Which is a step of the scientific method in environmental science? A. Testing a hypothesis B. Carrying out research C. Collecting ideas from boocks is a step in the scientific method. The step that follows this step involves forming A. a judgment B. a conclusion C .notes .

A. testing a hypothesis

Explanation:

Because you do experiments to test the hypothesis or educated guess.

the answer is a hypothesis

Explanation:

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.

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.
