What are 10 sources of energy? What are Different Alternative Sources of Energy? Solar Energy. Wind Energy. Geothermal Energy. Hydrogen Energy. Tidal Energy. Wave Energy. Hydroelectric Energy. Biomass Energy. What causes dirty energy? Dirty power originates outside of and within your facility. Sources like lightning, utility switching, capacitor switching, and faults on the utility’s distribution […]

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 […]

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. […]

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 […]

What is needed for an ecosystem to support the greatest variety of organisms? Answer: An ecosystem must contain producers, consumers, decomposers, and dead and inorganic matter. All ecosystems require energy from an external source – this is usually the sun. Plants need sunlight to photosynthesize and produce glucose, providing an energy source for other organisms. […]

What is the black thing on a guitar called? The Soundhole: Most acoustic guitars have a sound hole in the middle of the guitar, though some guitars may have the sound hole in a different spot or not have one at all. The Bridge: The black part of the guitar on the other end of […]

How do you find distance rate and time problems? The formula for distance problems is: distance = rate × time or d = r × t. Things to watch out for: Make sure that you change the units when necessary. For example, if the rate is given in miles per hour and the time is […]

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 […]
