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.

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question

N = 7.14 × 10^35 molecules of O2

We have

[tex]n = \frac{7.14 \times {10}^{35} }{6.02 \times {10}^{23} } \\ [/tex]

We have the final answer as

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.

According to the law of conservation properties of Matter in a closed system the mass of reactants is equal to the mass of products. Because there is no lose of matter or energy in closed system

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:

It has shells of protons and neutrons.

Explanation:

The nuclear structure of an atom is similar to the non-nuclear structure because has shells of protons and neutrons.

An atom consists of a central nucleus that is usually surrounded by one or more electrons.

The total number of neutrons plus protons in the same both before and after the nuclear process, although the total number of protons and the total number of neutrons may be different before and after.

Hence, the nuclear structure of an atom is similar to the non-nuclear structure because has shells of protons and neutrons.

Answer:

Heat required to melt 42 g if ice is 13,860 J

Explanation:

The amount of heat required to melt  grams of water at 0°C is given as follows;

The mass of the ice (water), m = 42 g

The latent heat of fusion of ice Δ[tex]H_f[/tex]= 330 J/g

Therefore, heat required to melt 42 grams is given as follows;

Heat required to melt ice = Mass of the ice, m × The specific latent heat of fusion of the ice, Δ[tex]H_f[/tex]

Heat required to melt 42 g if ice = m × Δ[tex]H_f[/tex] = 42 g × 330 J/g = 13,860 J

Heat required to melt 42 g if ice = 13,860 J.

Answer:

a) 6.17 g of solid KOH

b) 88.0 mL of a 1.25 M potassium hydroxide solution​

Explanation:

a) We have to determine the mass of solid potassium hydroxide that has to be weighed to prepare 220 mL of a 0.500 M potassium hydroxide solution. We will also require the molar mass of potassium hydroxide, KOH, 56.11 g/mol.

0.220 L × (0.500 mol/L) × (56.11 g/mol) = 6.17 g

b) We will use the dilution rule to determine the volume of the 1.25 M potassium hydroxide solution​ to be measured.

C₁ × V₁ = C₂ × V₂

V₁ = C₂ × V₂ / C₁

V₁ = 0.500 M × 220 mL / 1.25 M = 88.0 mL

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]
