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.

Caulking is both the processes and material (also called sealant) to seal joints or seams in various structures and some types of piping.The oldest form of caulking is used to make the seams in wooden boats or ships watertight, by driving fibrous materials into the wedge-shaped seams between boards.A related process was formerly employed to join sections of cast iron sewerage pipe.he oldest form of caulking is used to make the seams in wooden boats or ships watertight, by driving fibrous materials into the wedge-shaped seams between boards.
