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.
Answer:
Explanation:
From the question we are told that
The number of slits per cm is k =
The order of the maxima is n = 1
The wavelength are
The spacing between the slit is mathematically represented as
=>
=>
Generally the condition for constructive interference is
