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.
Answer:
Hinduism reinforced a strict social hierarchy called a caste system that made it nearly impossible for people to move outside of their social station.
Explanation:
Hinduism reinforced a strict social hierarchy called a caste system that made it nearly impossible for people to move outside of their social station. Emperors during the Gupta empire used Hinduism as a unifying religion and focused on Hinduism as a means for personal salvation.
B. Piaget’s theory of cognitive development begins in the sensorimotor stage, where children are still making sense of the world through their senses, and ends in the formal operational stage, in which a person begins to think abstractly and reason about hypotheticals.
Answer:
Following major earthquake, a 15- metre tsunami disable the power supply and cooling of three Daiichi reactors, causing a nuclear accident being on March 11, 2011. All three cords largely melted in the first three days.

Check below for answers and explanations
Explanation:
a) Crystallized intelligence is a form of knowledge that is garnered from past experiences or adequate study. Lucy has previously worked in the library as a high school student before going there for the volunteering service. The experiences she has gotten from her past works in the library will be deployed into her current program for a successful outcome.
b) Alrtruism is a philosophical term that describes the concern of an individual for the well-being of others. Lucy's volunteering service that is targeted at assisting disadvantaged children is a proof of her altruistic lifestyle.
c)The Big five trait of extraversion describes how sociable a personality is. While Lucy was walking in her community library, a good number of children visited, her return to the library to organize a program for children proves that she loves being around and socializing with children.
d) The Broca's area is a part of the brain that plays a vital role in producing and understanding speeches. For Lucy to organize such a developmental program like this, she must be very eloquent with an admirable leadership skills. Her ability to even attend to library users as a high school student is a proof that she has a sound oratory prowess.
e) Self efficacy is the ability to control one's actions and deal with situations that require critical decision making. Lucy's decision to leave a paid job that doesn't give her satisfaction for a volunteering program in the library is an attribute of self efficacy.
f) Episodic memory is the process of bringing back and combining past experiences and events. Lucy recalled how much she enjoyed working at the library and decided to return there.
g) Self actualization is a fulfilment of one's dreams and goals. Lucy's return to the Library is like bringing back the sweet work experiences she once had. This indeed is self actualization.
