A washing machine's two spin cycles are 305 rev/min and 450 rev/min. The diameter of the drum is 0.43 m. (a) What is the ratio of the centripetal accelerations for the fast and slow spin cycles? afast/aslow = Incorrect: Your answer is incorrect. (b) What is the ratio of the linear velocity of an object at the surface of the drum for the fast and slow spin cycles? vfast/vslow =

A washing machine drum 72.0 cm in diameter starts from rest and achieves 1200.0 rev/min in 20.0 s. Assume the acceleration of the drum is constant. 1) Calculate the magnitude of the net acceleration of a point on the drum after 1.00 s has elapsed. (Express your answer to three significant figures.) 2) Specify the direction of the net acceleration of a point on the drum after 1.00 s has elapsed. (Express your answer to two significant figures.)

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...
