Explanation:
The diagram for this question is shown on the first uploaded image
At Equilibrium the summation of the of force on the vertical axis is zero
i.e
=>
is the is the speed of water at the nozzle which can be mathematically evaluated as
substituting for R and
for
is the is the speed of water at the pipe which can be mathematically evaluated as
substituting for R and
for
is he density of water with value
Substituting values into the equation above
At Equilibrium the summation of the of force on the horizontal axis is zero
i.e
=>
Since The speed at both A and B nozzle are the same then remains the same
Substituting values
=>
Hence the force acting on the flange bolts required to hold the nozzle in place is
Answer:
10.2 m
Explanation:
The position of the dark fringes (destructive interference) formed on a distant screen in the interference pattern produced by diffraction from a single slit are given by the formula:
where
y is the position of the m-th minimum
m is the order of the minimum
D is the distance of the screen from the slit
d is the width of the slit
is the wavelength of the light used
In this problem we have:
is the wavelength of the light
is the width of the slit
m = 13 is the order of the minimum
is the distance of the 13th dark fringe from the central maximum
Solving for D, we find the distance of the screen from the slit:
Answer:
270 mi/h
Explanation:
Given that,
To the south,
v₁ = 300 mi/h, t₁ = 2 h
We can find distance, d₁
To the north,
v₂ = 250 mi/h, d₂ = 750 miles
We can find time, t₂
Now,
Average speed = total distance/total time
Hence, the average speed for the trip is 270 mi/h.
