Answer: See explanation
Explanation:
A physical quantity is a quantity that an individual can measure and it also has a unit. Examples of some physical measurement and their corresponding units include:
• Time = Seconds
• Length = Meter
• Mass = Kilogram
• Electric current = Ampere
• Temperature = Kelvin

The correct answer to this open question is the following.
You forgot to attach the text, the argument, and the options for this question. However, doing some research, we can say the following.
The argument in the second paragraph of the inscription regarding king Adityawarman is about how his spiritual attributes and worldly achievements made him a respected, powerful, and effective ruler.
Historians say that he was a strict but good ruler of the Kingdon of Malayapura, is Sumatra, in Southeastern Asia.
Deeper research on the part of historians has found that he had deep spiritual belief systems that made him a compassionate ruler too, and people respect him for that.
The given angles sum to less than 90°, so the remaining angle must be more than 90°. (The total of all angles is 180°.) Triangle ABC has an angle greater than 90°, so is obtuse. Since the triangles are similar, their corresponding angles are congruent. Hence ...
.. D. Triangle XYZ is obtuse.
Answer:
Visible Light Absorption
Atoms and molecules contain electrons. It is often useful to think of these electrons as being attached to the atoms by springs. The electrons and their attached springs have a tendency to vibrate at specific frequencies. Similar to a tuning fork or even a musical instrument, the electrons of atoms have a natural frequency at which they tend to vibrate. When a light wave with that same natural frequency impinges upon an atom, then the electrons of that atom will be set into vibrational motion. (This is merely another example of the resonance principle introduced in Unit 11 of The Physics Classroom Tutorial.) If a light wave of a given frequency strikes a material with electrons having the same vibrational frequencies, then those electrons will absorb the energy of the light wave and transform it into vibrational motion. During its vibration, the electrons interact with neighboring atoms in such a manner as to convert its vibrational energy into thermal energy. Subsequently, the light wave with that given frequency is absorbed by the object, never again to be released in the form of light. So the selective absorption of light by a particular material occurs because the selected frequency of the light wave matches the frequency at which electrons in the atoms of that material vibrate. Since different atoms and molecules have different natural frequencies of vibration, they will selectively absorb different frequencies of visible light.
