Answer:Spectroscopy helps astronomers to determine the composition, temperature, density, and motion of an object.
Infrared spectroscopy helps to identify the atoms and molecules in the object.
The red shift or blue shift (Doppler Effect) in a spectral line tells how fast the object is receding from Earth or coming toward it.
The Doppler shift enables astronomers to discover extrasolar planets.
As a planet orbits its star, the star is alternately moving away from or toward us.
Astronomers can use the Doppler shifts to calculate the speed of the star and the mass of the planet that is tugging on it.
Explanation:
Cory is reluctant to leave her home and attend college despite just being finished with her teenage years. Usually, the people of this age are explorative and are trying to find their identity in the world separately, but Cory seems to stay isolated even from Mike, which indicates that she might be going through the stage of stress. Stress makes a person to avoid any kind of interaction with other people and inhibits the urge to explore the life outside one's comfort zone. So, Cory is going through the stress stage.
