Just as a resistor has a resistance, a capacitor has a reactance. The reactance, xc, can be modeled as Xc= 1/wC, where w is the angular freuqency of the circuit. For a purely capactive circuit, Z=XcQuesitons:1) How are frequency (f) and angular frequency (w) related? provide the numerical relationship in your answer2) If the angular frequency of the circuit is very large, is the circuit changing rapidly or slowly?3) Given a capacitor of fixed capacitance C, in a circuit with a very large angular frequency, is Xc large or small?4) Given a capaacitor of fixed capacitance C, in a circuit with a very large angular frequency, does current flow quickly or slowly in the circuit?
Which pattern will reach 8 first ? a) 26, 23, 20, 17, 14 b) 29, 24, 19, 14, 9c) 15, 14, 13, 12, 11
is it true that the The biological levels of organization allow different types of cells to work together to form fully functioning multicellular organisms. Cells working together make tissues, tissues working together make organs, organs working together make organ systems, and all of the organism systems working together make fully functioning organs. This organization allows all of the specialized cells, tissues, organs, and organ systems to carry out the many functions necessary for a multicellular organism to grow and survive, this is referred to as the division of labour and means you can walk, talk, think, breathe, digest, and do many other things at the same time.
