The lowest type of cloud is called?

I know four

1. stratocumulus

2. stratus

3. cumulus

4. cumulonimbus

Explanation:

Stratocumulus.

Explanation: Stratocumulus is the closest / lowest type of cloud.

Although there are 4 types of clouds Stratocumulus is th lowest.

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.
