Acube with 15-cm-long sides is sitting on the bottom of an aquarium in which the water is one meter deep. (round your answers to the nearest whole number. use 9.8 m/s2 for the acceleration due to gravity. recall that the weight density of water is 1000 kg/m3.) (a) estimate the hydrostatic force on the top of the cube. n (b) estimate the hydrostatic force on one of the sides of the cube.

0.204 KN

Step-by-step explanation:

Height above cube h= (100-15)/100 =  0.85 m

a) force on the top of the cube = ρgh×area

= 1000×9.81×0.85 = 8330 N/m^2

= 833 KN/m^2*0.15^2= 0.187 KN

b) Force on one side of the cube

on top = 8.33 KN/m^2

at bottom ρgh

= 1000×9.8×100/100

=9800 N/m^2

Net Force =  area of the diagram

= 8.33×(15/100)^2 + 1/2(9.8-8.33)×(15/100)^2

= 0.204 KN

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent
