On a day in which the local atmospheric pressure is 99.5 kPa, answer each of the following: (a) Calculate the column height of mercury in a mercury barometer in units of meters, feet, and inches. (b) Francis is concerned about mercury poisoning, so he builds a water barometer to replace the mercury barometer. Calculate the column height of water in the water barometer in units of meters, feet, and inches. (c) Explain why a water barometer is not very practical. (d) Ignoring the practicality issue, which of the two (mercury or water) would be more precise
Answer:
C . . . . . . . . . . . . . . . . . . . . . .
(a) The column height of mercury in a mercury barometer is 7.32 meters, or 24.0 feet, or 95.2 inches.
What is the column height?(b) The column height of water in a water barometer is 995 meters, or 3268 feet, or 33.9 feet.
(c) A water barometer is not very practical because it would need to be very tall to measure atmospheric pressure.
(d) Ignoring the practicality issue, a mercury barometer would be more precise because mercury is denser than water.
Mercury barometer: 7.32 m, 24 ft, 95.2 in
Water barometer: 995 m, 3268 ft, 33.9 ft
Water barometer not practical because it would be too tall
Mercury barometer more precise because mercury is denser

A voltage drop test is being performed on the output wire of the alternator to the battery positive post. Technician A says that the voltage drop should be more than 0.5 volts. Technician B says that during the voltage drop test, the engine should be at the specified rpm and the battery loaded down so the alternator puts out maximum current flow. Who is correct
Assuming a voltage drop test is being performed on the output wire of the alternator to the battery positive post, the technician who would be correct is: B. Technician B.
What is a voltage drop?A voltage drop can be defined as a measure of the decrease in electrical potential in an electrical circuit, especially along the path of a current that is flowing through it.
How to calculate the amount of voltage?In order to determine the amount of voltage that is running through this circuit, we would apply Ohm's law:
V = IR
Where:
I represents the current.R represents the resistance.V represents the voltage.Assuming a voltage drop test is being performed on the output wire of the alternator to the battery positive post, the technician who would be correct is Technician B because the engine should be at the specified rpm.

Find the differential and evaluate for the given x and dx: y=sin2xx,x=π,dx=0.25
By applying the concepts of differential and derivative, the differential for y = (1/x) · sin 2x and evaluated at x = π and dx = 0.25 is equal to 1/2π.
How to determine the differential of a one-variable function
Differentials represent the instantaneous change of a variable. As the given function has only one variable, the differential can be found by using ordinary derivatives. It follows:
dy = y'(x) · dx (1)
If we know that y = (1/x) · sin 2x, x = π and dx = 0.25, then the differential to be evaluated is:
[tex]y' = -\frac{1}{x^{2}}\cdot \sin 2x + \frac{2}{x}\cdot \cos 2x[/tex]
[tex]y' = \frac{2\cdot x \cdot \cos 2x - \sin 2x}{x^{2}}[/tex]
[tex]dy = \left(\frac{2\cdot x \cdot \cos 2x - \sin 2x}{x^{2}} \right)\cdot dx[/tex]
[tex]dy = \left(\frac{2\pi \cdot \cos 2\pi -\sin 2\pi}{\pi^{2}} \right)\cdot (0.25)[/tex]
[tex]dy = \frac{1}{2\pi}[/tex]
By applying the concepts of differential and derivative, the differential for y = (1/x) · sin 2x and evaluated at x = π and dx = 0.25 is equal to 1/2π.

The three architectural structures, natural or man made, that have withstood the test of time. describe the geometric shapes that they represent or contain are statues.
How are geometric shapes utilized in architecture?Architects use geometry to take a look at and divide areas in addition to draft specified construction plans. Builders and engineers depend upon geometric concepts to create systems safely. Designers practice geometry (in conjunction with color and scale) to make the aesthetically appealing areas inside. Applying geometry in the layout is unavoidable.
Man-Made systems can consist of seawalls, breakwaters, harbor walls, pontoons and piers, to say a few. These may be crafted from a whole lot of substances now no longer constrained to wood, concrete, or metal, in addition to herbal rock that has been installed vicinity as a sea defence.
