Remember, the cooler stars are white or yellow like the sun, and hottest are blue. Based on that, it should be in this order: Barnard's Star, Polaris, Sirius, and Rigel.
Answer:
Earth rotates in and out of a tidal bulge twice a day.
Earth always has two surrounding gravitational forces, one proceeding from the moon and one from the sun.
The sun's pull, despite the fact our sun is further then the moon, is stronger and creates the high tide, and the moon the low tide. But as we know our earth moves, now exposing the other side to the sun which in turn leaves the other side of earth with the high tides and the other with the low tides. Tides never move, what moves is earth.

Answer: The correct answer is A. During this time, cells take in nutrients, which are important for energy, growth, and repair of the cell.
Interphase is the first phase of the cell cycle. During this phase, the cell takes in nutrients, which are important for energy, growth, and repair of the cell.
In other words, cell prepares for division by growth, synthesizing essential proteins, and duplicating the DNA. This phase occurs prior to cell division.
This phase is primarily divided into G1, S, and G2 phase. G1 and G2 are the gap phases during which cellular growth and synthesis of essential proteins take place.
S phase ( synthesis phase) includes the duplication of the DNA so two identical cells are obtained after cell division.
Thus, the correct statement, which describes the interphase is A.
The flowers of the bunchberry plant open with astonishing force and speed, causing the pollen grains to be ejected out of the flower in a mere .3 ms at an acceleration of 2.5 * 104 m/s^2. The grains are ejected from the flower at 7.5 m/s.
So, in summary, your final answer is 7.5 m/s
