Vernier Caliper | Parts, Types, Working, Least …

22/05/2021· Here the main scale has the least count of 1mm and vernier scale has the least count of 0.9mm. So therefore 10 unit of the main scale is 1cm whereas 10 unit of vernier scale is 0.9mm. The unit of the vernier scale is 9mm. So this difference between the main scale and vernier scale which is 0.1mm is the working principle of vernier caliper.

Alloys - What are they? What are common alloys …

12/10/2020· The best way to think of an alloy is as a material that''s made up of at least two different chemical elements, one of which is a metal. The most important metallic component of an alloy (often representing 90 percent or more of the material) is called the main metal , the parent metal , or the base metal .

Which of the following shows a metal, nonmetal, and …

In reactions to form ionic compounds, metals generally 1. lose electrons. 2. become non-metals. 3. do not react. 4. gain electrons

Which of the following elements forms the least …

08/08/2017· As predicted by the generalized solubility rules, only those metal oxides of the nonacidic and feebly acidic ion dissolve in water. The dissolution is highly exothermic generating the hydroxide of the ion. These aqueous solutions are strongly basic. Metal oxides which exhibit this behavior are termed basic oxides because they act as bases.

What Is the Lightest Metal?

08/01/2020· The lightest or least dense metal that is a pure element is lithium, which has a density of 0.534 g/cm 3. This makes lithium nearly half as dense as water, so if lithium was not so reactive, a chunk of the metal would float on water. Two other metallic elements are less dense than water.

I-beam - Wikipedia

An I-beam, also known as H-beam (for universal column, UC), w-beam (for "wide flange"), universal beam (UB), rolled steel joist (RSJ), or double-T (especially in Polish, Bulgarian, Spanish, Italian and German), is a beam with an I or H-shaped cross-section.The horizontal elements of the I are flanges, and the vertical element is the "web".I-beams are usually made of structural steel and are

Which one of the following alkali metals - …

Among the given alkali metals, Li is the smallest in size. Also, it has the highest charge density and highest polarising power. Hence, it attracts water molecules more strongly than the other alkali metals. As a result, it forms hydrated salts such as LiCl.2 H 2 O. The other alkali metals are larger than Li and have weaker charge densities.
