Answer:
a) h=10.701m
b) No. On this case a liquid like wine is not good as the mercury, because the wine is composed of water, alcohol and other elements, but specially the alcohol evaporates much easier than the mercury, and that will cause malfunction in the vacuum of the baroemter used for the experiment.
Explanation:
The Torricelli's experiment "was invented by the Italian scientist Evangelista Torricelli and the most important purpose of this experiment was to prove that the source of vacuum comes from atmospheric pressure"
Pressure is defined as "the force that is applied on any object in the direction perpendicular to the surface of the object in the unit area is known as the pressure. There are various types of pressure".
Part a
We have the density for the red Bordeaux wine given 
, the atmospheric pressure on the Toriccelli's barometer is given by:
Solving for the height of wine in the column we have this:
And replacing we have:
So the height of the red Bordeaux wine would be h=10.701m. A very high value on this case if we compare with the usual values for this variable.
Part b
No. On this case a liquid like wine is not good as the mercury, because the wine is composed of water, alcohol and other elements, but specially the alcohol evaporates much easier than the mercury, and that will cause malfunction in the vacuum of the baroemter used for the experiment.
<span>The lifting force generated by fluids on immersed objects is known as <span>"Buoyant Force".

So, in short, fill "Buoyant Force" in the blank!
Hope this helps!

Complete question is;
An ideal pendulum is often discussed when studying simple harmonic motion.
What are the conditions needed for an ideal pendulum? Check all that apply.
1) Gravitational force acts to pull the pendulum’s mass down.
2) The mass of the rod of the pendulum is evenly distributed along the rod.
3) The pivot on which the pendulum swings is frictionless.
4) The pendulum swings through its equilibrium position as a result of inertia.
5) Tension acts downward on the pendulum’s mass
Answer:
Conditions 2,3 & 4 are the ones that apply
Explanation:
The conditions required for an ideal pendulum are;
- The mass of the rod of the pendulum has to be evenly distributed along the rod.
- Ensure that the pivot on which the pendulum is swinging is frictionless
-The pendulum has to swing through it's equilibrium position as a result of inertia.
Thus,the correct options are 2, 3, 4.
This should be the answer
