Waves Mastery Quest Regrade - 3/7/18

1.) What is the measure of how many waves pass a point in a certain amount of time?

The correct answer to this question is frequency. The difference between frequency and wavelength is that frequency measures how many waves pass a point in a certain amount of time, while wavelength is the distance between successive crests of a wave.

3.) A _____________________ is the distance between a point on one wave and the identical point of the next wave.

The correct answer to this question is wavelength. The difference between wavelength and amplitude is that one measures distance, while one is the maximum extent. Wavelength is the distance between successive crests of a wave, while amplitude is the maximum extent of a vibration.

6.) Which of the following is the state of matter that will carry sound faster?






The correct answer to this question is solids. This is because their molecules are the closest together, so they can transfer the sound waves without losing energy.

12.)Amplitude reflects the amount of ____________________ in a wave.

The correct answer to this question is energy. The reason that energy is the correct answer is that the amount of energy carried by a wave is related to the amplitude of the wave. A high energy wave is characterized by a high amplitude, while a low energy wave is characterized by a low amplitude.

19. Cell phones use_____________waves.

The correct answer to this question is that cell phones use microwaves. This is the correct answer because cell phones transmit and receive on microwave bands.

21.) Amplitude is a measure of how much _________ the wave is carrying.

The correct answer to this question is energy. The reason that energy is the correct answer is that you want to be able to know the intensity or brightness of a wave so you can determine which wave is which.

Amedeo Avogadro - 5/27/18

Image
Summary : Amedeo Avogadro was an Italian scientist who created what is now known as Avogadro's law. Known as a founder of the atomic-molecular theory, he was the first scientist to realize that elements could exist in the form of molecules rather than as individual atoms. His biggest contribution to science, Avogadro’s law, states that equal volumes of gasses under the same conditions of pressure and temperature will contain an equal number of molecules. Amedeo Avogadro was born on August 9th 1776 to Filippo Avogadro and Anna Maria Vercellone. Coming from a family of lawyers, Advogadro was guided to a legal career, and became a bachelor of jurisprudence in 1792. Despite a successful legal career; Avogadro has started private studies of mathematics and physics, which then he pursued full time. SP8 - Communicating Information : This week, I communicated information in the form of a wanted poster about a certain scientist. I decided to create a wanted poster about Am...

Roller Coaster Project Blog - 2/18/18

Summary : A roller coaster ride is a thrilling experience which involves a lot of physics. Part of the physics of a roller coaster is the physics of work and energy. The ride often begins as a chain and motor which exerts a force on the train of cars to lift the train to the top of a vary tall hill. Once the cars are lifted to the top of the hill, gravity takes over and the remainder of the ride is an experience in energy transformation. At the top of the hill, the cars possess a large amount of potential energy. Potential energy is dependent upon the mass of the object and the height of the object. As the cars descend the first drop they lose much of this potential energy in accord with their loss of height. The cars subsequently gain kinetic energy. Kinetic energy is dependent upon the mass of the object and the speed of the object. Therefore, their original potential energy is transformed into kinetic energy. Backward-Looking:  How much did you know about the subject befor...

The Designer Species Project - Project Blog 11/5/17

Summary: The Fobra is a new species of frog with the body of a red-eyed tree frog, the eyes of an owl, the fangs of a king cobra, and the claws of a squirrel. Since the fobra lives in planet C, a tropical planet with much rainforest and vegetation, our frog can "nest" itself in the plants to stay warm. To stay cool the fobra can soak itself in puddles and absorb the moisture. The fobra is also a warm-blooded animal. The fobra uses both its tongue and teeth to eat, depending on the size of animal it is eating. With the claws similar to squirrels, the fobra will be able to get away and climb up on trees faster, making predators unable to get it. As well having the bite similar to the king cobra, our species will bite predators when it feels threatened or scared by predators that are after them. The fobra will be able to strike extremely quickly, like a cobra, in self-defense. Red-eyed tree frogs will lay clutches of eggs on the underside of leaves that are standing abo...
