Answer:58.28 N
Explanation:
Given data



Now velocity of jet at height of 2m




equating them
W=
W=
W=58.28 N
Answer:

Explanation:
Given that
R=8 ft
Width= 10 ft
We know that hydro statics force given as
F=ρ g A X
ρ is the density of fluid
A projected area on vertical plane
X is distance of center mass of projected plane from free surface of water.
Here
X=8/2 ⇒X=4 ft
A=8 x 10=80 
So now putting the values
F=ρ g A X
F=62.4(32.14)(80)(4)

Answer:
f(x)=23x−2
Explanation:
still trying to figure that out
You need to explain it more simple as everyone is clueless
