Does a light without bulb use electricity? If a light switch is on to a busted bulb, does it still use electricity? No, not unless you see light coming from it. A bulb that is burned out usually has it’s filament destroyed, therefore it is an open circuit and uses no power. What happens if […]

How long was the chemical evolution? a billion years What was the first life form on Earth? The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old. The signals consisted of a type of carbon molecule that is produced by living […]

Which moon has lowest density? Moon of Saturn Moon Are there many earths in universe? On November 4, 2013, astronomers reported, based on Kepler space mission data, that there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of Sun-like stars and red dwarf stars within the Milky Way Galaxy. […]

What 4 types of evidence do we use to construct the tree? Evidence for building trees DNA and RNA sequences (as well as other molecular traits like the amino acid sequences of proteins). Morphology (i.e., structure and form). What is a branching tree diagram? A branching tree diagram is a set of groups within groups, […]

Can you replace argon gas in Windows? Yes. If you send out a window professional for an inspection, he or she can gauge the current level of argon gas in your double-pane windows. If a substantial amount has been lost then there is a method to replace the gas between the panes of glass. However, […]

How many GB is a 1000 photos? 2 Gb How do I convert my digital storage? To convert larger units to smaller units (i.e. take a number of gigabytes and convert it down in to megabytes, kilobytes, or bytes) you simply multiply the original number by 1,024 for each unit size along the way to […]

What causes dispersion? Dispersion occurs due to the different degrees of refraction experienced by different colours of light. Light of different colours may travel with the same speed in a vacuum, but they travel at different speeds in some refracting medium. The speed of violet light is relatively lower than that of red light. Why […]
