2. A silicon BJT is connected as shown in Figure 2. Assume that the absolute value of the base-emitter forward bias is 0.8 V, the current transfer ratio ß is 50, and the collector cut off
current ICEO is approximately zero. The power supply Vcc=15V. (20%)
(a) Compute the base current Ib and the collector current Ib. (10%)
(b) Compute the collector-emitter voltage VCE. (2%)
(c) What is the collector saturation current? (3%)
(d) Specify Rb1 to establish VCE=5V. (5%)

Simon is writing a story about an astronaut whose spacecraft has been boarded by space pirates. the astronaut has her lucky penny in her hand behind her back as the space pirates break into the control room. she has just locked the controls so that the ship is accelerating in the direction of the control room’s ceiling. simon wants the astronaut to use the penny to hit a button on the control panel to turn off the lights and escape. the button is located a short distance behind and below the astronaut’s hands. how should simon use the theory of relativity to describe what the astronaut must do in order to hit the button?

1. when conducting a test on what kind of music increases the growth of plants, all of the following would fail to meet to fair test standard except (1 point) using different kinds of plants. giving some plants more water than others. exposing the plants to different types of music. using nutrient-rich soil for one and lesser soil for others. 2. engineering uses scientific thinking to solve real-world problems. (1 point) true false 3. what does it mean to test a hypothesis? (1 point) pass a quiz on other scientists’ results analyze only the results from scientific sources not make assumptions about how an experiment will turn out see if the results of an experiment are what the scientist predicted
