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.
