If a star is located 100 light years from earth, what can you conclude about the light from the star?

Light from star would take 100 years to reach the Earth.

Explanation:

1 light year can be defined as the distance which light travels in one year in space.

1 light year = speed of light × 1 year

1 light year = 9.46 × 10¹⁵ m

A star at a distance of 1 light year means that observer on earth would see the first light from the star after 1 year.

If a star is located 100 light years from the Earth, the light from the star will reach the Earth in 100 years.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
