Which of these sources add water to lakes

what are the sources bff

Explanation:

Rain runoff, groundwater, melting snow.

Explanation:

Rain flows through various paths and goes into lakes, carrying various types of small leaves or soil particles along with it into the lake.

Groundwater can also form lakes and is the source of freshwater.

The melting snow is also the source of freshwater that flows and reaches the nearby ponds or lakes present in the nearby areas.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
