Answer:
For starters, “dark side” is a misnomer. The far side may be constantly facing away from Earth, but as it orbits the Earth it sometimes faces the sun just as the bright side does. Thus the far side is subject to the same day/night temperature extremes as the side facing Earth.
Explanation:
If one knew the luminosity of a star and measured its apparent brightness, which expression would one use to calculate the distance to the star
The expression which one would use to calculate the distance to the star is distance = sq. root. of (luminosity/4pi*apparent brightness)
What is Distance?
This is a scalar quantity and refers to how much ground a body has covered.
In a situation where parameters such as luminosity of a star and measured its apparent brightness are known then the distance to the star will be:
Distance= √(luminosity/4pi*apparent brightness)

(b) When the taps are opened, water flows in the pipe for some time. The diagram shows the final water level in container (i) Complete the diagram to show the final water level in container B.
(ii) Explain why the water starts to flow and then stops.
ii) The pressure difference in the two containers starts the flow of the water from container A to B until the pressure becomes equal in both the containers. Pressure causes force on water, because pressure = force/area
