1. choose the best answer using the picture of the measuring tool.

there is no motion or change of direction when forces are ____
stable
unstable
unbalanced
balanced

Explanation:

Question 8

Copper is a good conductor of electricity. Wood and plastic do not conduct electricity well. Conductors allow electricity to flow through them. Insulators do not. Developers and dischargers are not relevant terms here.

When forces are balanced, there is no net force acting on an object. According to Newton's first law, an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Stable and unstable are not the correct terms related to force - motion relationship in this context. Unbalanced forces cause motion or change in direction.

Answer:

A. conductors
