CoachSome disadvantages of metallic money include the risk of theft due to its intrinsic value, the cost and inconvenience of carrying heavy coins, and the need for secure storage facilities to prevent loss. Additionally, metallic money can be subject to wear and tear, leading to deterioration of its value over time.

What happens when a charged object is brought near a metallic object that is not charged?
When a charged object is brought near a neutral metallic object, the charges in the metallic object redistribute themselves. This causes the charges within the metallic object to separate, with opposite charges being attracted to the charged object. This redistribution of charges induces a temporary charge separation in the metallic object, known as polarization.
What happens when a charged insulator is placed near an uncharged metallic object, and how does the presence of the insulator affect the behavior of the metallic object?
When a charged insulator is placed near an uncharged metallic object, the charges in the insulator induce opposite charges in the metallic object through electrostatic induction. This causes the metallic object to become polarized, with one side becoming positively charged and the other side becoming negatively charged. The presence of the insulator affects the behavior of the metallic object by creating an attractive force between the opposite charges, causing the metallic object to be attracted towards the charged insulator.
Is the reflection of light by a shiny metallic object a physical change?
Yes, the reflection of light by a shiny metallic object is a physical change. This is because the metallic object remains the same substance before and after reflecting light, with no new substances formed.
What mineral reflection of light from a minerals surface?
The mineral property you are referring to is known as luster. Luster describes how a mineral's surface reflects light and can be categorized as metallic or non-metallic. Metallic luster appears shiny and reflective like metal, while non-metallic luster includes subcategories such as vitreous, pearly, greasy, and silky, depending on the appearance of the reflection.
What piece of equipment would iron and other metallic objects use to separate?
Iron and other metallic objects can be separated using a magnet. The magnet will attract the iron and other ferrous materials, allowing them to be easily separated from non-metallic materials.
