Which situation is the best example of inertia?

A situation would be a ball sitting at rest or a ball rolling down a table without any external interference

Explanation:

Inertia is the property of the body which resists any change in the state of motion of the body.

There are three types of inertia.

1. inertia of rest

2. inertia of motion

3. inertia of direction

When a book is placed on the table top, it remains at rest. So, it is the example of inertia of rest.

If a ball is sliding on the floor it continues in motion, it is an example of inertia of motion.

If a car is moving towards east it continues to move n the same direction, it is an example of inertia of direction.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
