What do you notice about the iron filings? All magnets show properties of magnetic attraction and repulsion. With the use of iron filings, we can see these magnetic fields. When iron filings are sprinkled on a bar magnet, you see that these magnetic field lines start at the magnet’s north end and will end at […]
Do electrons move in their orbitals?
Do electrons move in their orbitals? Because an electron is a quantum object with wave-like properties, it must always be vibrating at some frequency. Furthermore, an electron in a stable atomic state does not move in the sense of waving through space. The orbital electron does move in the sense of vibrating in time. Can […]

What best describes white light after it passes through a prism?
What best describes white light after it passes through a prism? Visible light, also known as white light, consists of a collection of component colors. Upon passage through the prism, the white light is separated into its component colors – red, orange, yellow, green, blue and violet. The separation of visible light into its different […]
How many volts is 2000 watts?
How does volume affect rms speed?
How does volume affect rms speed? Since the temperature is remaining constant, the average kinetic energy and the rms speed remain the same as well. The volume of the container has decreased, which means that the gas molecules have to move a shorter distance to have a collision. What is the rms speed? The root-mean-square […]
What happens to the molecules of water when it freezes?
What happens to the molecules of water when it freezes? Point out that when water freezes, the water molecules have slowed down enough that their attractions arrange them into fixed positions. Water molecules freeze in a hexagonal pattern and the molecules are further apart than they were in liquid water. Note: The molecules in ice […]
What are the causes of shortage of electricity?
What are the causes of shortage of electricity? There are many causes of power failures in an electricity network. Examples of these causes include faults at power stations, damage to electric transmission lines, substations or other parts of the distribution system, a short circuit, cascading failure, fuse or circuit breaker operation. Why electricity is harmful? […]
