Answer:
Rydberg constant 3.3 x 10¹⁵ Hertz is equal to 1.090 x 10⁷ m⁻¹
Explanation:
Given;
Rydberg constant as 3.3 x 10¹⁵ Hz
1 Rydberg constant = 3.3 x 10¹⁵ Hz
1 Rydberg constant = 1.090 x 10⁷ m⁻¹
Therefore, Rydberg constant 3.3 x 10¹⁵ Hertz is equal to 1.090 x 10⁷ m⁻¹
Here, we are required to identify another value for the Rydberg constant part from 3.3 × 10¹⁵Hz.
This value is also R = 1.1 × 10⁷.
The Rydberg constant, R is a constant relating to the electromagnetic spectra of an atom.
The value of Rydberg constant is 3.3 x 10¹⁵Hz above and is in terms of the Frequency of the spectra lines.
However, another way to express Rydberg constant is by dividing its value above by the speed of light, c to yield;
R = R'/c where c = speed of light = 3 × 10⁸m/s.This Rydberg value is also, R = (3.3 × 10¹⁵)/3×10⁸.
Therefore, this value is also R = 1.1 × 10⁷.

Most elements' names end in the suffix -ium. This practice started around the year 1800, with many elements discovered before that having a more common name. However, some elements are more recently discovered and don't end in -ium. Do you notice any patterns for these elements?
Answer:
The last naturally occurring element to be discovered was francium (87) in 1939. Since that discovery, plutonium (94), neptunium (93) and astatine (85), which were initially created in the lab in 1940, have since been found in nature.
Explanation:
The -ium suffix is just a Latin suffix that creates abstract nouns, therefore, it's being used to construct scientific component names from their nomenclature origin, including such minerals (calcium from calx) or person names (gadolinium), and further discussion can be defined as follows:
This denotes a metallic element including platinum or barium. It's a group that forms positively charged ions: ammonia chloride, hydronium ion. It indicates a cellular structure, syncytium Etymology, New Latin, via Latin, via Greek -ion, small suffix.Its last found natural element found is francium (87) in 1939. Ever since, plutonium (94), neptunium (93), and astatine (85), which were synthesized inside the lab in 1940, have indeed been discovered throughout nature.Learn more:

When you get home, you smell cookies baking. You respond by walking toward the kitchen. Many signals move through your
nervous system in this process. Which component is involved first? (1 point)
O axons in your motor neurons
axons in your sensory neurons
Odendrites in your motor neurons
O dendrites in your sensory neurons
Answer:
dendrites in your sensory neurons
Explanation:
Sensory neurons are first activated, then the stimulus is transmitted horizontally between them, spreading perception through the olfactory bulb that captures the smell of a baked cookie.
After this, the axons are activated to transmit to the motor neurons that will carry out the action of walking towards the kitchen.
Describe two ways the material in this lesson illustrates the importance of creativity in scientific investigation
Answer:
Dalton used creativity to modify Proust's experiment and interpret the results. Millikan used creativity to develop a way to measure the charge on an electron. Thomson used creativity to interpret the results of the cathode ray tube experiment.
Explanation:
Creativity enables scientists to devise new ways of solving old problems.
I do not know what your material contains, however, creativity is key in scientific investigation. The term "science" is coined from the Latin word "scientia" which means knowledge.
In science, we endeavor to create new knowledge through research and innovation. This requires that a scientist must think of new and efficient ways of solving old problems. This underscores the centrality of creativity in scientific investigation.

Answer:
The distance between the beginning of the first P wave and the first S wave tells you how many seconds the waves are apart.
Explanation:
This number will be used to tell you how far your seismograph (an instrument that measures and records details of earthquakes, such as force and duration) is from the epicenter (the point on the earth's surface vertically above the focus of an earthquake) of the earthquake. Measure the distance between the first P wave and the first S wave.

Temperature in °C
Independent Variable
Dependent Variable
pls helppp asap
Answer:
Temperature - Independent variable
The solubility of CO2 and Solubility of O2 - Dependent variable
Explanation:
There are always two variables in an experiment: Independent and dependent variables.
Independent variables are defined as the variables that can be controlled or changed to measure its effect on the dependent variable and the dependent variable is influenced by the change in Independent variables.
In the given example, the temperature is the Independent variable and the solubility of CO2 and Solubility of O2 is the dependent variable because the solubility of CO2 and O2 decreases as temperature increases.
Hence, the correct answer is:
Temperature - Independent variable
The solubility of CO2 and Solubility of O2 - Dependent variable

why does the reactivity of elements increase going down Group 1 from lithium to rubidium but decreases going down Group 7 from fluorine to iodine?
Answer: The reactivity of group 7 elements decreases down the group because, as you go down the group: The atoms get larger. The outer shell gets further from the nucleus. The attraction between the nucleus and electrons gets weaker, so an electron is less easily gained.

What are the two laws of conservation of energy?
Answer:
Explanation:
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside. This is particularly confusing in the case of non-conservative forces, where energy is converted from mechanical energy into thermal energy, but the overall energy does remain the same. The only way to use energy is to transform energy from one form to another.
Answer:
The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law of thermodynamics states that the entropy of any isolated system always increases.

Answer:
1. chemical 2. potential
Explanation:
energy, potential energy, is stored in the covalent bonds holding atoms together in the form of molecules. This is often called chemical energy.Energy is found in different forms, but all energy falls into the following two categories – potential energy and kinetic energy. Potential energy is stored energy, or the energy of position. It consists of the following forms: Chemical energy is energy stored in the bonds between atoms in molecules.
The form of energy stored in the bonds between atoms is chemical energy. This form of energy falls into the potential energy category.
What is chemical energy ?The term chemical energy is defined as the energy of chemical substances that is released when they are undergo the process of chemical reaction and covert into the another substances.
The chemical energy is used to create heat and electricity along the world. Some peoples also burn these fuels on more minor scales to formed heat to keep buildings warm. They burn fossil fuels like natural gas, oil, and petroleum to produce steam to turn turbines that formed heat and electricity.
The energy stored in chemical bonds is called as chemical energy therefore, it is a form of potential energy. The examples of potential energy are the energy of water present behind a dam.
Thus, The form of energy stored in the bonds between atoms is chemical energy. This form of energy falls into the potential energy category.
