What is the ideal atmospheric pressure?
What is the ideal atmospheric pressure? Standard sea-level pressure, by definition, equals 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch, 1,013.25 × 103 dynes per square centimetre, 1,013.25 millibars, one standard atmosphere, or 101.325 kilopascals. Why don’t you feel the pressure exerted by the atmosphere? The reason we can’t feel it is […]
What is the most precise atomic clock?
What is the most precise atomic clock? An all-optical atomic clock, recently demonstrated by researchers at the US National Institute of Standards and Technology (NIST; Gaithersburg, MD), produces about 1 quadrillion “ticks” per second and promises to be as much as 1000 times more accurate than the world’s current standard in time measurement-cesium-based … Which […]
How are tides affected by the moon?
How are tides affected by the moon? High and low tides are caused by the moon. The moon’s gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high […]
How do you simplify two complex numbers?
How do you simplify two complex numbers? Step 1: Distribute (or FOIL) using only the first two complex numbers. Step 2: Simplify the powers of i, specifically remember that i2 = –1. Step 3: Combine like terms, that is, combine real numbers with real numbers and imaginary numbers with imaginary numbers. Step 4: Distribute (or […]
What does the elevator do on a plane?
What does the elevator do on a plane? An elevator is a primary flight control surface that controls movement about the lateral axis of an aircraft. This movement is referred to as “pitch”. Most aircraft have two elevators, one of which is mounted on the trailing edge of each half of the horizontal stabilizer. What […]
What is an example of forced convection?
What is an example of forced convection? Forced convection: When external sources such as fans and pumps are used for creating induced convection, it is known as forced convection. Examples of forced convection are using water heaters or geysers for instant heating of water and using a fan on a hot summer day. What is […]
What are proteins the building blocks for?
What are proteins the building blocks for? protein: building blocks When we eat protein, our body breaks these large molecules down into smaller units called amino acids. These building blocks are used for many important functions in the body, including growth and repair of muscle, connective tissue and skin. What are the major functions of […]
How can a source be both primary and secondary?
How can a source be both primary and secondary? Primary and secondary categories are often not fixed and depend on the study or research you are undertaking. For example, newspaper editorial/opinion pieces can be both primary and secondary. If exploring how an event affected people at a certain time, this type of source would be […]
Can I make hydrochloric acid?
Can I make hydrochloric acid? Production. Hydrochloric acid is usually prepared industrially by dissolving hydrogen chloride in water. Hydrogen chloride can be generated in many ways, and thus several precursors to hydrochloric acid exist. Where do you get hydrochloric acid? Hydrochloric acid is the water-based, or aqueous, solution of hydrogen chloride gas. It is also […]
