Answer: Wet barometer - The tool works by measuring atmospheric pressure to predict incoming weather. Since the glass is only filled halfway with water, the other half is exposed to the atmosphere. When the outdoor atmospheric pressure rises, the pressure in the glass decreases, and causes the water to move down the spout.
Dry barometer - A Torricellian barometer (sometimes called a mercury barometer) is an inverted (upside-down) glass tube standing in a bath of mercury. Air pressure pushes down on the surface of the mercury, making some rise up the tube. The greater the air pressure, the higher the mercury rises.
I hope this helps!
I think answer should be 15 I think you should google it on the internet
Answer: HOPE THIS HELPED YOU! :D ;P
Elastic potential energy = force x distance of displacement.
Explanation:
Answer:

Becuase 
So then we can conclude that:

And that makes sense since the force
needs to accelerate the two masses and
just need to accelerate
.
So the best option for this case would be:
a. T1 > T2
See explanation below.
Explanation:
For this case we consider the system as shown on the figure attached.
Since the system is connected the acceleration for both masses are equal, that is 
From the second Law of Newthon we have that the force applied for the mass
is
and we know that the force acting on the x axis for the mass 2 is
so then we have that 
Now when we consider the system of
as a whole mass, this system have the same acceleration
and on this case we will see that the only force acting on the entire system would be
and then by the second law of Newton we have that:

And then if we compare
and
we see that :

Becuase 
So then we can conclude that:

And that makes sense since the force
needs to accelerate the two masses and
just need to accelerate
.
So the best option for this case would be:
a. T1 > T2
