(a) 5.66 m/s
The flow rate of the water in the pipe is given by

where
Q is the flow rate
A is the cross-sectional area of the pipe
v is the speed of the water
Here we have

the radius of the pipe is
r = 0.260 m
So the cross-sectional area is

So we can re-arrange the equation to find the speed of the water:

(b) 0.326 m
The flow rate along the pipe is conserved, so we can write:

where we have

and where
is the cross-sectional area of the pipe at the second point.
Solving for A2,

And finally we can find the radius of the pipe at that point:

I think the answer will be A
A. it is <span>located at a distance of 2.6 million light years from earth</span>
Our team is having a really hard time trying to decode the gibberish
in the question, but they do seem to be picking up a message that
you're in an exam. If that's true, then thank you for taking some of
your precious exam time to greet your many friends on Brainly.
Now turn off your phone and drag your attention back to the exam.
Do you mean when objects move as a direct result of the passing wave?
Waves have energy and constitute a force, just like wind. Therefore that
force is able to move objects in its path.
