Question 1. The arrangement of charges in figure 4-9 (a) is called an electrostatic dipole.
If the charges are + 1.0 LiC and - 1.0 12C respectively, and are 1 mm apart
(a) show that the total force midway between the charges is twice the force due to one charge.
(b) calculate the force due to the negative charge -Q on a test charge of +1.00 coulombs at a point 1 mm to the right of -Q
(c) calculate the force at the same point as (b)on the test charge of +1.00 coulombs due to the positive charge +Q
(d) calculate the resultant force, and show the magnitude and direction of the two forces and their resultant on a sketch
What are the design implications for the location and positioning of solar cells? Explain why the use of solar cells might be more appropriate in some regions of the country.
Create menus and sub menus to allow the user to select the functions they need. 1. Allow the user to enter 20 inventory items into the program. Use string arrays to track the name of the of the product and use double arrays to store the price of e..
calculate the resistor's resistance. If the bandwidth were cut to 25 kHz, determine the expected output meter reading.
How much charge is inside this 34.0-cm diameter spherical surface
Can the same circuit analysis techniques used for resistive circuits with DC sources be used when the sources are sinusoidal Why
Consider the problem of using a low voltage system to power a small cabin. Suppose a 12-V system powers a pair of 100-W light bulbs (wired in parallel). A) What would be the filament resistance of a bulb designed to use 100 W when it receives 12 V

A 240-V, 900-rpm, dc series motor takes 25 A at full load. The armature and field-winding resistances are 0.2 ohm and 0.3 ohm, respectively. The rotational loss is 300 W. Calculate (a) the power developed, (b) the power output, (c) the available t..
Discuss the effects of signal attenuation on the noise figure. Why is it important to minimize losses in the input of the amplifier
The amount of heat Q needed to turn a mass, m, of room temperature ( T_1) water into steam at 100 Celcius. ( T_2) can be found using the specific heat, c, of water and the heat of vaporization, H_v, of water at 1 atmosphere of pressure.
The variables are provided as high (1) and low (0) levels for digital control. An alarm should be initiated whenever any of the following occur: a. Speed is low; both weight and loading rate are high.
1) Determine the transfer of second-order highpass filter with a cutoff frequency of 900 Hz and passband gain of 1 using a butterworth type. 2) Design a filter for your transfer function from question.1 using the sallen-Key topology.
