A process by which softer, less weather-resistant rocks wear away and leave harder, more weather-resistant rocks behind is called a. differential weathering. c. chemical weathering. b. mechanical weathering. d. ice wedging.

Answer:

E = 19.89×10⁻¹⁶ J

λ = 1×10⁻¹ nm

Explanation:

Given data:

Frequency of xray = 3×10¹⁸ Hz

Wavelength of xray = ?

Energy of xray = ?

Solution:

speed of wave = wavelength × frequency

speed = 3×10⁸ m/s

3×10⁸ m/s  = λ ×3×10¹⁸ s⁻¹

λ = 3×10⁸ m/s  / 3×10¹⁸ s⁻¹

λ = 1×10⁻¹⁰m

m to nm:

λ = 1×10⁻¹⁰m×10⁹

λ = 1×10⁻¹ nm

Energy of x-ray:

E = h.f

h = plancks constant = 6.63×10⁻³⁴ Js

by putting values,

E = 6.63×10⁻³⁴ Js ×3×10¹⁸ s⁻ ¹

E = 19.89×10⁻¹⁶ J

Answer:

The answer is a) [tex]C_{4} H_{16} O_{5}[/tex]

Explanation:

The other chemical formulas' subscripts share a common factor, so they can be simplified to an empirical formula, however, the subscripts in  [tex]C_{4} H_{16} O_{5}[/tex] cannot be simplified any further, because they do not share any more whole-number factors with each other.

Answer:

Error or mistakes during DNA replication is accountable for two-thirds or 66% of the cancer cases. These random and unpredictable errors called mutations that occur during the division of a cell as an error in copying of DNA.

DNA replication has three main steps:

Opening and separation of DNA strands of a helix - carried by an enzyme known as helicase that breaks the hydrogen bonds between nitrogenous bases of the helix of DNA.

The priming of the template strand - DNA primase helps RNA primers to bind to both strands at 3' end as soon as it separated

strat assembling the segments of new DNA on strands called elongation of the strands with help DNA polymerase I and after forming new strands the termination of the replication.

Errors or mistakes can occasionally take place if DNA polymerase inserts a wrong base during elongation of the strands.

Answer:

See the answer below

Explanation:

1. Organisms produce energy for cells by chemically breaking down and unlocking the energy locked-up within food materials in a process known as cellular respiration. The unlocked energy is then utilized for the cell's metabolic activities.

2. Cellular respiration can be aerobic or anaerobic.

Aerobic respiration involves the breakdown of carbohydrates in the presence of oxygen to yield energy in the form of ATP while carbon dioxide and water are produced as by-products.

        [tex]C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP[/tex]

Anaerobic respiration involves the breakdown of carbohydrates in the absence of oxygen to produce ATP and lactic acid as a by-product. The lactic acid is later oxidized to carbon dioxide and water to prevent it from building up.

       [tex]C_6H_1_2O_6 -> 2C_3H_6O_3 + ATP[/tex]

3. Photosynthesis and cellular respiration are both considered metabolic processes that take place in living organisms. However, photosynthesis is peculiar only to green plants and some algae while respiration is common to all living organisms. While photosynthesis is anabolic, that is, it involves the building up of materials; respiration is said to be catabolic because it involves the breaking down of materials.

During photosynthesis, inorganic products are utilized to produce carbohydrates for plants with oxygen gas released as a by-product according to the following equation:

       [tex]6CO_2 + 6H_2O --> C_6H_1_2O_6 + 6O_2[/tex]

During respiration, the food taken by living organisms is broken down to unlock the energy in it for metabolic activities according to the following equation:

     [tex]C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP[/tex]

Answer:

It gains electrons.

Explanation:

Got it right on a quiz.

When electrons are added to or taken away from an object, an electrical charge is produced. An object acquires a negative charge when electrons are introduced to it because electrons have a negative charge. An object acquires a positive charge when its electrons are removed.

When a thing picks up electrons, it becomes negatively charged. Non-metals gain electrons at the atomic level to fill their outer electron orbitals. An atom that is negatively charged and has more electrons than protons is said to be an anion.

Some atoms have the ability to draw in more electrons, making them negatively charged. Ions are defined as atoms that are not electrically neutral.

This is Newtons 2nd Law: Force is directly proportional to the acceleration of the object, acceleration is inversely proportional to the mass of the object.

Answer: I believe that it is that the forces are balanced.

Explanation:

Answer:

false

Explanation:

Because in a periodic table they are not located below each other and therefore do not have the same number of electrons.

Answer:

Explanation:

Speed of light = Wavelength x Frequency.

605 nm x Frequency = 3x10^8 m/s

6.05 x 10^-7 m x Frequency = 3x10^8 m/s

Frequency = 4.96 x 10^14 Hz

Answer:

ν=4.96x10^14 Hz

Explanation:

c=λν

λ=wavelength

ν=frequency

in this problem:

c=3x10^8

λ=605x10^-9

so ν=c/λ

v=(3x10^8)/(605x10^-9)

v=4.96x10^14

The term known as "Nuclear Fusion" is a very important concept in chemistry and it is studied mostly under the topic or aspect of Chemistry known as or called radioactivity. Nuclear Fusion is the kind of reaction in which two or more atomic nucleus combines to for bigger ones.

There is a saying that there is no life without nuclear fusion because it is the reaction that causes the stars to have light.

Option 'd' is correct. This is what happens in stars in order for light to be produced that is the inward movement of gravity and the outward movement of nuclear fusion.

trigonal pyramidal

Explanation:

In NF3, the nitrogen atom is sp3 hybridized. Now we must remember that according to the VSEPR theory, the number of electron pairs in the valence shell of the central atom in a molecule determines its shape.

Here, the nitrogen atom is the central atom and its outermost shell is surrounded by four electron pairs - one lone pair and three bond pairs. This means that it has a tetrahedral electron pair geometry.

However, due to the lone pair, the three fluorine atoms are arranged in a  trigonal pyramidal geometry. Hence the correct shape of the molecule is trigonal pyramidal.

Answer:

54.5%

Explanation:

The percentage composition of oxygen in C₆H₈O₆ can be obtained as follow:

Molar mass of C₆H₈O₆ = (12×6) + (8×1) + (16×6)

= 72 + 8 + 96

= 176 g/mol

Next, there are 6 oxygen atoms in C₆H₈O₆. Therefore the mass of oxygen in C₆H₈O₆ is:

Mass of Oxygen = 16 × 6 = 96 g

Finally, we shall determine the percentage composition of oxygen in C₆H₈O₆ as follow:

Percentage of oxygen =

Mass of Oxygen/mass of C₆H₈O₆ × 100

Percentage of oxygen = 96 / 176 × 100

Percentage of oxygen = 54.5%

Thus, the percentage composition of oxygen in C₆H₈O₆ is 54.5%.
