Do magnetic lines of force really exist? To describe the phenomena related to magnets, lines are used to depict the force existing in the area surrounding the magnet. These lines are called the magnetic lines of force. These lines do not exist actually, but are imaginary lines that are used to illustrate and describe the […]
How do you calculate projectile distance?
How do you calculate projectile distance? The equation for the distance traveled by a projectile being affected by gravity is sin(2θ)v2/g, where θ is the angle, v is the initial velocity and g is acceleration due to gravity. Assuming that v2/g is constant, the greatest distance will be when sin(2θ) is at its maximum, which […]

Which would be her first step in balancing an equation?
Which would be her first step in balancing an equation? The first step in balancing a chemical equation is to identify your reactants and your products. Remember, your reactants are on the left side of your equation. The products are on the right side. Why does his teacher ask him to balance the equation by […]
Does Gypsum react to hydrochloric acid?
Does Gypsum react to hydrochloric acid? Does Gypsum react to hydrochloric acid? Gypsum is very soft (softer than a fingernail and so can be scratched by a fingernail). It’s color is typically clear or white, but can take on color from impurities, such as pink or yellow. It will not effervesce (fizz) in dilute HCl […]
Did saber tooth tigers eat humans?

However, there no such evidence that suggests that saber tooth tiger ate humans. What eats a saber tooth tiger? Saber-Toothed Tigers preyed on deer, bison, and woolly mammoths. What were some […]
What is the process of changing gas to solid?
What is the process of changing gas to solid? Deposition is the phase transition in which gas transforms into solid without passing through the liquid phase. Deposition is a thermodynamic process. The reverse of deposition is sublimation and hence sometimes deposition is called desublimation. What are the types of solid solution? There are two classes […]
Is Metal a good insulator?
Is Metal a good insulator? Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. Metals are also generally good heat conductors while nonmetals are not. Which metal is the best insulator? As you can see, out of […]
What is antagonistic action?
What is antagonistic action? The ability of a drug or a muscle to oppose or resist the action or effect of another drug or muscle; opposite of synergistic action. See also: action. What is an example of antagonistic effect? An example of antagonistic effect is the effect between the opposing actions of insulin and glucagon […]
