Why does a hollow sphere have more rotational kinetic energy? Another hollow sphere of the same mass and radius is rotating about its axis through the center at the same rotation rate. Which sphere has a greater rotational kinetic energy? The hollow sphere, since the mass is distributed further away from the rotation axis. Does […]
Is magnetic energy a form of energy?
Is magnetic energy a form of energy? Each magnetic field contains energy, also called magnetic energy. She is a constant in physics. Because a magnetic field is generated by electric currents, the magnetic energy is an energy form of moving charge carriers (electrons). What kind of energy is magnetic energy? Moving a magnet around a […]
What is the average wpm for a 13-year-old?
What is the lifespan of a hurricane?
Is phenolphthalein pink in acid?
Is phenolphthalein pink in acid? Phenolphthalein is often used as an indicator in acid–base titrations. For this application, it turns colorless in acidic solutions and pink in basic solutions. What is a scale used to describe how acidic or basic a solution is? pH. This is the scale used to describe how acidic or basic […]
What is the effect of the Gulf Stream of Europe?
What is the effect of the Gulf Stream of Europe? Since the Gulf Stream also extends toward Europe, it warms western European countries as well. In fact, England is about the same distance from the equator as cold regions of Canada, yet England enjoys a much warmer climate. If it weren’t for the warm water […]
What is the Doppler effect and why is it important?
What is the Doppler effect and why is it important? The Doppler effect is important in astronomy because it enables the velocity of light-emitting objects in space, such as stars or galaxies, to be worked out. What are two everyday applications of the Doppler effect? The Doppler effect has several real-world applications. For example, besides […]
Where is the thickest loess deposits found?
Where is the thickest loess deposits found? Extensive loess deposits are found in northern China, the Great Plains of North America, central Europe, and parts of Russia and Kazakhstan. The thickest loess deposits are near the Missouri River in the U.S. state of Iowa and along the Yellow River in China. Is Loess erosional or […]
Is gravitational force equal to weight?
Is gravitational force equal to weight? The gravitational force on Earth is equal to the force the Earth exerts on you. At rest, on or near the surface of the Earth, the gravitational force equals your weight. What two factors does gravitational force depend on? When dealing with the force of gravity between two objects, […]
Is called autonomous unit of life?
Is called autonomous unit of life? The cell is known as the autonomous unit of life because it can independently carry out all the life activities necessary for its own survival. A cell has absolute independent existence. Why cell is called self-contained unit? The cell whether in a unicellular organism or a multicellular organism is […]
