Aluminum metal is a good example of conductor of electricity while glass and paper are good example of insulators.
<h3>What is a conductor?</h3>
A conductor is material that allows easy passage of electric current through the.
<h3>Examples of conductors</h3>
All metals are good examples conductors. such as aluminum, iron, silver, etc.
<h3>What is a non conductor?</h3>
A non conductor or insulator is a material which does not allow easy passage of electric current through them.
<h3>Examples of insulators</h3>
Thus, aluminum metal is a good example of conductor of electricity while glass and paper are good example of insulators.

Answer:
DU = 21 KJ
Explanation:
Given the following data;
Quantity of heat = 125 KJ
Work = 104 KJ
To find the change in internal energy;
Mathematically, the change in internal energy of a system is given by the formula;
DU = Q - W
Where;
DU is the change in internal energy.
Q is the quantity of energy.
W is the work done.
Substituting into the formula, we have;
DU = 125 - 104
DU = 21 KJ
Answer:
76969.29 W
Explanation:
Applying,
P = F×v............. Equation 1
Where P = Power, F = force, v = velocity
But,
F = ma.......... Equation 2
Where m = mass, a = acceleration
Also,
a = (v-u)/t......... Equation 3
Given: u = 0 m/s ( from rest), v = 12.87 m/s, t = 3.47 s
Substitute these values into equation 3
a = (12.87-0)/3.47
a = 3.71 m/s²
Also Given: m = 1612 kg
Substitute into equation 2
F = 1612(3.71)
F = 5980.52 N.
Finally,
Substitute into equation 1
P = 5980.52×12.87
P = 76969.29 W
