<h3><u>Answer;</u></h3>

A. The meridian at which longitude is defined to be 0 degrees

<h3><u>Explanation;</u></h3>
  • <em><u>Longitudes are imaginary lines going from south pole to north pole. These lines are known as meridians. Zero degrees longitude is an imaginary line known as the Prime Meridian or the Greenwich meridi</u></em>an.
  • The Prime meridian acts as the starting point for measuring distance both east and west around the Earth. The meridian runs through Greenwich, England and is internationally accepted as the line of 0 degrees longitude.
  • The lines of all longitudes or meridians are great circles, unlike in the case of lines of latitude where only the equator is a great circle.

I have a question, it concerns hydrostatic buoyancy and Archimedes' law.
saw5 [17]

Answer: the lvl wud remain the same

Explanation: as per Archimedes Principle, the weight of the water displaced by the object is equal to the weight of the object. When the ship initially went into the pool, it wud hv displaced some water. When the anchor is dropped, the level does not change coz the anchor was already in the ship and no extra weight has been added, so the weight of the anchor has already been accounted for in the first place when the ship was first placed in the pool

A 2.5-L tank initially is empty, and we want to fill it with 10 g of ammonia. The ammonia comes from a line with saturated vapor
Alex17521 [72]

Answer:

592.92 x 10³ Pa

Explanation:

Mole of ammonia required = 10 g / 17 =0 .588 moles

We shall have to find pressure of .588 moles of ammonia at 30 degree having volume of 2.5 x 10⁻³ m³. We can calculate it as follows .

From the relation

PV = nRT

P x 2.5 x 10⁻³ =  .588 x 8.32 x ( 273 + 30 )

P = 592.92 x 10³ Pa
