A light bulb emitting 1750 of luminous flux shines on a book that is 3.0 m away. In general terms, how will illuminance change as a person in the room moves the book closer to the light bulb? How does this illustrate an inverse-square relationship?

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

d) physical means can be used to separate the components of air.
