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 kind of a wave is sound?
What kind of a wave is sound? These particle-to-particle, mechanical vibrations of sound conductance qualify sound waves as mechanical waves. Sound energy, or energy associated with the vibrations created by a vibrating source, requires a medium to travel, which makes sound energy a mechanical wave. How ECHO is created? An echo is made by sound […]
What are 3 uses of beryllium?
What are 3 uses of beryllium? Beryllium is alloyed with copper or nickel to make springs, gyroscopes, electrical contacts, spot-welding electrodes and non-sparking tools, according to the Royal Society of Chemistry. Other beryllium alloys are used in high-speed aircrafts and missiles, as well as spacecraft and communication satellites. Why is beryllium so expensive? Beryllium is […]
What is the difference between absorption and reflection?
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 […]

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 […]
How can you protect an organism?
How can you protect an organism? Here are some tips: Make sure you don’t throw toxic, or harmful, materials in the trash, like paint or car batteries. Don’t take super long showers or let water run when you aren’t using it. Don’t drink from plastic water bottles. Don’t have wild animals as pets. Don’t depend […]
What 3 components make up most magmas?
What 3 components make up most magmas? Magmas can vary widely in composition, but in general they are made up of only eight elements; in order of importance: oxygen, silicon, aluminum, iron, calcium, sodium, magnesium, and potassium (Figure 3.6). Which component of magma is the highest in value? Felsic magma has the highest silica content […]
