The huka falls on the waikato river is one of new zealand's most visited natural tourist attractions. on average the river has a flow rate of about 300,000 l/s. at the gorge, the river narrows to 18 m wide and averages 22 m deep.(a) what is the average speed (in m/s) of the river in the /s.(b) what is the average speed (in m/s) of the water in the river downstream of the falls when it widens to 63 m and its depth increases to an average of 42 /s.

How to tell if a molecule is polar or nonpolar with electronegativity

Under the action of a constant force an object accelerates at 7.8 m/s2. what will the acceleration be if (a) the force is halved? (b) the object's mass is halved? (c) the force and the object's mass are both halved? (d) the force is halved and the object's mass is doubled?

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
