You are to design a continuous-time, second-order, lowpass filter that has the following specifications.
Design a circuit that provides a relationship between output voltage Vo and input voltage Vs such that Vo=12*Vs -10. Two opamps, a 6-V battery, and several resistors are available.
The manufacturer of a 9V dry-cell flash light battery says that the battery will deliver 20mA for 80 continuous hours. During that time the voltage will drop from 9V to 6V.Assuming the drop in voltage is linear with time.
A dielectric sphere has radius r = 2 and the material inside the sphere has dielectric constant er2 = 4. THe region outside the sphere where r > 2 is free space and the electric field there is E1=(16r+2+8\phi). Find electric field E2 inside the sp..
Box 1 contains 5 red, 6 white, and 9 blue balls. Box 2 contains 7 red, 8 white, and 4 blue balls. A ball is withdrawn at random from Box 1 and placed in Box 2. Then, a ball is taken at random from Box 2.
