A -802.4 uC charge is embedded in the ceiling. Hovering in the air below this charge by 0.5 m is another 3.1 kg charge with an unknown amount of positive charge on it. Attached to the bottom of this positive charge is a string that is under 12 N of tension. What is the amount charge on the positive charge? (Enter your answer in micro-Coulombs)

A charge of +1.8 micro-coulombs lies on a horizontal surface. It has a mass of 2 kg and the coefficient of static friction between it and the surface is 1.69. Another charge of -3.9 micro- coulombs lies on the horizontal surface 10 cm to the right of the charge. A third charge which is negative is located 14 cm above the positive charge on the surface. What is the smallest magnitude this charge needs to be in order for the...

4. Travelling Waves and Their Characteristics A rope wave travels in the positive x -direction. You are also told that the speed of the wave is 1000 cm/s, its frequency is 200 Hz, and that the wave is subject to the following initial conditions: at x 0 and t = 0: y =-1 cm, and, at x = 0 and t : ar = +20 cm/s (this is the velocity of the point on the rope at horizontal...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
