Outline the three steps to the solar nebular theory
What will be an ideal response?
The solar nebula theory implies that the planets formed along with the sun and undergoes three steps.
Step 1: A rotating cloud of gas contracts and flattens to form a thin disk of gas.
Step 2: Form a thin disk of gas and dust around the forming sun at the center.
Step 3: Planets grow from gas and dust in the disk and are left behind when the disk clears.
OR could simplify with these terms: heating, spinning, flattening

A laser beam passes through a thin slit. When the pattern is viewed on a screen 1.25 m past the slit, you observe that the fifth-order dark fringes occur at ±2.41 cm from the central bright fringe
The entire experiment is now performed within a liquid, and you observe that each of the fifth-order dark fringes is 0.790 cm closer to the central fringe than it was in air. What is the index of refraction of this liquid? A) 1.33 B) 1.40 C) 1.49 D) 1.62 E) 3.05
