Question

Two people, that are 10.4 m apart, stretch a rope (2.31 kg) with a tension of 74.4 N. If one person sends a pulse through the

Answer 1

Answer #1

The velocity of a wave on a rope is given by,

m/L

T is the tension, m is the mass of the rope and L is the length of the rope. Substituting values we get,

74.4 U = V 2.31/10.4 = 18.3m/s

So time taken for a disturbance to travel from one end to another end is,

distance 10.4 ta > = = 0.568 S speed 18.3

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...
