What was the result of collisons between the early earth and other smaller protoplanets

Matter within the protoplanets was absorbed and became the Earth’s core Matter within the protoplanets formed the Earth’s early atmosphere. The trajectory of their motion and energy too can play a vital impact.

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.
