Is any closed conducting path? There must be a closed conducting loop from the positive to the negative terminal in order to establish a circuit and to have a current. When this occurs, the circuit is opened and a closed conducting loop no longer exists. Without a closed conducting loop, there can be no circuit, […]
What are some of the examples of exceptions to the patterns of our solar system?
What are some of the examples of exceptions to the patterns of our solar system? Exceptions to the rules: The generally orderly solar system also has some notable exceptions. For example, among the inner planets only earth has a large moon, and Uranus is tipped on it’s side. A successful theory must make allowances for […]
Has a hurricane ever hit Mississippi?
Has a hurricane ever hit Mississippi? 1969: Hurricane Camille Hurricane Camille is one of just four Category 5 storms to make landfall in the continental United States, according to the National Weather Service. The storm made landfall near Waveland, Mississippi, in August 1969. Storm surge reached almost 25 feet in parts of Mississippi. What was […]
What is stream function and velocity potential?
What is stream function and velocity potential? Introduction. The stream function, ,, is a function specially suited for dealing with two- dimensional flow while the velocity potential, f, is a function which may be. used with either two- or three-dimensional flow. What is unit for flow rate for gases? Because of this, meter flow rates […]
What are the characteristics of seedless vascular plants?
What are the characteristics of seedless vascular plants? Seedless vascular plants include ferns, horsetails and clubmosses. These types of plants have the same special tissue to move water and food through their stems and foliage, like other vascular plants, but they don’t produce flowers or seeds. Instead of seeds, seedless vascular plants reproduce with spores. […]
What evidence does the fossil record provide?
What evidence does the fossil record provide? Fossils document the existence of now-extinct species, showing that different organisms have lived on Earth during different periods of the planet’s history. They can also help scientists reconstruct the evolutionary histories of present-day species. Why are fossils so hard to find? Fossils are rare because their formation and […]
Is tea a colloid suspension or solution?
Why the motion of pendulum will not be a simple harmonic motion?
Why the motion of pendulum will not be a simple harmonic motion? Any pendulum undergoes simple harmonic motion when the amplitude of oscillation is small. The pendulum still oscillates, but the motion is no longer simple harmonic motion because the angular acceleration is not proportional to the negative of the angular displacement. Why is the […]
Which solid has the highest melting point?
Which solid has the highest melting point? tungsten Do impurities lower melting point? The presence of even a small amount of impurity will lower a compound’s melting point by a few degrees and broaden the melting point temperature range. Because the impurity causes defects in the crystalline lattice, it is easier to overcome the intermolecular […]
Who is the father of atom?
Who is the father of atom? Basic Atomic Structure. The idea that everything is made of atoms was pioneered by John Dalton (1766-1844) in a book he published in 1808. He is sometimes called the “father” of atomic theory, but judging from this photo on the right “grandfather” might be a better term. How thick […]
