Stage 2 (short term swim failure) occurs 3-30 minutes following immersion in cold water. what happens in stage 2 if cold water immersion?

Stage 2: Short-term "swim failure" occurs 3–30 minutes following immersion in cold water. The muscles and nerves in the arms and legs cool quickly. Manual dexterity, hand grip strength, and speed of movement all can drop by 60%–80%. Even normally strong persons can lose the strength necessary to pull themselves out of the water or even to keep their head above water. Death occurs by drowning. Hope this helped :p

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.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
