1. <em>Describe</em>
Frequency (f) and wavelength (λ) are inversely related.
f ∝ 1/λ
As one goes up, the other goes down and vice versa.
2. <em>Infer
</em>
The frequency of infrared light is less than that of red light, so infra could mean something like less than or below or beneath.
Ultrahigh frequencies are extremely high compared with those of visible light. Ultrasound has frequencies that are far beyond what we can hear. An ultracentrifuge goes at extremely high speed, and an ultramicroscope can “see” tiny structures. Ultra could probably mean something like extremely or far beyond.
3. <em>Analyze
</em>
Energy is directly proportional to frequency (E ∝ f).
Frequency is inversely proportional to wavelength (f ∝ 1/λ).
Energy is inversely proportional to wavelength (E ∝ 1/λ).
Answer:
Permeable.
Explanation:
Most sediments of a chalky quality are permeable.
Energy is released during the reaction and is captured by the energy-carrying molecule ATP (adenosine triphosphate).
Answer:
The correct option is;
C. Two in the first energy level, six in the second energy level
Explanation:
The electrons in an atom are arrange in orbital shells which are situated at different levels within the structure of the, depending on the energy of the electron. Electrons with the least amount of energy are found in the shell closest to the nucleus of the atom which is the first energy level
The maximum number of electrons that can be found in a given an energy level is obtained with the following formula;
The number of electron = 2 × n²
Where;
n = The number of the different energy level
Therefore;
The maximum number of electrons in the first energy where n = 1 is given as follows;
The number of electron = 2 × 1² = 2 electrons
The maximum number of electrons in the second energy level where n = 2 is given as follows;
The number of electron = 2 × 2² = 8 electrons
Given that there are only 8 electrons in the atom, we therefore have, 2 electrons in the first energy level and the remaining 8 - 2 = 6 electrons in the second energy level.
The answer is B. uniform in composition.
