Is buoyant force constant? Because the volume is the same at any depth, and the density of water is the same at any depth, the total mass of displaced water (mass = volume x density) is the same at any depth—making the buoyant force constant. Why is a heavier object more likely than a lighter […]
Are we made of waves?
Are we made of waves? Radio waves are obviously waves. Only when we come close do we notice that this object is actually a wave. Summary: With quantum theory, we find a beautiful unification: instead of there being two fundamental entities (particles and waves), there is only one fundamental entity: waves. Does Matter diffract? All […]
What is the reason that air tanks must be drained?
What is the reason that air tanks must be drained? To prevent too much moisture and oil from collecting, the air tanks must be drained regularly. Air pressure gauges indicate air pressure in the vehicle’s dual service (primary and secondary) air tanks. Safety valves prevent over-pressure of the air brake system. Why must air tanks […]
Can high voltage low current kill you?
Can high voltage low current kill you? No, it’s the current that kills you. It kills you by putting a current signal through your heart, which interferes with its normal operation. The high voltage is necessary to penetrate the skin. How many volts can Denki produce? This move was first used against members of the […]
What is the relationship between valence electrons and bonding?
What is the relationship between valence electrons and bonding? Valence electrons are outer shell electrons with an atom and can participate in the formation of chemical bonds. In single covalent bonds, typically both atoms in the bond contribute one valence electron in order to form a shared pair. The ground state of an atom is […]
Is pitch and note the same?
What are five ways to make an observation?
What are five ways to make an observation? Explain that an observation is information we gather about something by using our senses. List the five senses of sight, hearing, taste, touch, and smell. Use their senses to make observations about things in the classroom. What are the direct observation methods? Observations can also be either […]
