Answer:
Electricity is most often generated at a power plant by electromagnetic generators.
Answer:
the answers the correct one is: the time increases
Explanation:
When an insulating material is placed in the cavity of a wall the thermal conductivity of the system increases, therefore the temperature changes take longer.
P= dQ / dt = K A dT / dx
when placing insulation the value of k is less
When reviewing the answers the correct one is: the time increases
