Your pendulum does a complete swing in 1.9 seconds. You want to SLOW IT DOWN so it takes 2.0 seconds.
Longer pendulums swing slower.
You need to <em>make your pendulum slightly longer</em>.
If your pendulum is hanging by a thread or a thin string, then its speed doesn't depend at all on the weight at the bottom. You can add weight or cut some off, and it won't change the speed a bit.
Answer:
The speed in the smaller section is 
Explanation:
Assuming all the parts of the pipe are at the same height, we can use continuity equation for incompressible fluids:
(1)
With Q the flux of water that is
with A the cross section area and v the velocity, so by (1):
subscript 2 is for the smaller section and 1 for the larger section, solving for
:
(2)
The cross section areas of the pipe are:


but the problem states that the diameter decreases 86% so
, using this on (2):


Answer:
b should be the answer
Explanation:
its talking about the weather and not about the climate
Answer:
It depends on the environment you're in but I'd go with warm
