Scientist have discovered a new pathogen named Virus X. This infection causes its victims to suffer from severe diarrhea and is spreading quickly across major cities around the world. During their investigation, these researchers tracked the virus back to a population of pigs in Asia. These animals were not affected by the disease themselves but large numbers of the virus were found in their feces. In particular, when visiting one farm, scientists observed workers routinely going from taking care of the pigs to picking fruits and vegetables without washing their hands. Fruits and vegetables that were contaminated with pig feces would act as a...

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.

and after water is usually warmed by the sun the water temperature raises and then evaporates .

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
