Central heating is often used in cold climates to heat private houses and public buildings. Such a system contains boiler, furnace, heat pump to heat water, steam or air, all in a central location such as furnace room in a home or a mechanical room in a large building. The use of water as the heat transfer medium is known as hydronics.
Answer:
Explanation:
No, the reading is not expected to be accurate. This is because Relative to Earth, the air on Mars is extremely thin. The Martian atmosphere is primarily carbon dioxide with a much lower surface pressure, and Mars does not have oceans and an Earthlike hydrological cycle so latent heat release is not as important as it is for Earth.

Answer:
Option b. Dark spot
Explanation:
Michelson interferometer gives the path difference of the light as path difference, d as twice the distance moved or covered by the mirror 
, x and is given as:
d= 2x
Since, its an even multiple, we obtain a bright fringe
now, when the move half the distance, i.e., 
Therefore, the path difference for half the distance is:
d = x
As it is clear that its an odd multiple which correspond to dark spot as the final image
Is there an image that goes with this question?
