considering what you have learned in this lab and in class, write a hypothesis to explain why we observe a higher fraction of elliptical galaxies within a cluster and a higher fraction of spiral galaxies in the field. think about how being in a crowded cluster versus alone might affect the morphology or appearance of a particular galaxy.

If y gets smaller as x gets bigger and y have an relationship?

What kind of simple machine is a catapult?

The illuminance of a surface varies inversely with the square of its distance from the light source. if the illuminance of a surface is 120 lumens per square meter when its distance from a certain light source is 6 meters, by how many meters should the distance of the surface from the source be increased to reduce its illuminance to 30 lumens per square meter?
