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.

Polystyrene-based packing peanuts were developed and patented by Tektronix Inc. They were made commercially available circa 1965 by Dow Chemical.Originally made from 100% virgin polystyrene resin, peanuts made from 100% recycled polystyrene have been commercially available since the mid-90s.hey are shaped to interlock when compressed and free flow when not compressed. They are roughly the size and shape of an unshelled peanut and commonly made of expanded polystyrene foam. Two to three inches (50â75 mm) of peanuts are typically used for cushioning and void filling packaging applications.
