What are the 8 most common minerals? You should learn the symbols for the eight most abundant elements in the Earth’s crust (Oxygen (O), Silicon (Si), Aluminum (Al), Calcium (Ca), Iron (Fe), Magnesium (Mg), Sodium (Na), and Potassium (K) . What is Earth’s most common element? Oxygen What is the least abundant element in the […]
What property do hypotheses and theories have in common?
What property do hypotheses and theories have in common? Answer and Explanation: One major factor that a scientific hypothesis, theory, and law have in common is that they are all based on observations. Why do scientists use variables? In science, a variable is any item, factor, or condition that can be controlled or changed. Using […]
Is it OK to use WD40 on bike chain?
What color lenses are good for night driving?
What color lenses are good for night driving? Night driving glasses are available in many shades of yellow and amber. The darkest lenses filter out the most glare but also, the largest amount of light, making it hard to see in dim or dark conditions. Some wearers of night driving glasses report that they’re better […]
Is salinity higher in deep water?
Is salinity higher in deep water? Typically, the salinity decreases from the surface ocean to deep waters is very small, from about 36 g/L (ppt) at the surface to 35 g/L (ppt) in the deep water, thus there is a very small density decrease with depth given a constant temperature. The salinity of seawater also […]
How can I improve the air quality in my home?
Can electricity be transmitted without wires?
Can electricity be transmitted without wires? Wireless power transfer (WPT), wireless power transmission, wireless energy transmission (WET), or electromagnetic power transfer is the transmission of electrical energy without wires as a physical link. These techniques can transport energy longer distances but must be aimed at the receiver. What happens if air is good conductor of […]
Which type of heating system is best?
Which type of heating system is best? Geothermal systems What is the most efficient heating system for a house? Active solar heating may be the most efficient option for heating your home. Electric resistance heating can be expensive to operate, but may be appropriate if you heat a room infrequently or if it would be […]
What force allows us to walk forward?
What force allows us to walk forward? friction What happens if we break the laws of physics? If you break the laws of Physics, you’ll end up in Physics Jail. Physics is relative. No human can defy its “laws” just as no quantum particle does either. Can you change the laws of physics? The physical […]
What is the temperature of the South Equatorial Current?
What is the temperature of the South Equatorial Current? The average temperature of the South Equatorial Current is about 26°-28°C near the surface and 22°-24°C at 100 m depth (Mayer and al., 1998). The annual cycle of temperature is relatively stable between March and September, the two seasonal extremes, with a variability of about 4°C. […]
