Answer:
The permittivity measures the obstruction produces by the material in the formation of the electric field, whereas permeability is the ability of the material to allow magnetic lines to conduct through it. The free space of the permittivity is 8.85 F/m, whereas that of the permeability is 1.26 H/m.
Explanation:
Average age in a population. Suppose the 100-vector x represents the distribution of ages in some population of people, with xi being the number of i−1 year olds, for i = 1, . . . , 100. (You can assume that x 6= 0, and that there is no one in the population over age 99.) Find expressions, using vector notation, for the following quantities. (a) The total number of people in the population. (b) The total number of people in the population age 65 and over. (c) The average age of the population. (You can use ordinary division of numbers in your expression.)
Which is a common refrigerant for domestic air conditioners?
Answer:
Explanation:
The most common HFC used in air conditioners is R-410A. This refrigerant is better than R-22 in terms of “Ozone Depletion” potential and energy efficiency, but it still causes global warming. A few more HFCs that are commonly used are: R-32 in Air Conditioners and R-134A in refrigerators.
