Everything dumped into a watershed drains into the same place. true or false?

True.

Explanation:

Water is one of the most important component present in the earth. More than 70% of the earth's surface is covered with water but only 2-3% is used for the consumption by living organisms.

Watershed management is an important practice to save and manage the water resource. Different things are used for the management of the water shed. All the things that are drained into the water shed are all collected at the same place.

Thus, the given statement is correct.

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.
