Rock climbers reach the top of a large, intrusive rock formation. This landform is located where an ancient volcano once stood. Explain how this landform may have formed.

This landform may have formed by the magma of the volcano making a new landform from over flowing and erupting so many times is formed a new landform

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.
