Nickel is magnetic.
Brass is a yellow-colored alloy made from copper and zinc, while nickel is a silver-colored metal with a slight blue tint. Brass tends to have a warmer tone and is less shiny than nickel. You can differentiate between the two by comparing their color, shine, and possibly using a magnet (nickel is magnetic, while brass is not).

There are several ways to tell the difference between nickel and silver. Silver is much softer than nickel. However, nickel will shine with a cloth while silver needs special cleaners. Finally, silver is more reflective than nickel.
Nickel silver is an alloy of nickel, copper, and zinc, while sterling silver is an alloy of silver and copper. You can tell the difference between the two by looking for a marking such as "925," which indicates sterling silver's higher silver content compared to nickel silver. Sterling silver will also have a brighter appearance and may tarnish less than nickel silver.
The brass has much lighter color (yellowish to light reddish), then the copper (reddish brown). The brass is copper mixed with zinc. The more copper in the mix, the darker the color.
They are smart enough to recognize the difference between objects of different sizes. They can be trained to learn the names of the objects.
By the color, obviously. NIckel plated flutes are slightly golden and well, silver plated, they have silver color.
The small 50% silver Threepences (16mm) were still being minted for the Colonies from 1942 to 1945 inclusive. The changeover to the 12 sided nickel-brass Threepence (21mm) commenced gradually from 1937.
Brass is an alloy of copper and zinc, giving it a more yellow appearance with slight red tones. Gold, on the other hand, is a precious metal with a distinct bright yellow color and is much softer compared to brass. One way to differentiate them is through a magnet, as brass is not magnetic but gold is not magnetic.
Stainless steel looks shiny. Nickel is duller and darker in color. Stainless looks like the kitchen sink. Nickel more closely matches, well, a nickel. In reality, it is hard to tell the difference. Highly polished nickel is extremely shiny, like a bathroom faucet. That is nickel. Nickels are not made out of nickel anymore anyway. It is too expensive. Nickels and other shiny coins are an aluminum alloy. The above answer is backwards at least with guns. If it is highly polished nickel, it will be very shiny. It it has a duller more bluish look, then it is stainless steel most likely. Take it to your gunsmith for a positive id.
Hard to tell- regular ethanol is about 10% and E85 is about 15% so maybe 5% difference between the two in or normal fuel supply as of 2014. Brass and E85 ethanol are very reactive with each other
No, you cannot differentiate between brass and bronze solely based on sound. Brass is an alloy of copper and zinc, while bronze is an alloy of copper and tin. The compositions of the two alloys affect their physical properties, such as color and hardness.
