Angular velocity = 7.3 x 10 -5 rad/s. thus, the speed of any point on the earth's surface at the equator due to earth's rotation is, V = r $\omega$ = 6.4 x 10 6 x 7.3 x 10 -5 m/s = 470 m/s. The examples based on Rotational Speed are given below : Back to Top.
Sarking is a layer of flexible insulation typically installed under roof tiles when a home is being constructed.It consists of aluminum foil laminated onto paper or plastic backing with a flame retardant adhesive and fibreglass reinforcing mesh, and is manufactured in sheet form.Sarking performs a dual function, helping to keep your home insulated from the heat of summer whilst retaining warmth in the winter.t consists of aluminum foil laminated onto paper or plastic backing with a flame retardant adhesive and fibreglass reinforcing mesh, and is manufactured in sheet form.

Bituminous felt laid across rafters of a pitched roof. Pitched roofs using sarking felt underlay provide watertightness.In many countries, including Scotland, it is usual to 'sark' the roof with a covering of timber boards or sheet composite over the rafters.sing a sarking board also opens up the way for exposing the underside of this board and the roof timbers, since it becomes possible to support the timber frame roof insulation material on the top side of this. I hope this answered your question. If so please ACCEPT my answer.
