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:
Electronic measurement tools accurately store a large volume of data very quickly.
Explanation:
Electronic measurement tools are important devices used in taking records of data. They are very good measuring tools because they can measure a large amount of data very quickly and in a very precise manner. Examples include; multimeters, voltmeters, oscilloscopes, etc.
Their sizes might vary but a general attribute to them all is the speed at which data is recorded and the precision with which they are measured. Scientists most times use these devices to take measurements.

Explanation:
By solving the equation we get the following graph
Explanation:
primero pasas al goat, después regresas y pasas el cabbage pero solo dejas el cabbage y te traes el goat. regresas por el wolf y dejas al goat solo y pasas al wolf y lo dejas con el cabbage y ya después bien tranquilo vienes por tu goat y listo te vas dónde el wolf y el cabbage
When capsaicin – the chemical in spicy foods that makes them so hot, Hot, HOT – hits your tongue, your body registers the sensation as pain. This in turn triggers the release of endorphins, otherwise known as “happy” chemicals that give you an instant head-to-toe feeling of pleasure.
