How does a slope affect erosion? Erosion moves soil and other particles. With more force, water can move more rock particles and larger ones. The speed at which water flows downhill is directly affected by the slope, or steepness, of the land. The steeper the slope, the faster the water flows downhill, and the greater […]

What is used to balance a chemical equation? Coefficients How do you balance a math equation step by step? Combining the operations Add the same amount to both sides (either x’s or ones) Subtract the same amount from both sides (either x’s or ones) Multiply both sides by the same number (but not by zero) […]

What note is 7.83 Hz? When converted into sound waves, 7.83 is a flat “B-2” (two octaves below the lowest note on a piano). It is also the keynote to which Nikola Tesla tuned the Noth American Power Grid. The electric powers hums at 60 hz, the ninth overtone of the Earth, and loudest note […]

Why is a Tesseract 4 dimensional? A tesseract (also known as a hypercube) is a four-dimensional mathematical object with lines of equal length that meet each other at right angles. It is the extension of the square to a four-dimensional space in the same way that a cube is the extension of the notion of […]

Are there sharks in the English Channel? “Porbeagles are present in UK waters the whole year round,” says Richard Peirce, author of Sharks in British Seas, conservationist and former chairman of the Shark Trust. “They are cousins of the great white and mako – and all of these sharks can regulate their body temperature above […]

What comes first in a primary succession? Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such […]

Who gave the theory of natural selection? Charles Darwin What animals go through natural selection? Deer Mouse. Warrior Ants. Peacocks. Galapagos Finches. Pesticide-resistant Insects. Rat Snake. All rat snakes have similar diets, are excellent climbers and kill by constriction. Peppered Moth. Many times a species is forced to make changes as a direct result of […]

How do you measure the volume of a banana? Half of the widest diameter of the banana will be your radius (r). Now divide the length of the banana in half. The length/2 is the hight of the cone. So half the volume of the banana is 1/3 pir squaredh. Does a banana have volume? […]

Why was the geocentric model of the solar system accepted by scientists for many years select the two correct answers? Answer: Because of the its assumption of earth being at the centre of the universe and also, its parallax argument. The ancient Greeks claimed that if the Earth is moving around the Sun then the […]
