The first true US 5 cent nickel containing 75% copper and 25% nickel was minted in 1866 and was called the "Shield" nickel.Before that, the US minted tiny, 90%-silver "half dimes" to handle the 5 cent denomination. Half dimes continued to be minted until 1873, by which time there were enough nickels in circulation.Regardless of popular myths and rumors, half-dimes were the ONLY 5-cent coins to be made of 90% silver. All modern nickels except the famous "war nickels" from WWII are made of the copper-nickel alloy noted above. War nickels were minted from mid-1942 to 1945; they were made of 35% silver, 56% copper, and 9% manganese because nickel metal was needed for the war effort.
False. The inner core of the Earth is composed of solid iron and nickel, while genetic material is found in the nucleus of cells.

True. The center of the Earth is believed to be primarily composed of molten iron and nickel, forming the outer core. The inner core is solid due to high pressure despite its extremely high temperature.
That's NICKEL, not "nickle" The U.S. only struck nickels containing silver from mid-1942 to the end of 1945. Nickel was needed for the war effort, so the coins were made from a small amount of silver mixed with copper and manganese. All other nickels from the start (1866) to today are made of an alloy of 75% copper and 25% nickel.
True. Steel is an alloy made primarily of iron mixed with carbon and other elements like chromium, nickel, and manganese to enhance its properties such as strength, hardness, and corrosion resistance.

No the hovercraft was made by Christopher Cockerell.
True. The inner core of the Earth is solid and is primarily made of iron and nickel. The immense pressure from the layers above keeps the inner core in a solid state, despite its extremely high temperature.
