Do you think it is possible that a carbon star could harbor an advanced civilization? Explain your reasoning

What will be an ideal response?


A carbon star is a very old low-mass star, after it has passed through the red giant phase. Earth may survive the red giant phase of the Sun, as planets in similar systems have, but. the cool red radiation may make processes such as photosynthesis difficult. Maybe an advanced civilization could have developed around this star, but it would have had to make special arrangements to survive the red giant phase of its mother star.

Slanting Surfaces Without Friction: A slanted roof rises at 35° above the horizontal, and the straight-line distance from the top of the roof to the bottom edge is 4.5 m. The roof is covered with ice, so it offers no friction to objects sliding on it. A piece of ice at the top suddenly breaks loose and begins to slide down from rest.(a) How long will it take for the ice to reach the bottom edge of the roof?(b) How fast will the ice be traveling just as it reaches the bottom edge?
