Do magnetic lines of force really exist?
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 […]
What do all metals have in common?
What do all metals have in common? All metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metals; and have at least one basic oxide. What property do most metals share? In addition to conducting electricity, many metals have several other shared properties, […]
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 […]
What are some names for heart problems?
What are some names for heart problems? Angina. Arrhythmias. Atrial fibrillation. Atrial flutter. Cardiac arrest. Coronary heart disease. Dilated cardiomyopathy. Heart attack. What is a normal heart rate called _? Your pulse is measured by counting the number of times your heart beats in one minute. For example, if your heart contracts 72 times in […]
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 […]
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 […]
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 […]
