Answer:
Energy consumed by each person = 161.5 kWh
Explanation:
Given:
Total energy used = 646 kWh
Total number of person = 4 hour
Find:
Energy consumed by each person
Computation:
Energy consumed by each person = Total energy used / Total number of person
Energy consumed by each person = 646 / 4
Energy consumed by each person = 161.5 kWh
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.

The start of the American Revolution began because:
Americans wanted independence but, the British didn't let them have it so they had a fight. America won and then the people wrote the declaration of independence. And The American Revolution started mainly because of these reasons:
1) The colonists were being taxed, but they had no representation in Parliament. They could no agree or disagree to any laws, they had no say on HOW to tax the colonists, and more. It was a very... frustrating thing.
2) British troops were being quartered at the colonists' homes. Imagine if you were doing your daily job in the morning, and suddenly and unknown soldier bursts into your house claiming that he was quartered here and you had to provide him with a room, food, and clothing.
3) England wanted strict control over colonial legislatures. That means that if England did this, than the colonies would have no say, what-so-ever in what laws are being made for their OWN country.
4) Some colonists resented the power of colonial governors. A governor was placed in every colony. The colonists thought that the governor perhaps had TOO much power.
5) The Proclamation of 1763 hampered the western movement of settlers. This proclamation banned all settlers the freedom to move west. Things were getting crowded at the colonies and they had no choice but to move west. But this document prevented that.
That is how it was started
