Answer: 1.Spectroscopes breaks the light from a single material into its component colors the way a prism splits white light into a rainbow. It records this spectrum, which allows scientists to analyze the light and discover properties of the material interacting with it.
2.Optical Telescopes The now-indispensable optical telescope instrument was pioneered by Galileo Galilei in 1609, although others had created similar tools by then
2.A stellar spectrum can reveal many properties of stars, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.
3.Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. The process of star formation takes around a million years from the time the initial gas cloud starts to collapse until the star is created and shines like the Sun.Once the pressure and the temperature inside get high enough for nuclear fusion to ignite, it creates a star.

(1)
(2)
(3)
Where:
is the horizontal distance traveled by the golf ball
is the golf ball's initial velocity
is the angle (it was a horizontal shot)
is the time
is the final height of the ball
is the initial height of the ball
is the acceleration due gravity
is the final velocity of the ball
Let's begin by finding from (2):
(4)
(5)
(6)
Substituting (6) in (1):
(7)
Finding :
(8)
Substituting in (3):
(9)
Finally:
This is probably referring to the process of nuclear fission.
Answer:
analyze, assess or interpret an historical event, era, or phenomenon,.
Explanation:
Secondary sources are works that analyze, assess or interpret an historical event, era, or phenomenon, generally utilizing primary sources to do so. Secondary sources often offer a review or a critique. Secondary sources can include books, journal articles, speeches, reviews, research reports, and more.
