The cost of the electricity if 42000 kWh of electricity is used is ; $1680
<h3>Determine the cost of electricity </h3>
<u>Given that ;</u>
value of electricity used = 42000 kWh
cost rate of electricity = $0.04/kWh
Final step : Determine the total cost of electricty used
unit cost = $0.04/kWh
Totals cost = unit cost * value of electricity used
= 0.04 * 42000 = $1680
Hence we can conclude that The cost of the electricity if 42000 kWh of electricity is used is ; $1680.

Evaporation
Explanation:
Evaporation is one change that would cause more water to evaporate from a stream.
Evaporation is a phase change in which liquid is changed into its gaseous form.
- When a substance is heated from solid to liquid, it melts.
- After melting, additional heat causes a phase change that allows for the liquid to change to gases.
- In the water cycle, the sun provides heat energy that causes surface water in streams to be heated.
- This leads to evaporation of the surface water into the atmosphere where they can be condensed to form precipitation.
