Answer:
Explanation:
Metals are good conductor of electricity, because as per there structure they have free electrons which help them to move freely within the metal thus helps to maintain a good flow of electricity.
This theory has really helped engineers especially for making powerful batteries. As good batteries means amount of electricity drawn from it will be great and that too for longer time.
Hence such metals are used to make batteries that has more number of free electrons and thus can contribute to generate more electricity.

Answer:
4.87×10⁶ kJ
1.63×10⁸ Joules
1015 $
Explanation:
a. To convert the units, you can use this conversion factor:
1 kWh = 3.6×10⁶J
1355 kWh . 3.6×10⁶J / 1 kWh = 4.871×10⁹ J
Now we convert to kJ → 4.87×10⁹ J . 1 kJ/1000J = 4.87×10⁶ kJ
b. In 30 days, we used 1355 kWh so, let's determine the use by day
1355 kWh / 30 day = 45.2 kWh
Now we convert the 45.2 kWh to Joules → 45.2 kWh . 3.6×10⁶J / 1 kWh =
1.63×10⁸ Joules
c. We can make a rule of three, for this:
1 kWh costs $0.749
1355 kWh will pay (1355 . 0.749) / 1 = 1015 $
