What are the natural causes of extinction?
What are the natural causes of extinction? Extinction occurs when species are diminished because of environmental forces (habitat fragmentation, global change, natural disaster, overexploitation of species for human use) or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers). What’s the difference between extinction and mass extinction? Background extinction […]
Which liquid marble flows the fastest slowest?
Which liquid marble flows the fastest slowest? We expect that the marble will travel the slowest through honey, the fastest through water, and the time for oil will be somewhere in between. Drop a marble into each jar one at a time, starting with honey, then water, and lastly the oil. Why is glass called […]
Why Oxygen is a diatomic element?
How do I calculate the coefficient of friction?
How do I calculate the coefficient of friction? The formula to calculate the coefficient of friction is μ = f÷N. The friction force, f, always acts in the opposite direction of the intended or actual motion, but only parallel to the surface. What is the coefficient of friction for steel? The coefficient of static friction […]

How do you show the movement of electrons?
How do you show the movement of electrons? Using curly arrows to show the movement of single electrons The most common use of “curly arrows” is to show the movement of pairs of electrons. You can also use similar arrows to show the movement of single electrons – except that the heads of these arrows […]

What devices use superconductors?
What devices use superconductors? Superconducting devices are used for highly sensitive optical sensors, detectors of magnetic fields and low-noise amplifiers. Superconducting circuits are one possible type of qubit, the building blocks of quantum computers. Can Superconductors be used in daily life working? Most chemical elements can become superconductors at sufficiently low temperatures. Levitating trains, highly […]
How does an emission spectrum work?
How does an emission spectrum work? An atomic emission spectrum is the pattern of lines formed when light passes through a prism to separate it into the different frequencies of light it contains. Each of these spectral lines corresponds to a different electron transition from a higher energy state to a lower energy state. What […]
