electrons among atoms, it can be either polar or non polar in nature and the electrons are united unevenly in polar covalent chemical bonding.

Hydrogen Bonding is  a fragile procedure of chemical bonding, this type of polar covalent bonding occur between oxygen and hydrogen where  hydrogen develops a partial positive charge in the formation of the water.

the answer is air

Explanation:

Answer:

B. From the air

Explanation:

Answer:

If an ion has a positive charge then it has lost an electrons.

Explanation:

So you don't "gain" anything when the ion has a positive charge. It loses an electron which means it has more protons than electrons. Thus, the ion has a positive charge. If it "gained" an electron then it would have a negative charge.

Answer:

E = 12.92 × 10^(-16) J

Explanation:

Formula for energy is;

E = hc/λ

Where;

h is Planck's constant = 6.63 x 10^(-34) J.s

c is speed of light = 3 × 10^(8) m/s

λ is wavelength = 0.154 nm = 0.154 × 10^(-9) m

E = (6.63 x 10^(-34) × 3 × 10^(8))/(0.154 × 10^(-9))

E = 12.92 × 10^(-16) J

The energy associated with the photons of X rays with a wavelength of 0.154 nm is 1.29 × 10⁻¹⁵ J.

When copper is bombarded with high-energy electrons, X rays, with a wavelength of 0.154 nm (λ) are emitted.

We can calculate the energy (E) associated with the photons of these X rays using the Planck-Einstein relation.

[tex]E = \frac{h \times c }{\lambda } = \frac{(6.63 \times 10^{-34}J.s ) \times (3.00 \times 10^{8}m/s ) }{0.154 \times 10^{-9} m } ]= 1.29 \times 10^{-15} J[/tex]

where,

The energy associated with the photons of X rays with a wavelength of 0.154 nm is 1.29 × 10⁻¹⁵ J.

Answer:

Wing length

Explanation:

According to the given excerpt, independent variable is 'wing length' and dependent variable is 'amount of time it takes for helicopter to hit the floor'.

Independent variable refers to the variable that do not undergo any change or shift in the course of the experiment of research. The other variables are measured using the constant independent variable. The value obtained from the independent variable is independent. On the other and, the dependent variable witnesses change with respect to the independent variable.

A solute gets dissolved in something else. (solvent)

A solute is a substance which dissolves in something else, like a solution. As a result, a homogeneous mixture is formed. A solute can be a gas, solid or a liquid.

A solvent is a substance in which a solute happens to dissolve in order to  produce a homogenous mixture. Solvents can also exist as solids, liquids as well as gases.
For example, NaCl is a solute which dissolves in water, which is a solvent. The equation is as follows
NaCl (aq) + H2O (l) → NaOH (aq) + HCl (aq)
Hence, option A is the correct option.
