As hard as lightning? What kind of question is that?
Very Hard
Yes. Rhodium is a hard metal.
Yes, metal is a soild because because metal is made out of steel or other objects that are hard.. because all the objects to MAKE METAL are hard so will metal.
The combination of a hard surface and a soft interior is greatly valued in modern metal engineering because it offers very high stress and fatigue for applications such as gears and anti-friction bearings. Surface-hardened steel is also valued for its low cost and superior flexibility in manufacturing.
i thing it produces sound?
They are either absorbed [softsurface, e.g. wool] or refected [hard surface, e.g. metal]
you go on strike because you dont deserve that if you know you are working very hard.
The fresh surface of pure iron is silver-white.
Probably not, as it is metal, not glass. But it will be dented if landing on a hard surface.
To make a coin, you take 2 pieces of hard metal (usually steel) and engrave a reverse image of what you want the coin to look like on these pieces of metal. This is called the die. You then put the metal between the 2 dies and apply pressure to strike the coin. Ancient and medieval coins used a hammer to strike the coin (often multiple strikes were required) but modern methods use machines to strike the coin and usually only one strike is required except in high-relief and proof coins.
(The Quote came from the 1984 movie "Karate Kid" and the actual quote was "Strike First Strike Hard Show No Mercy".) This quote is accually said by Fleet Admiral William Halsey, during WWII, the "Karate Kid" quote is probably derived from what the Admiral said. and it's: "Strike Fast, Strike Hard, Strike Often".
it is a hard metal.
Hard anodizing: electrolytic passivization of the metallic surface with the scope to obtain an oxide layer with a hardness greater than the hardness of the metal. Frequently used for aluminium.
It is VERY strong cleaning liquid for hard surface like plastic, metal etc. It's blue color.
