What is Hertz formula? We denote frequency by Frequency is measured in Hertz = Hz = 1/seconds. If a wave with a wavelength of 2 meters is going by at a speed of 6 meters/second, then 3 complete waves go by in 1 second. That is, the frequency is 6/2 = 3 waves/second, or 3 […]

Which is the most common type of fingerprint pattern?
Which is the most common type of fingerprint pattern? Loop Does each finger have a different fingerprint? Yes, it is common to have different patterns on the fingers of one hand. The reason is because each finger develops individually. During fetal development, factors across the surface of each finger determine how the ridges will align. […]
What are the two types of kinetic friction?
What are the two types of kinetic friction? In general, the friction is of the following two types: (1) Static friction. It is the friction, experienced by a body, when at rest. (2) Dynamic friction. It is the friction, experienced by a body, when in motion. (a) Sliding friction. (b) Rolling friction. (c) Pivot friction. […]
What is heat What are the various sources of heat?
What is heat What are the various sources of heat? The heat energy which is obtained from earth is called geothermal energy. It can be found in hot water and rocks present underground. Heat is also found in the form of molten rocks and magma, deep inside the Earth’s crust. Air is also an important […]
Why are fossils so important?
Why are fossils so important? Fossils of any kind are useful in “reading the rock record,” meaning they help us decipher the history of the earth. They can help us determine the geologic age and environment (the paleoenvironment) in which they were deposited. What are the five types of fossils? Five different types of fossils […]
How much pollution does energy produce?
How much pollution does energy produce? It’s a significant body of data given that power generation accounts for about a quarter of global carbon dioxide emissions at 10 billion tonnes per year. Over a quarter of that comes from the 8000 power plants in the United States, making its energy sector the biggest carbon emitter […]
