There are different kinds of conductors, most notably electrical and thermal conductors. But they are often inclusive of each other (electrical conductors are typically good thermal conductors).
A conductor transmits something through its body with high efficiency while an insulator does not transmit very well. In the case of electricity, a conductor transmits electrical energy between two points while an insulator blocks the flow of electricity.
Two examples of conductors are copper and silver. Two examples of insulators are wood and styrofoam.

According to given condition there is no height(m) given from roof of building to the ground, there height given 18 m at a point above the ground. So, h=18m , mass=3kg , g=9.8m/s2 P.E=mgh P.E=(3)(9.8)(18) P.E=529J
Answer:
d=510.2m
t=10.2s
Explanation:
The formulas for accelerated motion are:

From them we can get
.
We have:

And substitute:

We multiply both sides by 2a, and continue:

Being d the displacement
, we have 
For our exercise, we will write this as:

And taking upwards direction positive and imposing final velocity 0m/s (for maximum height), we have:

For the time we use:

B
add them all by direction
