Suppose we obtain a single, detailed (high-resolution) spectrum of a star located many light-years away. what can we learn about the star? sort each of the following characteristics of a star into the correct bin based on whether we can or cannot learn it from the single spectrum. view available hint(s)

An object is dropped from a tower, 400 ft above the ground. the object's height above ground t seconds after the fall is s(t)equals400 minus 16 t squared. determine the velocity and acceleration of the object the moment it reaches the ground. the velocity of the object the moment it reaches the ground is nothing ft/s.

Which object is most likely represented by a dot?
