lose weight because water exerts an upward buoyant force on the object, reducing the effective weight measured by the spring scale.
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.
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.
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.
The assumption made is that the height of the object is constant as it is lowered into the deep hole. This means that the potential energy of the object decreases linearly with respect to the depth of the hole.
As the object is lowered into water, the buoyant force acting on it increases because more of the object is submerged in the water, displacing a greater volume of water. This increase in buoyant force helps to counteract the gravitational force acting on the object, making it easier to hold or push the object deeper into the water.

are formed by electrons that are delocalized throughout the object bonded by the metallic bonds.

Yes, an object can be metallic without being classified as a metal. For instance, some alloys or metallic compounds may exhibit metallic properties such as luster, conductivity, and malleability, yet they do not fall under the traditional definition of metals. Additionally, certain non-metallic materials, like certain types of conductive polymers, can also display metallic characteristics.
