Question

A charged drinking plastic straw is brought near another suspended plastic straw, that
is (a) similarly charged (b) uncharged. Explain what we would observe in each
case and why.​

Answer 1

During the sunrise the sun is set close to the Earth's horizon, and therefore light travels a longer distance through the atmosphere of the Earth.

This is the reason sun appear reddish early in the morning. The astronaut will not observe this phenomenon on the moon's surface, because the moon has no atmosphere.
