Answer:
Hydrostatic Force = 35.28KN
Step-by-step explanation:
To solve this question, let's consider integrating the hydrostatic force from the top of the triangle to the bottom.
Formula for a thin horizontal slice of the triangle the force is;
δF=ρgxwδx
Where w is width of triangle; ρ is density of water and g is acceleration due to gravity
At depth x, the width of the triangle is w=2/3x.
Thus, F = (3,0)∫)ρgxwδx
=(2/3)ρg[(3,0)∫)x²δx]
= integrating, we have;
F = (2/3)ρg[(3³/3) - (0³/3)]
F = (2/5)ρg [27/3] = (2/5)(1000)(9.8)(9) = 35280 N = 35.28 KN
Answer:
rate = 316800 feet miles per hour
unit = feet per hour
Step-by-step explanation:
swimming rate of fish = 60 miles per hour
1 mile = 5280 feet
60 miles = 60*5280 feet = 316800 feet
swimming rate of fish = 60 miles per hour
substituting 60 miles with with its equivalent in feet we have
swimming rate of fish = 316800 feet miles per hour
answer
rate = 316800 feet miles per hour
unit = feet per hour
