When calculating the angular velocity of the Earth as it completes a full rotation on its own axis (a solar day), this equation is represented as: Ï avg = 2Ïrad/1day (86400 seconds), which works out to a moderate angular velocity of 7.2921159 Ã 10 -5 radians/second.

The flexible membrane is usually installed under the battens to provide thermal insulation and to prevent water and dust penetration in the roof space.In bushfire prone areas flying embers cannot enter this space through the roof due to sarking protection.he flexible membrane is usually installed under the battens to provide thermal insulation and to prevent water and dust penetration in the roof space.
