What are the main components of fiber optic cabling? A fiber optic cable consists of five main components: core, cladding, coating, strengthening fibers, and cable jacket. Core: This is the physical medium that transports optical signals from an attached light source to a receiving device. How fast is multimode fiber? 100 Mbit/s How do I […]
How do you calculate the rms speed of hydrogen?
How do you calculate the rms speed of hydrogen? RMS speed is inversely proportional to the square root of mass (molecular or molar). This means the rms speed of hydrogen should be √16 = 4 times faster….solution. vHg = √3kTHg/mHg vH2 √3kTH2/mH2 What is K in Vrms? Speed V of the molecules of an ideal […]
Which brain region would be most difficult to survive without?
Which brain region would be most difficult to survive without? In the words of researcher and neurologist Jeremy Schmahmann, it’s the “Rodney Dangerfield of the brain” because “It don’t get no respect.” It’s the cerebellum. Even though the cerebellum has so many neurons and takes up so much space, it is possible to survive without […]
What are examples of learned behaviors?
What are examples of learned behaviors? Simple learned behaviors For example, prairie dogs typically sound an alarm call when threatened by a predator. Imprinting is a simple and highly specific type of learning that occurs at a particular age or life stage during the development of certain animals, such as ducks and geese. Are all […]
What makes evidence empirical?
What makes evidence empirical? Empirical evidence is information acquired by observation or experimentation. Scientists record and analyze this data. What is the opposite of empirical knowledge? Empirical Knowledge is knowledge gained and/or Justified through experience, so the opposite is anything known not gained or justified through experience; A Priori Knowledge: Claims which are known (and […]
How do you find the fundamental period?
Can a single element be a mineral?
Can a single element be a mineral? Minerals made of only one element are called NATIVE minerals (i.e., silver, gold, mercury, copper). Minerals composed of compounds are simply referred to as minerals (i.e., quartz, which is made up on silicon and oxygen). What’s the difference between an element and a mineral? Minerals are made up […]
What are the five types of mechanical weathering?
What are the five types of mechanical weathering? There are five major types of mechanical weathering: thermal expansion, frost weathering, exfoliation, abrasion, and salt crystal growth. What are the factors that are common in mechanical and chemical weathering? Mechanical/physical weathering – physical disintegration of a rock into smaller fragments, each with the same properties as […]
What absorbs heat from the sun?
What absorbs heat from the sun? Materials that absorb sunlight well include dark surfaces, water and metal. The sun’s light energy arrives as a mixture of visible light, ultraviolet and infrared; some materials absorb all these wavelengths well, while others are better suited to a certain restricted types of light. Does oil hold heat longer […]
What is the major function of the muscle tissue?
What is the major function of the muscle tissue? The muscular system’s main function is to allow movement. When muscles contract, they contribute to gross and fine movement. Gross movement refers to large, coordinated motions and includes: walking. What is the difference between voluntary and involuntary muscles? involuntary: A muscle movement not under conscious control […]
