What is the difference between absorption and reflection? Reflection means that they are thrown back from a surface; absorption means that they are incorporated by a surface and transformed into heat energy. Different surfaces reflect and absorb differently. The ratio between absorption and reflection is called albedo. What is P in Beer’s law? Absorption takes […]

Does aluminum or lead have a greater buoyant force?
Does aluminum or lead have a greater buoyant force? Insight: Although each sphere experiences the same buoyant force, the lead sphere is more massive than the aluminum sphere and therefore the lead sphere still weighs more while submerged than does the aluminum sphere. Is lead buoyant? The specific gravity of lead is 11.34 – which […]
What is the significance of quantum number?
What is the significance of quantum number? Quantum numbers are important because they can be used to determine the electron configuration of an atom and the probable location of the atom’s electrons. Quantum numbers are also used to understand other characteristics of atoms, such as ionization energy and the atomic radius. Which of the following […]

What is a sample space diagram?
What is a sample space diagram? A sample space diagram is a maths table showing all the possible outcomes or results of events. It is used for probability questions. For example, the sample space of flipping a coin is heads or tails! What is possibility diagram? A Probability Space Diagram, or Sample Space Diagram, shows […]
What is the homogeneous product?
What is the homogeneous product? A homogeneous product is one that cannot be distinguished from competing products from different suppliers. In other words, the product has essentially the same physical characteristics and quality as similar products from other suppliers. One product can easily be substituted for the other. What is homogeneous and differentiated products? 1. […]
Does the initial velocity affect acceleration?
Does the initial velocity affect acceleration? Initial velocity is independent of the slope of the graph; that is, the acceleration. Does a heavier object hit the ground first? In other words, if two objects are the same size but one is heavier, the heavier one has greater density than the lighter object. Therefore, when both […]
What are the problems that cause and effects of ozone depletion?
What are the problems that cause and effects of ozone depletion? Effects of ozone depletion for humans and the environment Ozone layer depletion causes increased UV radiation levels at the Earth’s surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders. How […]
Is it possible to cure myopia naturally?
Is it possible to cure myopia naturally? Myopia can be cured: MYTH Once this excessive eye growth has commenced, we can attempt to slow it down with myopia control treatments but we can’t stop the eyes from growing or reverse the excessive growth.
