Hi, I've been given a situational problem where I have to find the total amount of contaminants in a river once outflow of contaminant has been introduced. So basically: River flow (80 000m^3 [Cu]=0ppm) _ -->Doesn't reach plant (72 000 m^3 [Cu]=0ppm)...

A duck has a mass of 2.20 kg. As the duck paddles, a force of 0.110 N acts on it in a direction due east. In addition, the current of the water exerts a force of 0.180 N in a direction of 54.0 ° south of east. When these forces begin to act, the velocity of the duck is 0.100 m/s in a direction...

A block whose weight is 56.5 N rests on a horizontal table. A horizontal force of 45.2 N is applied to the block. The coefficients of static and kinetic friction are 0.687 and 0.479, respectively. Will the block move under the influence of the force, and, if so, what will be the block's...
