How long should you idle a car to charge the battery? If you find any of these cars start easily (the starter spins quickly), battery status is likely quite good, and a short drive or idling for 10 to 15 minutes may be adequate to keep the battery full, if done once every two weeks. […]
What is the difference between IR and FTIR?
What is the difference between IR and FTIR? FTIR spectrometers have several prominent advantages: (1) The signal-to-noise ratio of spectrum is significantly higher than the previous generation infrared spectrometers. (2) The accuracy of wavenumber is high. Due to these advantages, FTIR Spectrometers have replaced dispersive IR spectrometers. What is the principle of IR spectroscopy? IR […]
What is the orange soil on the moon?
What is the orange soil on the moon? Abstract. THE discovery of an orange-coloured soil on the Moon by the Apollo 17 astronauts last December led to much excitement and speculation. Dr Jack Schmitt, the geologist on the mission, realized that such yellow to orange coloration in rocks on Earth is usually due to hydrated […]

Is forced hot air unhealthy?
Is forced hot air unhealthy? The biggest downside of using a forced air heating system is that it leaves you vulnerable to inefficiency stemming from ductwork problems. If your ductwork is well-designed, expertly installed, and kept in prime condition, then you’ll be able to heat your home quite efficiently. Is forced air heating cheaper? Other […]
What are the 3 major layers of the geosphere?
What are the 3 major layers of the geosphere? The Earth’s geosphere is divided into three chemical sections: The crust, composed almost entirely of light elements, like silicon. The mantle, which is 68% of the Earth’s mass. The core, the innermost layer; it is composed of very dense elements, such as nickel and iron. What […]
What is induction conduction and friction when charging an object?
What is induction conduction and friction when charging an object? Friction – the transfer of electrons from one object to the other. Conduction – by having two objects TOUCH each other and transfer electrons from one object to the next. Induction – By inducing electrons to move from one object to the other. What is […]
Do archeologists lick bones?
Do archeologists lick bones? Archaeologists sometimes used to lick artifacts they excavated in the field to determine if they were bone or not. That said, most modern archaeologists do not do either of these things because spit can contaminate artifacts, ruining archaeological information that could be picked up by things like residue analysis. Do people […]
What part of the retina is responsible for the sharpest vision?
What part of the retina is responsible for the sharpest vision? In the middle of the retina is a small dimple called the fovea or fovea centralis. It is the center of the eye’s sharpest vision and the location of most color perception. What part of the retina is most sensitive to light? fovea centralis […]
