Basically, we want to see the distance in terms of thickness. So, for this rectilinear motion at constant acceleration, the equation to be used is:
x = v₀t + 0.5at²
First, let's determine t using the equation:
a = |v - v₀|/t
300 m/s² = |0 - 92.8 km/h * 1,000 m/1 km * 1 h/3600 s|/t
t = 0.086 seconds
x = (92.8 km/h * 1,000 m/1 km * 1 h/3600 s)(0.086 s) + 0.5(300 m/s²)(0.086 s)²
x = 3.33 meters
The conductors carry current which is required to power appliances and lights. The insulators are around the conductors to keep them from touching each other, from touching the house, or any other thing besides what they are powering. Without insulators, houses would be likely to burn down
