Wood, plastic, rubber and air are good insulators because they don’t have free electrons.
True because school doesn't dictate what job you want in the future
-- reduce the length of a wire to 1/2 . . . cut the resistance in half
-- reduce the diameter to 1/4 . . . reduce the cross-section area by (1/4²) . . . increase the resistance by 16x .
-- R2 = (R1) · (1/2) · (16) = 8 · R1
<em>-- R2 / R1 = 8</em>
Answer:
Depends
Explanation:
This depends on the amount of work the energy requires
The differences in energy released by earthquakes are too large to express with linear scales.
