A permanent magnet (in contrast to an electromagnet).
The roughness of the two objects coming in contact determines the degree of friction.
The phenomena of sending back of light is called reflection of light. And the surfaces which reflects light back are called reflecting surfaces.
They could if they were a source of it. Say if you heated a shiny steel pan in the oven. However shiny objects typically reflect IR better that emitting it. Dark objects are better at absorbing and emitting IR.
The types of materials involved, any third party (like sand or grease), the surface finish of the two objects where they contact, the temperature of the interfacing surfaces, and the normal force.
Objects move on different surfaces by friction.
Surfaces that are smooth and reflective, such as mirrors or water surfaces, can form clear images of objects. Additionally, curved surfaces like lenses or spherical mirrors can also create focused images of objects.

Objects move on different surfaces by friction.
Objects seen by reflected light are those that do not emit their own light but instead bounce light off their surfaces. This includes everyday items like furniture, buildings, and people, which become visible when light from a source, such as the sun or a lamp, strikes them and reflects back to our eyes. Reflective surfaces, like mirrors or water, can also enhance visibility by producing clear reflections of surrounding objects.
Yes, salt water can effectively disinfect surfaces and objects due to its antimicrobial properties.
Non-alcohol wipes are commonly used for cleaning surfaces, removing dirt and germs, and disinfecting objects. They are often gentler on sensitive surfaces like electronics and screens, making them suitable for use on items that may be damaged by alcohol-based products.
The force that resists the motion of objects or surfaces as they move over one another is called friction. It occurs due to the interactions between the surfaces of objects in contact with each other.

smooth surfaces
When two solid objects are rubbed together, kinetic friction occurs. This type of friction opposes the direction of motion between the surfaces of the objects and is caused by the microscopic interactions between the surfaces. The rougher the surfaces and the greater the force pressing the surfaces together, the stronger the kinetic friction.
