Give 10 expression for derived quantities |
|
Answer» Explanation: SI base units The SI is founded on seven SI base units for seven base quantities assumed to be mutually independent, as GIVEN in Table 1. Table 1. SI base units SI base unit Base quantity Name Symbol length meter m mass kilogram kg time second s electric current ampere A thermodynamic temperature kelvin K amount of substance mole mol luminous intensity candela cd For detailed INFORMATION on the SI base units, SEE Definitions of the SI base units and their Historical context. SI derived units Other quantities, called derived quantities, are defined in terms of the seven base quantities via a system of quantity equations. The SI derived units for these derived quantities are obtained from these equations and the seven SI base units. Examples of such SI derived units are given in Table 2, where it should be noted that the symbol 1 for quantities of dimension 1 such as mass fraction is generally omitted. Table 2. Examples of SI derived units SI derived unit Derived quantity Name Symbol area SQUARE meter m2 volume cubic meter m3 speed, velocity meter per second m/s acceleration meter per second squared m/s2 wave number reciprocal meter m-1 mass density kilogram per cubic meter kg/m3 specific volume cubic meter per kilogram m3/kg current density ampere per square meter A/m2 magnetic field strength ampere per meter A/m amount-of-substance concentration mole per cubic meter mol/m3 luminance candela per square meter cd/m2 mass fraction kilogram per kilogram, which may be REPRESENTED by the number 1 kg/kg = 1

What is the normal temperature of human body on celcius scale? |
|
Answer» The average NORMAL body temperature is generally accepted as 98.6°F (37°C). Some STUDIES have shown that the "normal" body temperature can have a wide RANGE, from 97°F (36.1°C) to 99°F (37.2°C). A temperature over 100.4°F (38°C) most often means you have a fever CAUSED by an infection or illness. |

Answer» I hope it will be HELP you pls mark me as Brainlist answer When does caution become PARANOIA? We ASK experts what the right way to clean groceries was, whether bought or delivered
Weekly grocery runs are now characterised by masks, alcohol-based sanitiser bottles, and a pair of gloves, as people around the globe try to adhere to the NORMS of physical distancing while shopping for essentials. What do you do with groceries thereafter? On social media, we have seen some put veggies in the dishwasher; some scrub them down with alcohol-based wipes; and some soak them in potassium permanganate. But when does caution become paranoia? We asked experts what the right way to clean groceries was, whether we were bringing them in or a delivery was. First though, “Remember that it is a respiratory virus we are dealing with: that it has to be inhaled to cause infection; and not ingested. So, that is what we need to safeguard against,” says Dr Ravi Santosham, Chennai-based pulmonologist. However, maintaining this level of cleanliness and hygiene can reduce the possibility of contracting any aerosol or droplet-related infections, such as tuberculosis. |

An inventor claims to have developed a heat engine working between temperature 27°c and 227°c having efficiency of 45% is the claim valid? Prove |
|
Answer» Answer: If this engine is only thermal, such an EFFICIENCY is theoretical impossible. The thermal cycle can’t have a higher efficiency than the CARNOT cycle operating between the same temperatures. The latter has an efficiency of NEARLY 40%, moreover theoretical. A REAL Carnot engine moreover would have quite less efficiency. The alleged engine can’t have an efficiency of 45%. |

A modern F1 car accelerates from 0 to 62 miles per hour in 2.50 seconds what is the angular acceleration of it's 170mm radius wheels |
|
Answer» Answer: The highest speed I can remember off the top of my head was set by WILLIAMS last year at the Baku GP. They managed to reach 378kph (234mph). F1 cars are a compromise between top speed and downforce, most of the tracks FAVOUR HIGHER downforce over a higher top speed. So it would be possible to EXCEED these speeds if the car was set up for it (low DRAG wings etc.). |
