Alpha Centauri A
The two main stars are Alpha Centauri A and Alpha Centauri B, which form a binary pair. They are an average of 4.3 light-years from Earth. The third star is Proxima Centauri. It is about 4.22 light-years from Earth and is the closest star other than the sun

Answer:
How do you find the poles of magnet?
<em>Unless they came marked with “N” or “S,” the poles of a magnet look the same. One easy way to tell which pole is north and which is <u>south is to set your magnet near a compass</u>. The needle on the compass that normally points toward the north pole of the Earth will move toward the magnet's south pole.</em>

Answer:
33,333.3J/s
Explanation:
Energy expended which is the work done in Joule
=250,000J
Time taken to expend the energy =7.5s
Power =Unknown
Formula
Power = <u> </u><u> </u><u> </u><u> </u><u> </u><u>Work</u><u> </u><u> </u><u> </u>
Time
Hence, Power = <u>250,000J</u>
7.5s
Power = 33,333.3J/s
Answer:
a) Mechanical equivalence of heat
Explanation:
heat is an energy that is transferred from one body to another because of a difference in temperature and in any system of physical units, the number of units of work or energy equal to one unit of heat.
Answer:
The intralveolar pressure is 1 mmHg
Explanation:
The transpulmonary pressure is the difference between the alveolar pressure and the intrapleural pressure. It is this gradient between pressures that allows the air to flow during human ventilation.
Writing this into an equation it means that, Ptp = Palv - Pip, so from there we have Palv = Ptp + Pip, or Palv = 5 mmHg - 4 mmHg = 1 mmHg.
