How often does aurora australis occur? Most southern lightshows occur during the Southern Hemisphere’s fall and winter months, which stretch from March through September. Here are four aurora australis hotspots for those looking for a southern celestial spectacle. What are the two most common and two most rare colors seen in auroras? The colors most […]
Why do electrons want to be stable?
Why do electrons want to be stable? A complete octet is very stable because all orbitals will be full. Atoms with greater stability have less energy, so a reaction that increases the stability of the atoms will release energy in the form of heat or light. A stable arrangement is attended when the atom is […]
Is inhaling helium bad?
Is inhaling helium bad? The more pure helium you inhale, the longer your body is without crucial oxygen. Breathing in pure helium can cause death by asphyxiation in just minutes. Inhaling helium from a pressurized tank can also cause a gas or air embolism, which is a bubble that becomes trapped in a blood vessel, […]

Here are those: Always use a UPS. If you stay in an area which has a problem of high-intensity […]
Can coefficient of drag be greater than 1?
Can coefficient of drag be greater than 1? Two objects having the same reference area moving at the same speed through a fluid will experience a drag force proportional to their respective drag coefficients. Coefficients for unstreamlined objects can be 1 or more, for streamlined objects much less. Does drag coefficient change with size? The […]
Where are water masses formed?
Where are water masses formed? Water masses are formed as the result of climatic effects in specific regions. Antarctic bottom water is an important water mass that forms on the Antarctic continental shelf as a cold, dense residual brine during the formation of sea ice. Which water mass is the saltiest in the world? That […]
How is charge transfer calculated?
How is charge transfer calculated? Measurements of charge transfer may be made either measuring the voltage developed across a capacitor to earth, instead of the resistor, or using a virtual earth charge measurement amplifier. Another approach is to integrate discharge current flow measurements over the duration of the discharge. Can you transfer battery power from […]
Does falling snow absorb sound?
Does falling snow absorb sound? When the ground has a thick layer of fresh, fluffy snow, sound waves are readily absorbed at the snow surface, dampening sound. However, time and weather conditions may change the snow surface. Then the surface will help reflect sound waves. Sounds may seem clearer and travel farther under these circumstances. […]
What year will the sun explode?
What year will the sun explode? In about 5.5 billion years the Sun will run out of hydrogen and begin expanding as it burns helium. It will swap from being a yellow giant to a red giant, expanding beyond the orbit of Mars and vaporizing Earth—including the atoms that make-up you. Is Sun getting weaker? […]
What is the degree of freedom at critical point?
What is the degree of freedom at critical point? In the critical point the difference of density between the liquid phase and the vapour phase is so small the are indistinguishable, hence considered as single phase. So according the gibbs phase rule (. F=C – P +2) the degree of freedom should be 2. What […]
