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.

What It's Made Of. Caulk is made of materials that have been used for centuries and newer chemical substances created through the advances of modern science. You may recognize it in many forms such as the chinking used between logs on a log cabin to the rubbery substance that surrounds a shower enclosure.ave. Caulk is a non-structural, physical compound that provides an airtight, watertight, or non-porous seal. The seal or closure made by caulk is used to prevent something, such as air, water, gas, liquid, or steam, from entering or escaping between two other materials.
