Derive the equation for = (). (Assume that the transistor in active region.) (b) Find the voltage range that keeps the transistor in active region. Assume = 150, cc = 1 , = 30 . (c) Draw the small signal model and find the small signal voltage gain in terms of , cc, and . (d) Find the expressions for input and output resistances.

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
