Calculate the frequency of a ujt relaxation oscillator when re is 10k ohms and ce is 0.1uf 2. suppose a square wave signal has a 65 percent duty cycle and an on-state voltage of 40 volts dc. what is the average dc voltage? if the full temperature range of an on-off heating system is from 30 to 100 degrees and the differential gap is 5 degrees, what is the deadband? if the gain of a proportional mode system is set to high, the proportional band is (narrow, wide), the response is the derivative mode provides a boost to the system if the magnitude of the error signal is 3. 4. (fast, slow), and the system is unstable. 5. if the output of a proportional mode control system oscillates, the system gain is set too 6. (high, low), its proportional band is (narrow, wide), and the response time is (fast, slow).

Asystematic approach to problem solving is called a (an)

Which of the following situations is impossible? a) an object has velocity directed east and acceleration directed east. b) an object has zero velocity but non-zero acceleration. c) an object has constant non-zero velocity and changing acceleration. d) an object has velocity directed east and acceleration directed west. e) an object has constant non-zero acceleration and changing velocity.

In the nineteenth century, gregor mendel first determined some basic rules of genetics that have been observed throughout all types of life. no observations have disproved these basic rules of genetics. charles darwin developed the idea of biological evolution around the same time, but he was unaware of mendel’s discoveries in genetics. over a century later, darwin’s idea of evolution was modified in order to incorporate mendel’s rules of genetics along with the other evidence that darwin had used. what is most likely the relationship between mendel’s rules of genetics and darwin’s idea of biological evolution? a.)mendel’s genetics states laws that are now part of the theory of biological evolution. b.)biological evolution states laws that are part of mendel’s theory of genetics. c.)mendel’s genetics replaced darwin’s entire concept of biological evolution. d.)biological evolution is a law that explains why all genetics exist.
