A cube with 15-cm-long sides is sitting on the bottom of an aquarium in which the water is one meter deep. (Round your answers t

Ghella [55]

Answer:

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

Question 14. Select the correct answer. If f(x)=x^2/x+3, find f(x+h)

vekshin1

Answer:

$f(x+h)=\frac{x^2+2h+h^2}{x+h+3}$

Step-by-step explanation:

we have

$f(x)=\frac{x^2}{x+3}$

To find out f(x+h), substitute the variable x by the variable (x+h) in the function f(x)

so

$f(x+h)=\frac{(x+h)^2}{(x+h)+3}$

$f(x+h)=\frac{x^2+2h+h^2}{x+h+3}$
