What is the pressure in a gas container that is connected to an open-end U-tube manometer if thepressure of the atmosphere is 75
VARVARA [1.3K]

Answer:

The pressure in a gas container  is 839.44mmHg

Explanation:

Density of Mercury = 13.56g/cm³ = 13556kg/m³

P_{A} = P_{0} +  hρg/ P₀

where, g= acceleration due to gravity, 10m/s²

h= height= 8.6cm = 0.086m

P_{A}= hρg/ P₀

= 0.086 × 13556  × 10

= 11658.16 kgm/ m²s²

= 11658.16 N/m² = 11658.16pa

= 87.4434mmHg

where 1 torr = 1mmHg

P_{0}= 752torr = 752mmHg

P_{A = 752 + 87.4434

= 839.44mmHg

Which of the following is considered a calm area close to the equator resulting in little to no wind?
solong [7]
<h2>Right answer: Doldrums</h2>

These are also called zones of equatorial calm and it is due a climatic phenomenon that is placed near the Earth equator, attributed to the soft winds, that are called calm winds as well; accompanied by systems of abundant rains and heat.

In this area periods of great calm occur when the winds virtually disappear completely, trapping the sailing ships for long periods (days or weeks). This is why the term <em>doldrum</em> became popular as a colloquial expression in the eighteenth century, to refer to "<em>the caprice of the wind that slows down the navigation to sail". </em>


The zone is located in the place where two trade winds meet, this means the trade winds of the northern hemisphere <u>converge</u> with those of the southern hemisphere, that is why this region is related to the <u>intertropical convergence zone</u>.
