Laplace's Nebular hypothesis suggested that after the formation of the sun, a nebular cloud would throw off rings of material that would eventually form planets.

Options:
Cool down
Heat up
Spin faster
Slow down

Answer 1

Laplace's Nebular Hypothesis indeed suggests that a nebular cloud, during its contraction, would lead to the formation of a rotating disk of material. As the nebula contracts, it would:

- **Cool down**: As the material spreads out and forms rings, the temperature of the cloud generally decreases due to the loss of potential energy and the processes involved in the formation of planets.

- **Spin faster**: As the nebula contracts, it must conserve angular momentum, which leads to an increase in rotation speed.

So, the two appropriate options from your list in the context of Laplace's Nebular Hypothesis would be: **Cool down** and **Spin faster**.
