What is the relationship between the average kinetic energy of a gas particle and temperature? The average kinetic energy of the particles in a gas is proportional to the temperature of the gas. Because the mass of these particles is constant, the particles must move faster as the gas becomes warmer. What is the relationship […]

How fast do gymnasts rotate?
How fast do gymnasts rotate? 0.6 rotations per second Why does a gymnast stay balanced on a beam? When standing straight up, gravity is acting on the gymnast but the gymnast is able to stay relatively stable because her center of mass is directly above the beam which means that gravity is pushing her down […]
Is friction an impulsive force?
Is friction an impulsive force? The frictional force is considered an impulsive force only in cases when the friction is proportional to the normal force. Is normal force an impulsive force? We consider friction to an impulsive force, in cases when normal force is impulsive. Therefore, in your question, since normal is impulsive in case […]
How much radiation does the sun emit?
How much radiation does the sun emit? Sources indicate an “Average over the entire earth” of “164 watts per square meter over a 24-hour day”. The ultraviolet radiation in sunlight has both positive and negative health effects, as it is both a requisite for vitamin D3 synthesis and a mutagen. Where is solar radiation highest […]
What is high and low concentration?
What is high and low concentration? High concentration means the amount of solute is high in the solution and low concentration means it is low. Amount of solvent is high in low concentration and low in high concentration of solute. What is the meaning of higher concentration? concentration Add to list Share. A high concentration […]
Does Aluminium react with iron?
Does Aluminium react with iron? 1 Answer. Aluminium reacts with iron(III) oxide because it can be considered to be more reactive than iron so will remove oxygen from the iron(III) oxide. Is making thermite illegal? Thermite has many legitimate uses in industry, such as welding railroad tracks and construction/demolition work. Many sites sell thermite ingredients […]
Is calcite a positive crystal?
Is calcite a positive crystal? Calcite. Calcite is a uniaxial hexagonal-rhombohedral mineral with moderate refractive index, but extreme birefringence. It is so birefringent that it appears to have both negative and positive relief, depending on orientation. Calcite is most common in marine environments, and other sedimentary-processes rocks. What causes double refraction in calcite? Birefringence is […]
