What liquid is used in lava lamps? The whirling globs we remember are made mainly of paraffin wax, with compounds like carbon tetrachloride added to increase its density. The liquid the wax floats in can be water or mineral oil, with dyes and sparkles added for whimsy. Is it real lava in lava lamps? The […]
Do wider tires affect gas mileage?
Do wider tires affect gas mileage? For example, larger tires decrease your fuel economy because they are heavier, while smaller tires increase fuel efficiency. Bigger tires also have a higher rolling resistance than smaller tires which means they require more resistance and effort to get them rolling. What are good tires for rain? The 10 […]
What is the formula for frequency of light?
What is the formula for frequency of light? Divide the speed of light, ~300,000,000 m/s, by the wavelength in m. This gives you the wave’s frequency. What is the frequency of red light? around 430 terahertz Does blue or red light have a higher frequency? Blue light has shorter waves, with wavelengths between about 450 […]
Is energy transferred when two atoms collide?
Is energy transferred when two atoms collide? These atoms frequently collide and transfer energy between one another. Therefore, when two atoms collide and start to oscillate, some energy may be transferred to other particles by collisions. If this happens, a stable interaction can form between the two particles; they will “stick” together. At what point […]
What is the difference between being charged and being indicted?
What is the difference between being charged and being indicted? A charge is brought against someone by a prosecutor. But in an indictment, a grand jury brings the charges against the defendant. All indictments are charges, but not all charges are indictments. How do you know if you’re being indicted? Basically, if federal agents came […]

For 345 kV Power lines you have to maintain 250 feet distance. Is it dangerous to live near power transformers? Most scientists […]
Why do water bottles have an air hole?
What is the acceleration on the moon?
What is the acceleration on the moon? Bulk parameters Moon Earth Mean density (kg/m3) 3344 5514 Surface gravity (m/s2) 1.62 9.80 Surface acceleration (m/s2) 1.62 9.78 Escape velocity (km/s) 2.38 11.2 Does the Moon experience centripetal acceleration? The centripetal acceleration of the moon is v2/r. Details of the calculation: (a) The distance the moon travels […]
Is viscosity dependent on temperature?
Is viscosity dependent on temperature? According to the kinetic theory of gases, viscosity should be proportional to the square root of the absolute temperature, in practice, it increases more rapidly. With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same. Does salt increase surface tension? Yes, adding […]
